Note: Side refers to the hemisphere side (B: bilateral; R: right; and L: left). The Brodmann areas (BAs), the coordinates of peak t-value in Montreal Neurological Institute (MNI) space, the volume in voxels, and the peak t-value are specified for each region showing group differences in regional homogeneity (ReHo).
