| Research Abstract |
The survival of an organism can depend upon the direction in which it decides to move in response to changes in external conditions. In this project, we proposed mathematical models to elucidate mathematical mechanism of chemical reaction network for adaptive behavior. It was found that the proposed model describes a physicochemical mechanism of coupling between the local modulation of frequency and the global transport of protoplasmic mass. The decision process was clarified from a rheological point of view.
