FIG. 3.

The basal ganglia system shows high specificity in correlational connectivity with the cortex. Motor and premotor cortex are most correlated with putamen and juxtaposing head of caudate nucleus (slice: z = 10). Prefrontal cortex is most correlated with caudate nucleus (slice: z = 10). Parietal and occipital cortex have weaker but seemingly specific correlations with parts of globus pallidus, mostly confined to the internal segment (slice: z = 2). Temporal cortex has weak correlations with parts of putamen (z = 0). Somatosensory (z = 10).
