| Outline of Final Research Achievements |
In the process of choosing and executing behavior it is suggested that the multiple areas in the frontal cortex and the basal ganglia play a crucial role. However, the underlying neural mechanisms in terms of functions and networks remain elusive. In the analysis of functions, we found a functional gradient within the frontal cortex. We also found that in making decisions the frontal cortex plays a primary role, while the basal ganglia are mainly involved in retrieving a decision made by other areas, such as the frontal cortex. Further, by comparing neurons in a cortical motor area and the thalamic reticular nucleus, a gateway in the cortico-basal ganglia network, and we found that this nucleus plays a role as an activity filter. In the analysis of networks, we found that a cortical area receives diverse inputs from multiple territories of the basal ganglia. Altogether, these results further revered functional and structural mechanisms underlying behavioral control.
