Overall memory performance correlations with right hippocampal intrinsic connectivity (A); and right PPC intrinsic connectivity (B). The PPC, left lateral parietal region, and medial prefrontal region, where intrinsic connectivity with the right hippocampal seed predicts the overall memory performance on the post-scan recognition task in these older adults, were showed in (A). Notably, these regions are also the nodes constituting the default network. The right hippocampus, and a region in the left superior frontal gyrus, where intrinsic connectivity with the right PPC seed predicts the overall memory performance on the post-scan recognition task in these older adults, were showed in (B). The maps were thresholded at p < 0.005 (uncorrected) with an extent threshold of 10 contiguous voxels.
