SCZ, schizophrenia; OCD, obsessive-compulsive disorder; HC: healthy control; mPFC, medical prefrontal cortex; PCC, posterior cingulate cortex; BA, Broadmann area; x, y, z, coordinates of peak locations in the Montreal Neurological Institute space (MNI). Significance threshold was set at p < 0.05, FDR cluster level corrected, starting from voxel level p < 0.005 uncorrected.
