For resting-state scanning, 303 images were acquired with a T2*-weighted gradient echo-planar imaging sequence for 10 min, 6 s (TR/TE = 2000/14 ms, flip angle = 80°, FOV= 24 × 24 cm2, matrix = 64 × 64, slice thickness = 4 mm without gap, 35 slices). All participants were instructed to keep their eyes closed, relax, and avoid falling asleep during the resting-state scanning.
