Significant differences between the HC and MDD groups emerged for within-DMN connectivity (Fig. 1A). The MDD group had stronger lagged phase synchronization between a region in the right superior frontal gyrus (SFG; corresponds to region ‘R DMN-A’ in Table 1) and a region in the right parahippocampal gyrus (PHG; region ‘R DMN-E’ in Table 1), in the beta-2 frequency band (18.5–21 Hz; p<0.05, FWE-corrected). Contrary to our hypotheses, there were no group differences in within-FPN connectivity when examined at p<0.05 FWE-corrected or p<0.001 (uncorrected).
