The seed regions were defined by generating a 6-mm radius in ROIs based on ReHo-TR correlation results. The time series of each voxel in each ROI were averaged first. FC was then calculated as the correlation coefficients between the averaged time course of these ROIs. A Fisher’s r-to-z transform was then performed to convert the correlation coefficients to z values in order to improve the normality of these correlation coefficients.
