Outline of Final Research Achievements

Physarum plasmodium is a giant unicellular organism and performs information processing by using protoplasmic shuttle streaming. In this study, we regarded the intelligent beings as a model cell and suggested understanding of new order induced by an effect of local and/or global external stimulation or the local and/or global feedback. Specifically, (1) we suggested the reaction element using a electric circuit that simulated the behavior of the cell, (2) we revealed an emergence of the new function of the cell by giving periodic external stimulation and the frequency-dependent response, and (3) we understood the new order and function by local and/or global feedback effect in the reaction diffusion system.
