| Research Abstract |
The prefrontal cortex and the basal ganglia are considered to be related with temporal estimation. However, their functions remains unclear. We recorded single-unit activity from the brain regions while monkeys were performing a duration discrimination task. We found that, in the striatum, phasic(transient) activity with various time intervals from the cue onset, which was previously found in the prefrontal cortex. Furthermore, striatal neurons showed duration-responsive activity in the following delay periods.
