Research Abstract

This research consists of the following three sub-themes: [1] Intra-brain hetero-interactions, [2] hetero-coupled dynamical systems, [3] random dynamical systems. In [1], we established a network model of Hodgkin-Huxley type of neurons, based on which a dynamic associative memory was realized. This model was extended to a model for complex visual hallucination. In [2], we proposed a model for hetero-interactions of dynamical systems, and also a new learning algorithm. In [3], we found a new dynamical system embedded in the data of activity of place neurons in rat hippocampus, such that the probabilities of renewal of dynamics change in time. Furthermore, we proposed a new principle of self-organization as the second order, in which components or elements are differentiated under the constraints at a macroscopic level of system.
