Brain functional connectivity
By comparing the brain functional connectivity constructed for the cortical regions of interest, it was found that at α frequency, the regions of interest (ROI) were BA4, BA6, BA7, BA40, BA31, and BA24. The brain functional connectivity was significantly different at the local frontal, limbic, and frontal–parietal connections (Fig. Topography of functional connectivity differences between the two groups after treatment.
