^∗ P < 0.05; ^∗∗P < 0.01; NS, not significant. T < 0 represented the functional connectivity in ApoEε4 carriers was lower than the noncarriers. T > 0 represented the functional connectivity in ApoEε4 carriers was higher than the noncarriers.

PCC, posterior cingulate cortex; lLP, left lateral parietal; rLP, right lateral parietal; liTmp, left inferior temporal; rpCBLM, right posterior cerebellum; mdThal, medial thalamus.
