| Research Abstract |
The plasmodium of the true slime mould, Physarum polycephalum, is a large amoeboid unicellular organism, which does not have any special organ for information processing, can behave properly in response to environmental changes and adapt successfully to the environment. The purpose of this project is to reveal the mechanism of the emergence of brain function in this organism by studying the dynamics of cell behaviors. Our results make clear how the plasmodium makes decision to environmental changes from the level of metabolic reaction driving the cell motility, to the control mechanism of the cell migration, and to the design principle of the cell morphology.
