In the ventral DMN, the gray matter density of right parahippocampal gyrus was negatively linked to the FC of right superior frontal gyrus and middle frontal gyrus—right parahippocampal gyrus (r = −0.60, P < 0.01) and the right angular gyrus and middle occipital gyrus—right parahippocampal gyrus (r = −0.39, p = 0.0596) (Figure 3).
