Chaotic itinerancy as a mechanism of irregular changes between synchronization and desynchronization in a neural network.

- I. Tsuda, H. Fujii, Satoru Tadokoro, T. Yasuoka, Y. Yamaguti
- Psychology, Medicine
- Journal of integrative neuroscience
- 1 June 2004

We investigate the dynamic character of a network of electrotonically coupled cells consisting of class I point neurons, in terms of a finite dimensional dynamical system. We classify a subclass of… Expand

Transitory behaviors in diffusively coupled nonlinear oscillators

- Satoru Tadokoro, Y. Yamaguti, H. Fujii, I. Tsuda
- Medicine, Computer Science
- Cognitive Neurodynamics
- 20 January 2011

We study collective behaviors of diffusively coupled oscillators which exhibit out-of-phase synchrony for the case of weakly interacting two oscillators. In large populations of such oscillators… Expand

Mathematical modeling for evolution of heterogeneous modules in the brain

- Y. Yamaguti, I. Tsuda
- Computer Science, Medicine
- Neural Networks
- 1 February 2015

Modular architecture has been found in most cortical areas of mammalian brains, but little is known about its evolutionary origin. It has been proposed by several researchers that maximizing… Expand

Spatial clustering property and its self-similarity in membrane potentials of hippocampal CA1 pyramidal neurons for a spatio-temporal input sequence

- Y. Fukushima, M. Tsukada, I. Tsuda, Y. Yamaguti, S. Kuroda
- Computer Science, Medicine
- Cognitive Neurodynamics
- 12 October 2007

To clarify how the information of spatiotemporal sequence of the hippocampal CA3 affects the postsynaptic membrane potentials of single pyramidal cells in the hippocampal CA1, the spatio-temporal… Expand

Transitory memory retrieval in a biologically plausible neural network model

- Hiromichi Tsukada, Y. Yamaguti, I. Tsuda
- Computer Science, Medicine
- Cognitive Neurodynamics
- 1 February 2013

A number of memory models have been proposed. These all have the basic structure that excitatory neurons are reciprocally connected by recurrent connections together with the connections with… Expand

A mathematical model for Cantor coding in the hippocampus

- Y. Yamaguti, S. Kuroda, Y. Fukushima, M. Tsukada, I. Tsuda
- Medicine, Mathematics
- Neural Networks
- 2011

Recent studies suggest that the hippocampus is crucial for memory of sequentially organized information. Cantor coding in hippocampal CA1 is theoretically hypothesized to provide a scheme for… Expand

Iterated function systems in the hippocampal CA1

- S. Kuroda, Y. Fukushima, Y. Yamaguti, M. Tsukada, I. Tsuda
- Mathematics, Medicine
- Cognitive Neurodynamics
- 1 September 2009

How does the information of spatiotemporal sequence stemming from the hippocampal CA3 area affect the postsynaptic membrane potentials of the hippocampal CA1 neurons? In a recent study, we observed… Expand

Modeling the Genesis of Components in the Networks of Interacting Units

- I. Tsuda, Y. Yamaguti, H. Watanabe
- Computer Science
- 2015

From the viewpoint of system development, we investigate how components emerge in a network system consisting of interacting units. We propose two mathematical models with ‘variational’ principles:… Expand

Self-Organization with Constraints - A Mathematical Model for Functional Differentiation

- I. Tsuda, Y. Yamaguti, H. Watanabe
- Computer Science, Mathematics
- Entropy
- 26 February 2016

This study proposes mathematical models for functional differentiations that are viewed as self-organization with external constraints. From the viewpoint of system development, the present study… Expand

Information flow in heterogeneously interacting systems

- Y. Yamaguti, I. Tsuda, Y. Takahashi
- Medicine, Computer Science
- Cognitive Neurodynamics
- 1 February 2014

Motivated by studies on the dynamics of heterogeneously interacting systems in neocortical neural networks, we studied heterogeneously-coupled chaotic systems. We used information-theoretic measures… Expand
