Research Abstract

The dendritic signal propagating path formation system was studied by using of the discrete dynamics model based on a reaction-diffusion system. In this system dendritic path expands or shrinks depending on a history of signal propagation on the path. In this study this shrinking aspects was focused on. The variety of patterns of dendritic path and signal propagation patterns were investigated. As an extension of this system three-dimensional dendritic signal propagation path formation system was described.
In order to realize the dynamics in which path changes dynamically according to a signal propagation history, it is necessary that subtractive path reformation system with initial state of random network path connection, and it is important that adoption of a conservative quantity, like a source of path formation.
