Research has made considerable progress in describing the learning and motivational processes controlling goal-directed action and their related neural circuitry. Broadly this circuitry spans various regions within the corticostriatal-thalamic loop, within which specific structures mediate differentiable aspects of goal-directed learning and performance. These aspects include the acquisition of action-outcome contingencies, the encoding and retrieval or incentive value, the matching of that value to specific outcome representations, and finally the integration of this information for action selection. Information from each of the structures that mediate these processes converges on the striatum, with the posterior dorsomedial striatum in particular hypothesized to represent the neural locus of goal-directed action. Here we discuss evidence from rodent studies regarding the neural circuits mediating each of these individual processes before considering how they are integrated within the striatum for successful goal-directed action selection.
