摘要
Disruptions in dopamine transmission within the basal ganglia (BG) produce deficits in voluntary actions, that is, in the interface between cortically-generated goal representation and BG-mediated response selection. Under conditions of dopamine loss in humans and other annuals, responses are impaired when they require internal generation, but are relatively intact when elicited by external stimuli.
