| Outline of Final Research Achievements |
Goal-oriented behavior is carried out with a definitive intention directed to an object such as food, prey and enemy. Since the behavior involves higher central nervous functions including attention and motivation, it is difficult in general to clarify its neurophysiological mechanism. This study, focused on the gripping action of chelipeds in crustaceans, aimed to examine if crustaceans could be trained to intentionally initiate gripping behavior in response to a visual cue and to analyze the neuronal mechanism underlying the initiation of such behavior by multiple unit recording techniques. The results demonstrated that functional units associated with the cue presentation or the behavioral initiation could be identified physiologically in an experimental protocol where the animal was instructed by the cue to initiate gripping behavior. Those units would provide an important clue for future research on the central nervous mechanism of goal-oriented behavior at the cellular level.
