PACG<HSs	Left middle frontal gyrus	10	−4.8234	39	−42	42	15
PACG<HSs	Right superior frontal gyrus	9	−3.9157	27	6	57	27
PACG<HSs	Right precuneus	23	−4.8576	30	9	−54	30
PACG<HSs	Left precentral gyrus	9	−4.9299	34	−45	12	33
PACG<HSs	Right angular gyrus	39	−4.3023	51	45	−66	33
PACG<HSs	Left superior frontal gyrus	9	−4.3136	43	−18	24	39
PACG>HSs	Right precentral gyrus	6	4.418	26	26	−12	69

Notes: The statistical threshold was set at voxel with P<0.005, cluster size with P<0.05 and cluster size ≥26 between PACG and HSs, corrected by AlphaSim.
