The Physarum plasmodium is a giant amoeboid cell, having no definite cell shape and size. This primitive organism is able to sense such environmental factors as chemicals, light, electric field, gravity, temperature, etc., to integrate these information, and to give rise a particular shapepossibly best suitedfor that environment. It is becoming clear that a primitive form of behavioral intelligence is hidden in these dynamic changes.
I will show lines of experimental evidence which shed light on the following questions.
(1) How does the chemical system bring about intelligence?
(2) How does the organism perceive a conflicting stimulus?
(3) How are the networks of veins characterized ?
In performing the above research, the interplay among different disciplines of science is necessary and fruitful.
