The correlation between the Z scores of the altered functional connections and the MMSE in the slow-4 and slow-5 bands. (A,B) The Z scores of the decreased functional connections, including L_AG - R_AG and R_AG -R_MGF, in AD group compared with NC group are positively correlated with the MMSE in the slow-5 band. (C,D) The Z scores of the increased functional connections, including L-IPL – PCUN and L_IPL-L_PCC, in AD group compared with NC group are negatively correlated with the MMSE in the slow-5 band. (E,F) The Z scores of the decreased functional connections, including R_AG-R_MFG and PCUN- R_MFG, in AD group compared with NC group are positively correlated with the MMSE in the slow-4 band.
