| Outline of Final Research Achievements |
In this study, we examined how cortical pyramidal neurons and interneurons encode information for motor functions in rats performing a behavioral task requiring do or do not execute a motor action intentionally. We analyzed multi-neuronal activity that was recorded from the forelimb areas of primary and secondary motor cortices through 16 or 32ch multichannel silicon probe(s) during their task performance. We found that basal spike properties and functional activity are very similar between these two motor areas, but the functional activity was more adaptive in the secondary motor cortex than the primary one. These observations suggest that the secondary motor cortex may be functionally differentiated to integrate motor information with internal state information for an adaptation to goal-directed behaviors.
