FC calculation
Seed reference time series of each ROI was extracted separately by averaging the time series of all voxels within the ROI. Next, Pearson’s correlation analyses were performed between the seed reference time course of each ROI and time series of the entire brain in a voxel-wise manner. To improve normality, the resultant correlation coefficients were transformed into z-values by using Fisher’s z-transformation.For FC analysis, two-sample
