Clusters showing significant group differences in functional connectivity with the posterior cingulate cortex (PCC)

		MNI coordinates
Region	Voxel size	x	y	z	BA	t(56)
R cingulate cortex	214	8	2	44	24	4.72
R superior parietal lobule/postcentral gyrus	207	12	−48	70	7	4.11
L postcentral gyrus	185	−42	−20	32	2	4.72
L postcentral gyrus/superior parietal lobule	152	−14	−44	60	7	4.20
R anterior insula/central operculum	150	44	−4	2	13	4.42
L insula/putamen	115	−34	−12	4	–	4.71

All reported clusters are significant at P_{FDR-corrected} <0.05, two-sided, based on whole-brain correction. There were no clusters in which patients showed significantly greater functional connectivity than controls. Montreal Neurological Institute (MNI) coordinates and t-statistics are given for peak voxel location.
