Abstract
A lot of researches try to realize a useful system in real world, which is mimicing from information processing system of living thing, especially animals. The features of information processing system of an animal are adaptability strong against disturbance, and autonomous emergency of an information processing rule, but there are many unknown portions about the mechanism yet. We reconstruct a dissociated culture system of neuronal network using the nerve cell taken out from the hippocampal region of a rat brain, and elucidate whether the information processing system can perform perception for the outer world and whether the origin of intelligence emerges in the system. For the first step, we applied feed-back stimulation into the living neuronal network. When the feed-back stimulation system detects synchronous action potentials at 2 recording sites simultaneously, it applies single stimulation. The feed-back stimulation evoked drastic change of spatiotemporal pattern of the activities of action potentials. The result suggested that the living neuronal network can perform modification of their own responding rules against outer world by interaction. Now we are developping a system for the living neuronal network interacting to outerworld mediated by miniature moving robot.
