Unlike Baxter's group, however, the NIMH researchers uncovered no changes in the caudate nucleus.
The study revealed reduced metabolic activity in the caudate nucleus and in the thalamus when the subjects were at rest (Clark et al.
Using ROI analysis the study demonstrated that in the cocaine abusers, but not in the control subjects, cocaine craving elicited by the videotapes resulted in increased blood flow in the amygdala and anterior cingulate cortex and decreased blood flow in the caudate nucleus and in the globus pallidus, which connects the striatum and the thalamus.

They showed that the associative or medial striatum (similar to most of the caudate nucleus in primates) is critical for the early, goal-directed stage of action learning, whereas the sensorimotor or lateral striatum (similar to the putamen in primates) is more critical for the later, more habitual stage (see figure 1).
