The PMNE group showed significantly decreased ALFF values in the Frontal_Med_Orb_L, compared to the control group. The data are expressed as the mean ± SD, and the error bars represent the SD. *P < 0.001. Frontal_Med_Orb_L: left medial orbital superior frontal gyrus; ALFF: amplitude of low frequency fluctuation; NC: normal control group; Patient: PMNE group.
