Cluster p values (p < 0.05) with family-wise error correction across the whole brain. Map threshold p < 0.005, extent threshold ≥ 10 voxels;
↵*p < 0.05 with small volume correction correction (6-mm radius for striatum and midbrain; 10 mm for OFC) using coordinates from Neurosynth meta-analysis database (see Materials and Methods).
