The gray matter volume of right hippocampus was negatively associated with the FC between (1) right hippocampus—right angular cortex (r= −0.55, P < 0.05); and (2) right hippocampus—left hippocampus (r = −0.45, P < 0.05) in the dorsal default network. The left hippocampus size was negatively linked to the FC between the left hippocampus—right angular cortex (r = −0.42, P < 0.05) (Table 4; Figure 2).
