Within-group Functional Connectivity Maps of the HC (left) & svMCI (right) Groups

Widely spread regions of parietal, frontal, occipital and temporal lobes exhibited high functional connectivity values in the both groups. 

Note that the posterior cingulate (PCC) and adjacent precuneus (PCu) showed the highest functional connectivity density in the both groups. The statistical threshold was set at P<0.001 for individual voxels and cluster size >324 mm3, which corresponded to a corrected P<0.01 determined by Monte Carlo simulations.
