Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Springer Verlag, 10638, 802-809, 2017, Peer-reviwed, To understand the processing mechanism of sensory information in the brain, it is necessary to simulate a huge size of network that is represented by a complicated neuron model imitating actual neurons. However, such a simulation requires a very long computation time, failing to perform computer simulation with a realistic time scale. In order to solve the problem of computation time, we focus on the reduction of computation time by GPGPU, providing an efficient method for simulation of huge number of neurons. In this paper, we develop a computational architecture of GPGPU, by which computation of neurons is performed in parallel. Using this architecture, we show that the GPGPU method significantly reduces the computation time of neural network simulation. We also show that the simulations with single and double float precision give little significant difference in the results, independently of the neuron models used. These results suggest that the GPGPU computation with single float precision could be a most efficient method for simulation of a huge size of neural network.
International conference proceedings, English - Neural Representation of Object’s Shape at the Electroreceptor Afferents on Electrolocation
Kazuhisa Fujita; Yoshiki Kashimori
Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Springer Verlag, 10636, 877-884, 2017, Peer-reviwed, A weakly electric fish can recognize object’s shape in the complete darkness. The ability to recognize object’s shape is provided by the electrosensory system of the fish. The fish generates an electric field using its electric organs (EOD: electric organ discharge). An object around the fish modulates the self-generated EOD. Electroreceptor afferents on the fish’s body surface convert the EOD amplitude modulation into firings. The fish can extract information about object’s shape from the EOD amplitude modulation using its electrosensory system. In the present study, we calculated the EOD amplitude modulation evoked by objects that were various shapes and firing patterns of the electroreceptor afferents evoked by the EOD amplitude modulation using computer simulation. We found that the EOD amplitude modulation can be represented by firing patterns of the electroreceptor afferents. Furthermore, we demonstrated that the feature of object’s shape appears in the variation of the peak of firing rate with the rotation of the object.
International conference proceedings, English - A neural mechanism of dynamic gating of task-relevant information by top-down influence in primary visual cortex
Akikazu Kamiyama; Kazuhisa Fujita; Yoshiki Kashimori
BIOSYSTEMS, ELSEVIER SCI LTD, 150, 138-148, Dec. 2016, Peer-reviwed, Visual recognition involves bidirectional information flow, which consists of bottom-up information coding from retina and top-down information coding from higher visual areas. Recent studies have demonstrated the involvement of early visual areas such as primary visual area (V1) in recognition and memory formation. V1 neurons are not passive transformers of sensory inputs but work as adaptive processor, changing their function according to behavioral context. Top-down signals affect tuning property of V1 neurons and contribute to the gating of sensory information relevant to behavior. However, little is known about the neuronal mechanism underlying the gating of task-relevant information in V1. To address this issue, we focus on task-dependent tuning modulations of V1 neurons in two tasks of perceptual learning. We develop a model of the V1, which receives feedforward input from lateral geniculate nucleus and top-down input from a higher visual area. We show here that the change in a balance between excitation and inhibition in V1 connectivity is necessary for gating task-relevant information in V1. The balance change well accounts for the modulations of tuning characteristic and temporal properties of V1 neuronal responses. We also show that the balance change of V1 connectivity is shaped by top-down signals with temporal correlations reflecting the perceptual strategies of the two tasks. We propose a learning mechanism by which synaptic balance is modulated. To conclude, top-down signal changes the synaptic balance between excitation and inhibition in V1 connectivity, enabling early visual area such as V1 to gate context-dependent information under multiple task performances.

International conference proceedings, English - A Neural Mechanism of Taste Perception Modulated by Odor Information
Takahiro Shimemura; Kazuhisa Fujita; Yoshiki Kashimori
CHEMICAL SENSES, OXFORD UNIV PRESS, 41, 7, 579-589, Sep. 2016, Peer-reviwed, Taste perception is significantly affected by other sensory modalities such as vision, smell, and somatosensation. Such taste sensation elicited by integrating gustatory and other sensory information is referred to as flavor. Although experimental studies have demonstrated the characteristics of flavor perception influenced by other sensory modalities and the involved brain areas, it remains unknown how flavor emerges from the brain circuits. Of the involved brain areas, orbitofrontal cortex (OFC), as well as gustatory cortex (GC), plays a dominant role in flavor perception. We develop here a neural model of gustatory system which consists of GC and OFC networks and examine the neural mechanism of odor-induced taste perception. Using the model, we show that flavor perception is shaped by experience-dependent learning of foods with congruent taste-odor pairs, providing a unique representation of flavor through the interaction between OFC and GC neurons. Our model also shows that feedback signals from OFC to GC modulate the dynamic stability of taste attractors in GC, leading to the enhancement or suppression of taste responses by smells. Furthermore, modeling shows that spatial variability in GC activity evoked by tastants determines to what extent odor enhances congruent taste responses. The results suggest that flavor perception is deeply associated with dynamic stability of GC attractors through the interaction between GC and OFC.

Scientific journal, English - A neural mechanism of phase-locked responses to sinusoidally amplitude-modulated signals in the inferior colliculus
Takayuki Kato; Kazuhisa Fujita; Yoshiki Kashimori
BIOSYSTEMS, ELSEVIER SCI LTD, 134, 24-36, Aug. 2015, Peer-reviwed, The central nucleus of the inferior colliculus (ICc) is an auditory region that receives convergent inputs from a large number of lower auditory nuclei. ICc neurons phase-lock to low frequencies of sinusoidally amplitude-modulated (SAM) signals but have a different mechanism in the phase-locking from that in neurons of lower nuclei. In the mustached bat, the phase-locking ability in lower nuclei is created by the coincidence of phase-locked excitatory and inhibitory inputs that have slightly different latencies. In contrast, the phase-locking property of ICc neurons is little influenced by the blocking of inhibitory synapses. Moreover, ICc neurons exhibit different characteristics in the spike patterns and synchronicity, classified here by three types of ICc neurons, or sustained, onset, and non-onset phase-locking neurons. However it remains unclear how ICc neurons create the phase-locking ability and the different characteristics. To address this issue, we developed a model of ICc neuronal population. Using this model, we show that the phase-locking ability of ICc neurons to low SAM frequencies is created by an intrinsic membrane property of ICc neuron, limited by inhibitory ion channels. We also show that response characteristics of the three types of neurons arise from the difference in an inhibitory effect sensitive to SAM frequencies. Our model reproduces well the experimental results observed in the mustached bat. These findings provide necessary conditions of how ICc neurons can give rise to the phase-locking ability and characteristic responses to low SAM frequencies. (C) 2015 Elsevier Ireland Ltd.

Scientific journal, English - Decoding Word Information from Spatiotemporal Activity of Sensory Neurons
Kazuhisa Fujita; Yusuke Hara; Youichi Suzukawa; Yoshiki Kashimori
COGNITIVE COMPUTATION, SPRINGER, 6, 2, 145-157, Jun. 2014, Peer-reviwed, Spatiotemporal activity of neurons is ubiquitous in sensory coding in the CNS. It is a fundamental problem for sensory perception to understand how sensory information is decoded from the spatiotemporal activity. However, little is known about the decoding mechanism. To address this issue, we are concerned with auditory system as a model system exhibiting spatiotemporal activity. We present here a model of auditory cortex, which performs a hierarchical processing of auditory information. The model consists of three layers of two-dimensional networks. The first layer represents auditory stimulus as a spatiotemporal activity of neurons. The second layer consists of feature-detecting neurons, which extract the features of phonemes and their overlaps from the spatiotemporal activity of the first layer. The third layer combines information of the sound features encoded by the second layer and decodes word information about the sound stimulus as a temporal sequence of attractors. Using the model, we show how the information of phonemes and words emerge in the hierarchical processing of the auditory cortex. We also show that the overlap between phonemes plays a crucial role in linking the attractors of phonemes. The present study may provide a clue for understanding the mechanism by which word information is decoded from spatiotemporal activity of neurons.
Scientific journal, English - Neural mechanism of dynamic responses of neurons in inferior temporal cortex in face perception
Yuichiro Yamada; Yoshiki Kashimori
COGNITIVE NEURODYNAMICS, SPRINGER, 7, 1, 23-38, Feb. 2013, Peer-reviwed, Understanding the neural mechanisms of object and face recognition is one of the fundamental challenges of visual neuroscience. The neurons in inferior temporal (IT) cortex have been reported to exhibit dynamic responses to face stimuli. However, little is known about how the dynamic properties of IT neurons emerge in the face information processing. To address this issue, we made a model of IT cortex, which performs face perception via an interaction between different IT networks. The model was based on the face information processed by three resolution maps in early visual areas. The network model of IT cortex consists of four kinds of networks, in which the information about a whole face is combined with the information about its face parts and their arrangements. We show here that the learning of face stimuli makes the functional connections between these IT networks, causing a high spike correlation of IT neuron pairs. A dynamic property of subthreshold membrane potential of IT neuron, produced by Hodgkin-Huxley model, enables the coordination of temporal information without changing the firing rate, providing the basis of the mechanism underlying face perception. We show also that the hierarchical processing of face information allows IT cortex to perform a "coarse-to-fine" processing of face information. The results presented here seem to be compatible with experimental data about dynamic properties of IT neurons.

Scientific journal, English - Modeling the electric image produced by objects with complex impedance in weakly electric fish
Kazuhisa Fujita; Yoshiki Kashimori
BIOLOGICAL CYBERNETICS, SPRINGER, 103, 2, 105-118, Aug. 2010, Peer-reviwed, Weakly electric fish generate an electric field around their body by electric organ discharge (EOD). By measuring the modulation of the electric field produced by an object in the field these fish are able to accurately locate an object. Theoretical and experimental studies have focused on the amplitude modulations of EODs produced by resistive objects. However, little is known about the phase modulations produced by objects with complex impedance. The fish must be able to detect changes in object impedance to discriminate between food and nonfood objects. To investigate the features of electric images produced by objects with complex impedance, we developed a model that can be used to map the electric field around the fish body. The present model allows us to calculate the spatial distribution of the amplitude and phase shift in an electric image. This is the first study to investigate the changes in amplitude and phase shift of electric images induced by objects with complex impedance in wave-type fish. Using the model, we show that the amplitude of the electric image exhibits a sigmoidal change as the capacitance and resistance of an object are increased. Similarly, the phase shift exhibits a significant change within the object capacitance range of 0.1-100 nF. We also show that the spatial distribution of the amplitude and phase shifts of the electric image resembles a "Mexican hat" in shape for varying object distances and sizes. The spatial distribution of the phase shift and the amplitude was dependent on the object distance and size. Changes in the skin capacitance were associated with a tradeoff relationship between the magnitude of the amplitude and phase shift of the electric image. The specific range of skin capacitance (1-100 nF) allows the receptor afferents to extract object features that are relevant to electrolocation. These results provide a useful basis for the study of the neural mechanisms by which weakly electric fish recognize object features such as distance, size, and impedance.
Scientific journal, English - A quantitative measure for discriminating between self and non-self antigens in immune response
Yoshiki Kashimori; Yoshihiro Ochi; Takeshi Kambara
BIOSYSTEMS, ELSEVIER SCI LTD, 100, 3, 231-237, Jun. 2010, Peer-reviwed, We present a new theory of how lymphocyte antigen interaction is governed. We present 'chronicity', a quantitative record of previous lymphocyte antigen interactions, which is used to regulate lymphocyte behavior. When the chronicity of a lymphocyte increases with the interaction and gets beyond the lower threshold, the lymphocyte can proliferate. Non-self antigens cause lymphocyte proliferation which destroys the antigen. However, self antigens are not destroyed. When the chronicity gets beyond the upper threshold, the lymphocytes get in the tolerance state ensuring non-destruction of self antigens. The discrimination between self and non-self results from the difference in the termination process between self and non-self antigens, caused by the difference in the frequency between interaction of lymphocyte with both antigens.

Scientific journal, English - Functional connections between visual areas in extracting object features critical for a visual categorization task
Mitsuya Soga; Yoshiki Kashimori
VISION RESEARCH, PERGAMON-ELSEVIER SCIENCE LTD, 49, 3, 337-347, Feb. 2009, Peer-reviwed, The ability to group Visual stimuli into meaningful categories is a fundamental cognitive process. Several experiments have been made to investigate the neural mechanism of visual categorization task. Although experimental evidence is known that prefrontal cortex (PFC) and inferior temporal cortex (ITC) sensitively respond in categorization task, little is known about the functional role of interaction between PFC and ITC in categorization task. To address this issue, we present a model, which performs categorization via an interaction between ITC, PFC, and posterior parietal (PP). Using the model, we show here that the functional connections of synapses between neurons in these areas are organized by the learning depending on a reward that is given only by correct behaviors for the task. We also show that the feedback from PFC to ITC allows the sensitivity enhancement of the ITC neurons encoding the object features critical for the task, and the feedback from PFC to PP works as a spatial attention required for finding object feature critical for the task. The model seems to be comparable with experimental data about categorization. (c) 2008 Elsevier Ltd. All rights reserved.

International conference proceedings, English - Spatiotemporal burst coding for extracting features of spatiotemporally varying stimuli
Kazuhisa Fujita; Yoshiki Kashimori; Takeshi Kambara
BIOLOGICAL CYBERNETICS, SPRINGER, 97, 4, 293-305, Oct. 2007, Peer-reviwed, Encoding features of spatiotemporally varying stimuli is quite important for understanding the neural mechanisms of various sensory coding. Temporal coding can encode features of time-varying stimulus, and population coding with temporal coding is adequate for encoding spatiotemporal correlation of stimulus features into spatiotemporal activity of neurons. However, little is known about how spatiotemporal features of stimulus are encoded by spatiotemporal property of neural activity. To address this issue, we propose here a population coding with burst spikes, called here spatiotemporal burst (STB) coding. In STB coding, the temporal variation of stimuli is encoded by the precise onset timing of burst spike, and the spatiotemporal correlation of stimuli is emphasized by one specific aspect of burst firing, or spike packet followed by silent interval. To show concretely the role of STB coding, we study the electrosensory system of a weakly electric fish. Weakly electric fish must perceive the information about an object nearby by analyzing spatiotemporal modulations of electric field around it. On the basis of well-characterized circuitry, we constructed a neural network model of the electrosensory system. Here we show that STB coding encodes well the information of object distance and size by extracting the spatiotemporal correlation of the distorted electric field. The burst activity of electrosensory neurons is also affected by feedback signals through synaptic plasticity. We show that the control of burst activity caused by the synaptic plasticity leads to extracting the stimulus features depending on the stimulus context. Our results suggest that sensory systems use burst spikes as a unit of sensory coding in order to extract spatiotemporal features of stimuli from spatially distributed stimuli.
Scientific journal, English - A functional role of interaction between IT cortex and PF cortex in visual categorization task
Yoshiki Kashimori; Yu Ichinose; Kazuhisa Fujita
NEUROCOMPUTING, ELSEVIER SCIENCE BV, 70, 10-12, 1813-1818, Jun. 2007, Peer-reviwed, The ability to group visual stimuli into meaningful categories is a fundamental cognitive process. Some experiments are made to investigate the neural mechanism of visual categorization. Although experimental evidence is known that prefrontal cortex (PFC) and inferior temporal cortex (ITC) neurons sensitively respond in categorization task, little is known about the role of interaction between ITC and PFC in categorization task that gives the category boundaries in relation to behavioral consequences. To address this issue, we propose a functional model of visual system in which categorization task is achieved based on functional roles of ITC and PFC. The functional role of ITC is to represent features of object parts, based on different resolution maps in early visual system such as V1 and V4. In ITC, visual stimuli are categorized by the similarity based on the features of object parts. The PFC neurons combine the information about feature and location of object parts, and generate a working memory of the object information relevant to the categorization task. The synaptic connections between ITC and PFC are learned so as to achieve the categorization task. The feedback signals from PFC to ITC enhance the sensitivity of ITC neurons that respond to the features of object parts critical for the categorization task. In the present study, we present a neural network model, which makes categories of visual objects depending on categorization task. We investigated the neural mechanism of the categorization task of line drawings of faces used by Sigala and Logothetis (N. Sigala, N.K. Logothetis, Visual categorization shapes feature selectivity in the primate temporal cortex, Nature 415 (2002) 318-320). Using this model we show that ITC represents similarity of face images based on the information of the resolution maps in V1 and V4. We also show that PFC generates a working memory state, in which only the information of face features relevant to the categorization task are sustained. It is further shown that the feedback connections from PFC to ITC may play an important role in extracting the diagnostic features of visual images in the categorization task. (c) 2006 Elsevier B.V.

K Fujita; Y Kashimori
NEUROCOMPUTING, ELSEVIER SCIENCE BV, 69, 10-12, 1206-1210, Jun. 2006, Peer-reviwed, To investigate the mechanism of sensory coding of spatiotemporally varying stimuli, we study the population coding of receptor network in electrosensory system. Weakly electric fish use amplitude modulations of their self-generated electric organ discharge (EOD AM) to detect distance and size of an object such as prey. We developed a model of fish by which we calculate numerically the spatiotemporal patterns of electric field around the fish body, and made a model of electroreceptor network. We showed previously that the information of object distance and size are represented by a combination of two characteristic features of EOD AM, the maximum amplitude and half-maximum width of EOD AM. We show here that the information of object distance and its size are encoded as synchronous firing of receptor network, leading to a reliable encoding of the two features of EOD AM in target neurons to which the receptors project, through a rapid synaptic integration of the receptor outputs. We further show that an optimal distribution of receptor sensitivity to EOD stimuli may provide a significant change of the two EOD AM features depending on object distance. (c) 2006 Elsevier B.V.

Scientific journal, English - A role of synchronicity of neural activity based on dynamic plasticity of synapses in encoding spatiotemporal features of electrosensory stimuli

MATHEMATICAL BIOSCIENCES, ELSEVIER SCIENCE INC, 201, 1-2, 113-124, May 2006, Peer-reviwed, It is quite important for investigation of sensory mechanism to understand how dynamical property of neurons is used for encoding the feature of spatiotemporally varying stimuli. To consider concretely the problem, we focus our study on electrosensory system of a weakly electric fish. Weakly electric fish generate electric field around their body using electric organ discharge (EOD) and accurately detect the location of an object through the modulation of electric field induced by the object. We made a neural network model of electrosensory lateral-line lobe (ELL). Here we show that the features of EOD modulation depending specifically distance and size of an object are encoded into the timing of burst firing of ELL neurons. These features can be represented by the spatial area of synchronous burst firing and the interburst interval in the ELL network. We show that short-term changes of excitatory and inhibitory synapses, induced by efferent signals, regulate the ELL activity so as to effectively encode the features of EOD modulation.

International conference proceedings, English - Behavior pattern (innate action) of individuals in fish schools generating efficient collective evasion from predation
M Zheng; Y Kashimori; O Hoshino; K Fujita; T Kambara
JOURNAL OF THEORETICAL BIOLOGY, ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 235, 2, 153-167, Jul. 2005, Peer-reviwed, The schooling of fishes is one typical animal social behavior. One primary function of fish school is to protect members when attacked by predators. One main way that the school reduces the predator's chance of making a successful kill is to confuse the predator as it makes its strike. This may be accomplished by collective evasion behaviors organized through integration of motions of individual fish made based on their innate actions (behavior patterns). In order to investigate what kind of behavior pattern of individuals can generate the efficient collective evasion of a school, we present a model of evasion behavior pattern which consists of three component behavior patterns, schooling, cooperative escape, and selfish escape behavior patterns and the rule for choice of one among them with proper timing. Each fish determines its movement direction taking into account simultaneously three kinds of elemental motions, mimicking its neighbors, avoiding collisions with its nearest neighbors, and escaping from an approaching predator. The weights of three elemental motions are changed depending on which component behavior pattern the fish carries out. The values of the weights for three component behavior patterns can be definitively determined under the condition that the collective evasion of the school becomes the most efficient, that is, the probability that any member is eaten by the predator becomes minimum.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 65, 219-228, Jun. 2005, Peer-reviwed, We present a functional model of form pathway in visual cortex based on the predictive recognition scheme, in which feedback image signals predicted from the memory system are compared with the feedforward image signals from the retina. We propose the functional roles of three kinds of spatial resolution maps in predictive perception of object form. The broad resolution map is used to categorize visual image based on the outline of the object and to choose the prediction image in the memory system based on the categorization. The middle resolution map is used for more detailed categorizations and for focusing prediction range. The fine resolution map is used to compare the feedforward image of a part of the object with the image predicted. (c) 2004 Elsevier B.V. All rights reserved.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 65, 243-251, Jun. 2005, Peer-reviwed, Sensory systems utilize dynamical response properties of neurons to extract features of spatiotemporally varying stimuli. We propose a dynamic population coding of sensory stimuli in which the stimulus features are encoded into a spatiotemporal firing pattern of neuron population. Using electrolocation of weakly electric fish as a model system, we study how the spatiotemporal features of electric field modulated depending on the distance and size of an object are encoded into the spatial distribution and time interval between burst spikes of neuron population. We showed that the information about distance and size of object are represented as a function of the spatial area of and time interval between the synchronous firing of neuron population in a higher nucleus.

BIOSYSTEMS, ELSEVIER SCI LTD, 76, 1-3, 33-42, Aug. 2004, Peer-reviwed, We present a functional model of form pathway in visual cortex based on predictive coding scheme, in which the prediction is compared with feedforward signals filtered by two kinds of spatial resolution maps, broad and fine resolution map. We propose here the functional role of the prediction and of the two kinds of resolution maps in perception of object form in visual system. The prediction is represented based on memory of dynamical attractors in temporal cortex, categorized by an elemental figure in posterior temporal cortex. The prediction is generated by the feedforward signals of main neurons in broad resolution maps of V-1 and V-4, and then is compared with the feedforward signals of main neurons in fine resolution map of V-1 and V-4.

Scientific journal, English - A neural mechanism for detecting the distance of a selected target by modulating the FM sweep rate of biosonar in echolocation of bat

BIOSYSTEMS, ELSEVIER SCI LTD, 76, 1-3, 55-64, Aug. 2004, Peer-reviwed, Most species of bats making echolocation use frequency modulated (FM) ultrasonic pulses to measure the distance to targets. These bats detect with a high accuracy the arrival time differences between emitted pulses and their echoes generated by targets. In order to clarify the neural mechanism for echolocation, we present neural model of inferior colliculus (IC), medial geniculate body (MGB) and auditory cortex (AC) along which information of echo delay times is processed. The bats increase the downward frequency sweep rate of emitted FM pulse as they approach the target. The functional role of this modulation of sweep rate is not yet clear. In order to investigate the role, we calculated the response properties of our models of IC, MGB, and AC changing the target distance and the sweep rate. We found based on the simulations that the distance of a target in various ranges may be encoded the most clearly into the activity pattern of delay time map network in AC, when the sweep rate of FM pulse used is coincided with the observed value which the bats adopt for each range of target distance.

ICONIP'02: PROCEEDINGS OF THE 9TH INTERNATIONAL CONFERENCE ON NEURAL INFORMATION PROCESSING, NANYANG TECHNOLOGICAL UNIV, 20-24, 2002, Peer-reviwed, The sound localization of barn owl with respect to horizontal and vertical direction is made based on analysis of the interaural differences in arrival time and intensity of sound, respectively The neural information processing of detection of interaural intensity difference (IID) is made on the neural pathway parallel with the pathway of interaural time difference (ITD) detection before both the signals arrive at the shell of central nucleus of the inferior colliculus (ICc shell). We have presented a neural model of ITD detection pathway (Inoue et al, Neurocomputing 2001, vol.38-40,pp.675-682). In the present paper, we present a neuronal model of the nucleus ventralis lemnisci lateralis pars posterior (VLVp) in which the signals of sound intensities coming from both the ears are first combined to be compared with each other. We clarify the functional role of mutual inhibitory connections between both VLVps observed experimentally in detection of IID. Outputs of IID sensitive neurons in both VLVps are projected bilaterally to ICc shell and the connections are inihibitory, whereas outputs of HD sensitive neurons in ICc core projected to ICc shell are excitatory. It is shown using our neuronal models of VLVps, ICc core, and ICc shell that the neural map, in which ITD and IID are represented along the axes perpendicular mutually, can be generated in ICc shell by the excitatory inputs from ICc core and the inhibitory inputs from bilateral VLVps, as observed experimentally We also show dig the firing rate of ICc shell neuron are well represented by a suppressive multiplication of ITD and IID inputs.
International conference proceedings, English - Role of feedback signals to hindbrain in discriminating between two objects in electrolocation
Y Kashimori; E Murase; MH Zheng; T Kambara
ICONIP'02: PROCEEDINGS OF THE 9TH INTERNATIONAL CONFERENCE ON NEURAL INFORMATION PROCESSING, NANYANG TECHNOLOGICAL UNIV, 30-34, 2002, Peer-reviwed, In order to clarify the neuronal mechanism by which the weakly electric fish discriminates between two objects presented nearby the fish body, we propose a model of electrosensory system including the feedforward signals from receptors and the feedback signals from higher nuclei. The distortion of electric organ discharge (EOD), induced by two objects, were calculated by the model of fish body. Here we show that the information relevant to each object is roughly separated by the synchronicity of burst patterns evoked on electrosensory lateral-line lobe(ELL) map. The functional roles of feedback signals to ELL are to facilitate the temporal separation of burst patterns evoked on ELL map, and to amplify selectively the burst pattern relevant to an attentive object.

ICONIP'02: PROCEEDINGS OF THE 9TH INTERNATIONAL CONFERENCE ON NEURAL INFORMATION PROCESSING, NANYANG TECHNOLOGICAL UNIV, 144-148, 2002, Peer-reviwed, We present a functional model of V4 area in visual cortex based on predictive coding scheme, in which the prediction is compared with three kinds of images corresponding to three kinds of image representations which are projected through the filters with three different sizes of spatial resolutions. The prediction is represented as a combination of elemental figures. These representations are generated by the response property of main neurons in VI and V4 areas that the main neurons respond selectively to a limited band of frequencies of spatial brightness distribution. We propose the functional role of elemental figures in invariant perception of object form in visual cortex.

ICONIP'02: PROCEEDINGS OF THE 9TH INTERNATIONAL CONFERENCE ON NEURAL INFORMATION PROCESSING, NANYANG TECHNOLOGICAL UNIV, 1941-1945, 2002, Peer-reviwed, To investigate the problem how and why most members in a primeval society become using vocal signal to represent non-substantial matters such as actions, we present a simple model of communication in which speakers use vocal signals and gestures. Each desire of speaker is represented by expression network. Every speaker expresses his or her desire by vocal signals and gestures. Then, any speaker's desire is expressed in a three step signal. When every hearer communicates with a speaker, the hearer receives speaker's signal by his and her own hearing neural network. At the beginning of evolutional process, the correspondence relation between desire and signal is different for different speaker. Whether the common relations are evolved in the society or not depend mainly on the number of temporally preserving neurons in the network and reward of communication.
International conference proceedings, English - A model describing collective behaviors of pedestrians with various personalities in danger situations
MH Zheng; Y Kashimori; T Kambara
ICONIP'02: PROCEEDINGS OF THE 9TH INTERNATIONAL CONFERENCE ON NEURAL INFORMATION PROCESSING, NANYANG TECHNOLOGICAL UNIV, 2083-2087, 2002, Peer-reviwed, We present a model describing motions of individual pedestrians to study collective behaviors of pedestrians in various situations such as normal or emergency situations. Each individual pedestrian has ability to decide own desired action depending on circumstances and own personality. In the present work the personality of pedestrian is expressed as patient and impatient character. The main frame of the present model is constructed based on the social force model, and the individual ability to decide own desired action is represented by the counterpropagation neural network. The combination of neural network and dynamic model makes motions of pedestrians more natural and reliable in various situations. It has been shown from the computer simulation of passing of many pedestrians through a road that there exists an optimal ratio of patient person's number to impatient person's number for the passage time and amenity of pedestrians.
International conference proceedings, English - A hierarchical dynamical map as a basic frame for cortical mapping and its application to priming
O Hoshino; S Inoue; Y Kashimori; T Kambara
NEURAL COMPUTATION, M I T PRESS, 13, 8, 1781-1810, Aug. 2001, Peer-reviwed, A hierarchical dynamical map is proposed as the basic framework for sensory cortical mapping. To show how the hierarchical dynamical map works in cognitive processes, we applied it to a typical cognitive task known as priming, in which cognitive performance is facilitated as a consequence of prior experience. Prior to the priming task, the network memorizes a sensory scene containing multiple objects presented simultaneously using a hierarchical dynamical map. Each object is composed of different sensory features. The hierarchical dynamical map presented here is formed by random itinerancy among limit-cycle attractors into which these objects are encoded. Each limit-cycle attractor contains multiple point attractors into which elemental features belonging to the same object are encoded. When a feature stimulus is presented as a priming cue, the network state is changed from the itinerant state to a limit-cycle attractor relevant to the priming cue. After a short priming period, the network state reverts to the itinerant state. Under application of the test cue, consisting of some feature belonging to the object relevant to the priming cue and fragments of features belonging to others, the network state is changed to a limit-cycle attractor and finally to a point attractor relevant to the target feature. This process is considered as the identification of the target. The model consistently reproduces various observed results for priming processes such as the difference in identification time between cross-modality and within-modality priming tasks, the effect of interval between priming cue and test cue on identification time, the effect of priming duration on the time, and the effect of repetition of the same priming task on neural activity.
Scientific journal, English - A neural mechanism of hyperaccurate detection of phase and delay in the jamming avoidance response of weakly electric fish
Y Kashimori; S Inoue; T Kambara
BIOLOGICAL CYBERNETICS, SPRINGER-VERLAG, 85, 2, 117-131, Aug. 2001, Peer-reviwed, The weakly electric fish Eigenmannia can detect the phase difference between a jamming signal and its own signal down to 1 mus. To clarify the neuronal mechanism of this hyperaccurate detection of phase difference, we present a neural network model of the torus of the midbrain which plays an essential role in the detection of phase advances and delays. The small-cell model functions as a coincidence detector and can discriminate a time difference of more than 100 mus. The torus model consists of laminae 6 and 8. The model of lamina 6 is made with multiple encoding units, each of which consists of a single linear array of small cells and a single giant cell. The encoding unit encodes the phase difference into its spatio-temporal firing pattern. The spatially random distribution of small cells in each encoding unit improves the encoding ability of phase modulation. The neurons in lamina 8 can discriminate the phase advance and delay of jamming electric organ discharges (EODs) compared with the phase of the fish's own EOD by integrating simultaneously the outputs from multiple encoding units in lamina 6. The discrimination accuracy of the feature-detection neurons is of the order of 1 mus. The neuronal mechanism generating this hyperacuity arises from the spatial feature of the system that the innervation sites of small cells in different encoding units are distributed randomly and differently on the dendrites of single feature-detection neurons. The mechanism is similar to that of noise-enhanced information transmission.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 38, 1341-1348, Jun. 2001, Peer-reviwed, To clarify the neural mechanism by which weakly electric fish discriminates a sign of frequency difference (Df) between its own electric organ discharge (EOD) and the neighbor's, we proposed the binding mechanism of amplitude and phase information in lamina 8 of the torus and the integration mechanism in nucleus electrosensoris (nE). The binding can eliminate the wrong signals about the sign of Df. When the modulation of EOD signal is extremely small, the nE network can detect a sign of Df by the dynamical integration which is made by the synchronous firings of nE neurons induced by noises.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 38, 1349-1357, Jun. 2001, Peer-reviwed, We address the question of how the fish recognizes the location of objects at a given position, independently of the electric properties of objects, although the distortion pattern of electric field is varied depending on the electric property. To know how the electric field generated by fish's electric organ discharge (EOD) is spatially and temporally distorted by resistive and capacitive objects, we calculated the electric field using a reasonable model of fish body. P and T electroreceptors distributed on the fish body surface respond to the amplitude and phase modulations of EOD, respectively, and propagate their output signals to electrosensory lateral-line lobe (ELL) and torus semicircularis (Ts), respectively. As the first step to clarify the neural mechanism of electrolocation, we made a neural network model of electrosensory system consisting of electroreceptors, afferent nerves, ELL, and TS, and investigated how the amplitude and phase modulations are encoded in ELL and TS, respectively.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 38, 705-712, Jun. 2001, Peer-reviwed, To clarify the neuronal mechanism of navigation behavior, we propose a model of total system of neural network for a rodent to accomplish a navigation task.

We show the neuronal mechanism by which these maps are self-organized during the navigation task, and the functional roles of these maps in the achievement of the task. In the task dependent map, the important places in the task field are memorized as dynamical attractors of the network activity, and the task is accomplished by learning temporary the correlation between dynamical attractors, depending on the input from the value judgement system and on the strength of attention.

8TH INTERNATIONAL CONFERENCE ON NEURAL INFORMATION PROCESSING, VOLS 1-3, PROCEEDING, FUDAN UNIV PRESS, 199-204, 2001, Peer-reviwed, Weakly electric fish generates electric field around its body using electric organ discharge and can accurately detect the location of an object using the modulation of electric field induced by an object. Objects with electric properties different from those of the surrounding water distort the electric field around fishy body, depending on the size, distance and electric properties of objects. It is not clear yet how the fish recognizes the properties of an object such as its electric property,, location and size based on its electric image. As the first step to clarify, the neuronal mechanism of electrolocation, we developed a model of fish body by which we describe numerically the spatio-temporal patterns Of electric field around the fish body. Me made also neural models of electroreceptors distributed on the fish body and of electrosensory lateral line lobe(ELL) to investigate what kinds of information of electric field distorted by, an object they detect. The models reproduce qualitatively the experimental results about the detections of size, distance, and moving directions of an object. Me show that the ability of ELL neuron to detect the direction of object movement parallel to the fish body is generated by the spatially, inhomogeneous pattern of electric field along the fish body, from head to tail, which is induced originally by the electric organs in the tail of fish.

情報処理学会論文誌：数理モデル化と応用, Information Processing Society of Japan (IPSJ), 42, 14, 134-149, 2001, Peer-reviwed, A simulation model of collective motion of a fish group was presented to investigate the role of allelomimesis of fish individual in emergence of dynamically stable schooling behaviors. The present model was formulated based on the individual decision-making approach. Allelomimesis, doing what your neighbors do, was considered as the essential tactic of decision-making by which coherent collective behaviors such as schooling are generated. Besides the allelomimetic actions of individuals, the collision avoidance actions are also another essential tactic. As a measure of the tactic of decision-making, the ratio of contributions of allelomimetic and avoidance actions is adopted. It was investigated changing systematically value of the contribution ratio how and to what extent fish individuals mimic their neighbors so that the fish group shows the schooling behaviors. It was shown that the schooling behaviors generated using the optimal values of the ratio correspond to a self-organized critical state. The main purpose of the present modeling is to investigate whether the tactic of individual decision-making suited to generate good schooling behaviors works well also in maintaining dynamical stability of the fish school under emergent affairs. Emergent splitting of a school into two groups and flash expansion of a school were used as the emergent affairs. The extent of dynamical stability of a school was evaluated using two kinds of measures, the recovery time period and the critical distance of splitting or expansion. It was found that the tactic suitable for schooling generates the dynamically stable response of the school to emergent affairs.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 32, 809-816, Jun. 2000, Peer-reviwed, A hierarchical dynamical map is proposed to be the basic frame of sensory cortical maps. We modeled a cortical neural network and carried out a cognitive process known as "priming" in which the identification of a stimulus is facilitated as a consequence of prior exposure to it. We demonstrate that even a single cortical map can have a hierarchical function based on the dynamics of the cortical network. It has also been demonstrated that the hierarchical dynamical map plays an essential role in binding different sensory modalities simultaneously present in the same visual scene.

We propose a neural mechanism by which the bat may detect the time differences independently of the target velocity using FM ultrasonic pulses. The neural processing model presented consists of the networks in MGB for calculating the temporal correlation between pulse and echo for each frequency and the network of AC for integrating the calculated results over the frequency range used by bat. We found that the key factor generating the detection independent of target velocity is the value of frequency modulation rate of about 6 kHz. (C) 2000 Published by Elsevier Science B.V.

To clarify the neural mechanism accomplishing the hyperaccurate discrimination, we present a neural model of the torus. The time difference between afferent nerve spikes arising from different sites on the body surface is detected by the two-dimensional array of small cells in the torus. The phase advance and delay are detected by integrating the outputs of small cells. The hyperaccurate detection is accomplished by the stochastic resonance induced by the spatio-temporal integration of the outputs including noises. (C) 2000 Elsevier Science B.V. All rights reserved.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 32, 863-869, Jun. 2000, Peer-reviwed, In order to clarify a role of depolarization timing-dependent learning in suppression of reafferent signals of weakly electric fish, we made a neural network model of electrosensory lateral-line lobe (ELL) which consists of basilar pyramidal (bp) cells. We propose a learning rule depending on temporal correlation between pre- and post-synaptic inputs. It is shown that the learning depending on the timings of pre- and postsynaptic depolarization plays an essential role in the discrimination of the synchronous signals from noisy background descending signals. The active property of the apical dendrite, by which the depolarization of soma reliably propagates backward from soma to dendrite, is necessary to detect the temporal correlation between the ascending and descending signals.

NEUROCOMPUTING, ELSEVIER SCIENCE BV, 26-7, 395-401, Jun. 1999, Peer-reviwed, Barn owl can detect the arrival time disparity of binaural input sound which is of the order of 10 mu s We proposed that this hyperacuity for detection of the disparity is accomplished through a combination of two kinds of functional contributions. One comes from the functional structure of a neural unit for coincidence detection, and the other comes from a functional structure of a network constructed with the: units. The network model of nucleus laminaris is made based on Jeffress' model. The hyperacuity has been achieved by positively including noises in the input signals. (C) 1999 Elsevier Science B.V.

We show that the selective tuning comes from the tuning property of single bp cell and the synchronization of activity among the cells connected with the electric synapse between them.

ICONIP 1999, 6th International Conference on Neural Information Processing - Proceedings, Institute of Electrical and Electronics Engineers Inc., 2, 465-470, 1999, Peer-reviwed, We have made a simulation model of fish motion to clarify the essential mechanism of fish schooling. Though each fish does not know the behavior of the entire group and there is no leader in the group, they gather and move together, based on the local interaction between fish individuals. By calculating the power spectra of temporal variations of direction and expanse of the school, we show that the school behavior is a type of self-organized critical phenomenon. We are concerned especially with group intelligence of fish schools. In order to investigate what the group intelligence is and how it emerges, using the model we study as a first step response behavior of fish groups induced by attacks of a predator under various situations, because fish groups seem to display their group intelligence to the utmost ability under such a serious situation.

ICONIP 1999, 6th International Conference on Neural Information Processing - Proceedings, Institute of Electrical and Electronics Engineers Inc., 2, 471-476, 1999, Peer-reviwed, In order to study how the cognitive maps are generated and function to drive appropriate motor activities, we consider the behavior in which a honey bee forages about to collect honey. We approach a solution to the problem by reconstructing the neural system, realizing the foraging trips with reasonable neural network models. We present a neural model of the control system for the foraging trips, which consists of a sequence route map, cognitive spatial map, and matching recognition map. The model reproduces reasonably several observed behaviors of honeybees relevant to the foraging trips.

ICONIP 1999, 6th International Conference on Neural Information Processing - Proceedings, Institute of Electrical and Electronics Engineers Inc., 2, 477-482, 1999, Peer-reviwed, Most species of bats making echolocation use frequency modulated (FM) ultrasonic pulses to measure the distance to targets such as flying insects. These bats detect with a high accuracy the arrival time differences between emitted pulses and their echos generated by targets, even though the targets are moving. We propose a neural mechanism by which the bat may detect the time differences independently of the target velocity using FM ultrasonic pulses. The neural processing model presented consists of the networks for calculating the temporal correlation between pulse and echo for each frequency and network for integrating the calculated results over the frequency range used by the bat. We found that the key factor generating the detection independent of target velocity is the value of frequency modulation rate.

Y Kashimori; H Funakubo; T Kambara
BIOPHYSICAL JOURNAL, BIOPHYSICAL SOCIETY, 75, 4, 1700-1711, Oct. 1998, Peer-reviwed, To study a role of syncytium structure of sensory receptor systems in the detection of weak signals through stochastic resonance, we present a model of a receptor system with syncytium structure in which receptor cells are interconnected by gap junctions. The apical membrane of each cell includes two kinds of ion channels whose gating processes are described by the deterministic model. The membrane potential of each cell fluctuates chaotically or periodically, depending on the dynamical state of collective channel gating. The chaotic fluctuation of membrane potential acts as internal noise for the stochastic resonance. The detection ability of the system increases as the electric conductance between adjacent cells generated by the gap junction increases. This effect of gap junctions arises mainly from the fact that the synchronization of chaotic fluctuation of membrane potential between the receptor cells is strengthened as the density of gap junctions is increased.
Scientific journal, English - An olfactory recognition model based on spatio-temporal encoding of odor quality in the olfactory bulb
O Hoshino; Y Kashimori; T Kambara
BIOLOGICAL CYBERNETICS, SPRINGER VERLAG, 79, 2, 109-120, Aug. 1998, Peer-reviwed, In order to study the problem how the olfactory neural system processes the odorant molecular information for constructing the olfactory image of each object, we present a dynamic model of the olfactory bulb constructed on the basis of well-established experimental and theoretical results. The information relevant to a single odor, i.e. its constituent odorant molecules and their mixing ratios, are encoded into a spatio-temporal pattern of neural activity in the olfactory bulb, where the activity pattern corresponds to a limit cycle attractor in the mitral cell network. The spatio-temporal pattern consists of a temporal sequence of spatial firing patterns: each constituent molecule is encoded into a single spatial pattern, and the order of magnitude of the mixing ratio is encoded into the temporal sequence. The formation of a limit cycle attractor under the application of a novel odor is carried out based on the intensity-to-time-delay encoding scheme. The dynamic state of the olfactory bulb, which has learned many odors, becomes a randomly itinerant state in which the current firing state of the bulb itinerates randomly among limit cycle attractors corresponding to the learned odors. The recognition of an odor is generated by the dynamic transition in the network from the randomly itinerant state to a limit cycle attractor state relevant to the odor, where the transition is induced by the short-term synaptic changes made according to the Hebbian rule under the application of the odor stimulus.

NEURAL NETWORKS, PERGAMON-ELSEVIER SCIENCE LTD, 10, 8, 1375-1390, Nov. 1997, Peer-reviwed, A basic frame, based on which certain features of sensory stimuli can be extracted systematically in a distributed coding scheme, has not been clarified yet. This paper proposes that the basic frame can be a dynamical map represented by itinerancy among attractors. Features of entities are encoded by attractors of neural networks. Relations between the features in each modality are mapped on dynamical links between the attractors in each network relevant to each modality. The itinerant states, in which the network dynamic state itinerates chaotically or cyclically among the attractors, can work as dynamical maps. The recognition of features is carried out by a phase transition from an itinerant state to a constituent attractor. The phase transition is induced by a short-term synaptic change based on the Hebbian rule under application of a relevant stimulation. A theta-like global oscillation is necessary for self-organized formation of the chaotically itinerant state. (C) 1997 Elsevier Science Ltd.
Scientific journal, English - A neural mechanism for hyperacuity in jamming avoidance response of electric fish Eigenmannia
Y Kashimori; T Kambara
1997 IEEE INTERNATIONAL CONFERENCE ON NEURAL NETWORKS, VOLS 1-4, I E E E, 1, 332-337, 1997, Peer-reviwed, Eigenmannia can detect the phase difference (Delta t omega) of the order of Delta t = 1 mu sec between jamming signal and its own signal. We propose that this hyperacuity is accomplished through a combination of two kinds of functional contributions. One comes from a functional structure of neural unit for coincidence detection, and the other results from a functional structure of network consisting of the units. The network model is made based on the Jefferess model, but each unit is connected with nearest neighboring units through excitatory synapse and with the other neighbors through inhibitory synapse. The netwok can detect a tenth of the magnitude of the difference which the single unit can do. The unit of coincidence detector consists of a neuron with active dendrites which receives inputs through two excitatory connections and one inhibitory synapse. A single unit can detect the difference of the order of 10 mu sec.

1997 IEEE INTERNATIONAL CONFERENCE ON NEURAL NETWORKS, VOLS 1-4, I E E E, 1, 318-323, 1997, Peer-reviwed, We studied the dependence of response property of the syncytium consisting of receptor cells on dynamics of collective ion channel gating in the cells, which are periodic, stably chaotic, and unstably chaotic. The dynamics of unstable chaos state synchronizes the potential variation of all receptor cells in the syncytium induced by external stimuli. The syncytium system in the stable and unstable chaos states can detect a weak periodic input signal without assistance of any level of noise.
International conference proceedings, English - Feature extraction from mixed odor stimuli based on spatio-temporal representation of odors in olfactory bulb
O Hoshino; Y Kashimori; T Kambara
1997 IEEE INTERNATIONAL CONFERENCE ON NEURAL NETWORKS, VOLS 1-4, I E E E, 1, 344-349, 1997, Peer-reviwed, In order to clarify the neural mechanism by which olfactory features are extracted from mixed odor stimuli, we present a model in which each constituent molecule of odor is encoded into a spatial firing pattern in the olfactory bulb and the order of mixing ratio of the molecule is coded into the order of temporal sequence of the spatial patterns. That is, quality and intensity of each odor are encoded into a limit cycle attractor in the dynamical network of olfactory bulb. It depends on types of temporal fluctuation of constituent odor intensity what kinds of limit cycle attractors are formed under application of mixed odor stimulation. When the fluctuation of each odor in the mixture is independent of those of the other odors, each odor is encoded separately into each attractor. However, some odors with coherent fluctuation are encoded into a single limit cycle attractor, that is, recognized as a single feature.
International conference proceedings, English - Hierarchical classification of odor quality based on dynamical property of neural network of olfactory cortex
T Oyamada; Y Kashimori; T Kambara
1997 IEEE INTERNATIONAL CONFERENCE ON NEURAL NETWORKS, VOLS 1-4, I E E E, 1, 586-590, 1997, Peer-reviwed, We study a mechanism of odor classification in olfactory cortex based on the hypothesis that components of an odor and their mixing ratio ave encoded into a temporal sequence of spatial activity patterns, that is, a limit cycle attractor in olfactory bulb. We present a functional network model of olfactory cortex which consists of three, rostral, middle, and caudal, compartments.
When a temporal sequence of spatial firing patterns is injected from the olfactory bulb to the network model, neural activity states of rostral, middle and caudal compartments are fixed to the spatial patterns corresponding to the strong, middle and weak components, respectively. Each compartment recognizes a relevant odorant component. An odor quality is recognized based on the combination of three fixed patterns. The stronger the mixing ratio of a component is, the earlier the component is recognized. This is a hierarchical classification.
International conference proceedings, English - Model of P- and T-electroreceptors of weakly electric fish
Y Kashimori; M Goto; T Kambara
BIOPHYSICAL JOURNAL, BIOPHYSICAL SOCIETY, 70, 6, 2513-2526, Jun. 1996, Peer-reviwed, To clarify the microscopic mechanisms by which P- and T-receptors encode amplitude modulation and zero crossing time of jamming signals, we present a model of P- and T-receptors based on their physiological and anatomical properties. The model consists of a receptor cell, supporting cells, and an afferent nerve fiber. The basal membrane of the receptor cell includes voltage-sensitive Ca2+ channels, Ca2+-activated K+ channels, and leak channels of Na+, K+, and Cl-. The driving force of potential change under stimulation is generated by the voltage-sensitive Ca2+ channels, and the suppressing force of the change is generated by Ca2+-activated K+ channels. It has been shown that in T-receptor cells the driving force is much stronger than the suppressing force, whereas in P-receptor cells the driving force is comparable with the suppressing force. The differences in various kinds of response properties between P- and T-receptors have been consistently explained based on the difference in the relative strengths of the driving and suppressing forces between P- and T-receptor cells. The response properties considered are encoding function, probability of firing of afferent nerve, pattern of damped oscillation, shape of tuning curves, values of the optimum frequency, and response latency.
