Table 1. Regions showing significant changes in VMHC between depression patients before and after ECT.

Brain regions	BA	Voxel number	t-score	MNI coordinates (x, y, z)
Superior frontal gyri	8	42	5.6490	±9, 42, 45
Middle frontal gyri	8/9	35	6.0747	±48, 15, 45
	10	33	7.2623	±42, 51, -3
Angular gyri	39	97	6.1551	±48, −66, 27

Abbreviations: BA, Brodmann area; ECT, electroconvulsive therapy; VHMC, voxel-mirrored homotopic connectivity; MNI coordinates, Montreal Neurological Institute coordinates of the peak voxel; t, statistical value of the peak voxel; 1 voxel=3 × 3 × 3 mm³. VMHC computation bases on a symmetrical template, so the MNI coordinates of the peak voxel is also symmetrical.
