α < 0.001 uncorrected for whole brain analysis (WB) and α < 0.05, corrected for multiple comparisons (family-wise error – FWE) in ROI analyses with a minimum cluster size of k = 5. L = left, R = right hemisphere. ns = no significant activation. The cluster with the largest number of significant voxels within each region is reported. Coordinates x, y, and z of the peak voxels are given in Montreal Neurological Institute space.
