Brain regions showing an increase in functional connectivity with the medial OFC in the moral condition relative to the unpleasant condition. For this analysis, the mean signal time courses of the right medial OFC cluster (center coordinate,x = 17, y = 42,z = −7) were obtained from each subject (from the same cluster coordinates). Linear regression detected any voxel in the brain that increased its coupling with the signal of the right OFC. The statistical threshold was set at p < 0.002 (uncorrected), adjacent voxels in the cluster withp < 0.005 (t > 2.8), and a minimum cluster volume of 50 mm³. There was a marked increase in coupling of the right medial OFC with the MedFG, superior temporal sulcus, and precuneus.
