The MRI data were collected from a 3.0-Tesla SIEMENS Magnetom Trio Tim scanner in Xijing Hospital. Resting-state fMRI images were acquired with an echo planar imaging (EPI) sequence using the following parameters: repetition time (TR) = 2,000 ms, echo time (TE) = 30 ms, flip angle (FA) = 90°, matrix = 64 × 64, slice thickness = 4 mm, slice number = 33, and field of view (Fov) = 220 mm × 220 mm. The subjects were told to lie still in the scanner, eyes closed, but not to fall asleep. We collected 240 fMRI scans for each subject.
