Outline of Final Research Achievements

Temporal monitoring and prediction of event timing are essential for behavioral control in daily life. In this study, we examined neuronal activity in the striatum and the cerebellar dentate nucleus in monkeys performing a variety of timing tasks. We also conducted behavioral experiments exploring the relationship between pupil diameter and subjective passage of time, neural mechanism of rhythm perception, and the capability of synchronized movements in nonhuman primates. Through these studies in the field of neuroscience, we could contribute to the advancement of The Science of Mental Time.
