Significant correlations between the MMSE scores and the connection strength of the PMC subregions in the patient groups. The correlations between the MMSE scores and the changed connection strength of the PMC subregions were calculated and false discovery rate (FDR) was used for multi-comparison correction with p < 0.05. (A) Left PMC subregions (B) Right PMC subregions. MCI patients are indicated by blue circles, mAD patients by green rhombuses, and sAD patients by red triangles. L, left; R, right; SFG, superior frontal gyrus; MFG, middle frontal gyrus; MPFC, medial prefrontal cortex.
