One sample t-tests for resting-state functional connectivity with bilateral caudate (a); pallidum (b); putamen (c); or thalamus (d) as the seed region (p<0.001, uncorrected). Warm and cool colour shows positive and negative connectivity. BOLD contrasts are superimposed on a T1 structural image in axial sections from z=−20 to z=64, in neurological orientation. The adjacent sections are 12 mm apart. The colour bar represents voxel T value.
