Included in tables 2 and 3 are those of the 20 ROIs that were assessed (10 in each hemisphere) where the noted effect attained volume-corrected probability <.05 at the peak voxel, and for comparative purposes, the homologous ROI in the opposite hemisphere. The size and spatial-extent probability associated with the largest cluster, the total proportion of the ROI constituted by all clusters, and the peak voxel Z-score, associated probability, and MNI coordinates are tabled. ACCsg = supragenual anterior cingulate cortex, ACCig = infragenual anterior cingulate cortex
Statistical significance maintained after applying the Bonferroni correction for 40 comparisons (.05 / 40 = .0012).
