Outline of Final Research Achievements

The cerebellum has been posited to involve time perception. Potential differences between sub-second and supra-second processing in this brain region were examined in this study, using a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS). This technique was adopted to reveal a ‘causality’ between the cerebellum and time perception. In the experiment, the cerebellar excitability was modulated by the anodal or cathodal tDCS, and the performance of time-relevant tasks before and after the stimulation was measured with psychophysical methods.
