Preprocessing of resting-state fMRI data
Data were preprocessed by the Data Processing Assistant for Resting-State fMRI (DPARSF) version 4.0. (For ReHo and DC, the time series of resting-state fMRI data of each voxel was linearly detrended and temporally bandpass filtered (0.01−0.08 Hz). The mean framewise displacement (FD) was calculated by averaging the FD of each subject across the time points. Each subject’s mean FD was included in all group-level analyses as a covariate to further control the head movement effect.
