Neural Circuits for Action Selection

ByPaul Cisek, David Thura

We summarize neural evidence suggesting that action selection is determined in a network of cortical areas that prepare and execute actions, and review the potential roles played by the basal ganglia. We propose that correspondence between neural circuits and specific types of decisions can be achieved by considering how and when these circuits emerged in evolution and the behavioral innovations they conferred. We arrive at the hypothesis that the basal ganglia select a type of behavior by invigorating a cortical circuit specialized for a given type of action, while the specific targets and movements are selected within that cortical region.
