| Outline of Final Research Achievements |
We can stop a stopwatch in ten seconds with eyes closed. This suggests that our brain have timing function such as a “stopwatch”. Nonetheless, it is unclear how physical time is transformed into brain time. Temporal interval is a modality-independent physical attribute which can be perceived whether it is assigned to a visual, auditory or somatic stimulus. The frontal lobe receives inputs from multiple sensory systems and plays a role in integrating sensory information. It is therefore natural to speculate that the frontal lobe would participate in time perception and represent temporal attributes in some way. Monkeys were trained to discriminate between temporal durations associated with visual or auditory stimuli. Neuronal activity was recorded while the subjects were performing the task. We found various types neurons exhibiting phasic activity and sustained activity, and so on, which were associated with temporal processing from the prefrontal cortex and the premotor cortex.
