Regions of increased DA were taken from the BPND, BL>BPND, SS contrast. Regions of decreased DA were taken from the BPND, SS>BPND, BL contrast. MNI, Montreal Neurological Institute; k, cluster size; SST, stop signal task; STG, superior temporal gyrus; IPL, inferior parietal lobe; SMG, supramarginal gyrus; SMA, supplementary motor area; ITG, inferior temporal gyrus; MFG, middle frontal gyrus; SFG, superior frontal gyrus; IFG, inferior frontal gyrus; OFC, orbitofrontal cortex; ACC, anterior cingulate cortex. Statistical threshold was P<.005, uncorrected, k>10 voxels.
