| Outline of Final Research Achievements |
To uncover the functional interaction between prefrontal cortical areas, we have conducted simultaneous local-field-potential recordings from the monkeys performing a cognitively demanding task with frequent rule switches. We have also developed a projection-specific functional blockage method with virus vectors. In the recording experiments, the anterior cingulate sulcus area, principal sulcus area, and caudate head increased the power of activities in low-beta frequency band (~15Hz) at the initial fixation period of each trial and at the inter-trial interval, and these activities in the three regions were synchronized. The transient increase of the synchronized activities suggests that the three regions exchanged signals specifically in these time epochs.
