Actualization of the signal-processing function by path reforming in a complicated network-like signal propagation media

利用基于反应扩散系统的离散动力学模型，研究了树枝状信号传播路径的形成系统。在该系统中，树枝状路径根据路径上的信号传播历史而扩展或收缩。在这项研究中，重点关注了这种收缩方面。研究了树枝路径和信号传播模式的变化。作为该系统的扩展，描述了三维树枝状信号传播路径形成系统，为了实现路径根据信号传播历史动态变化的动态，需要采用具有随机网络路径连接初始状态的减法路径重构系统，并且重要的是采用守恒量作为路径形成的源。

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.
