| Outline of Final Research Achievements |
The plasmodium of the true slime mold Physarum Polysepharum is a large, single-celled amoeboid organism. This large organism extends its front for foraging. The slime mold can sense environmental information and change its behavior depending on the situations. For example, when the expanding front touches the wall, other part will start to move and become a new front in few minutes. It seems the slime mold transmits information from one side to another. However they do not have nerve system.
We made a mathematical model of the expanding slime mold to reveal their information processing. Our model reproduces fundamental characteristics of the front expanding, including change of direction. We found that the pressure of protoplasm plays a role as “information” in our model for change of moving direction.
