Outline of Final Research Achievements

Both the basal ganglia and cerebellum play roles in time perception and temporal control of movements. We trained monkeys to report the time interval by making eye movements, and compared neuronal activity in the striatum and the cerebellar nucleus. The time course of neuronal activity in the striatum strongly depended on the time interval to be reported, while that in the cerebellum did not. Effects of local application of neuroactive agents to the recording sites were also examined. Neuronal activity related to temporal prediction was also recorded in monkeys that attempted to detect single omission of repetitive audiovisual stimuli.
