(a) [11C]raclopride baseline scan. Right ventral striatal (R VST) DA D2 binding potential (BPND) positively correlates with area under the curve (AUC) in choice behavior for $20 across delays in all subjects with scans (n = 21; pFWE < 0.05 corrected for R VST anatomical volume). The boundaries of the striatal mask are shown in green. The color bar indicates the voxel-wise t statistic; display threshold at p < 0.01, uncorrected. (b) The nature of the correlation is illustrated by mean BPND extracted values (threshold p < 0.01), indicating that increased binding potential corresponds with increased preference for delayed monetary rewards.
