Whole brain resting state fMRI was performed on a 3-T Siemens Trio scanner with a 12-channel radio frequency coil. In the scanner, tape was placed across the participants’ forehead to serve as feedback for movement reduction. T2*-weighted functional images were acquired using a gradient-echo echo-planer imaging (EPI) sequence: TE = 29 ms, TR = 2 s, flip angle = 75°, slice thickness = 3.5 mm, slice gap = 1.05 mm, field of view = 240 mm, 64 × 64 matrix, voxel size = 3.75 mm × 3.75 mm × 3.5 mm. Resting-state scans were 5 minutes in duration. Subjects were instructed to keep their eyes open and fixate on a cross. High-resolution T1-weighted structural image were acquired with a 5-echo multi-echo MPRAGE sequence: TE = 1.64, 3.5, 5.36, 7.22, and 9.08 ms, TR = 2.53 s, TI = 1.2 s, flip angle = 7°, excitations = 1, slice thickness = 1 mm, field of view = 256 mm, resolution = 256 × 256 ×176, voxel size 1 × 1 × 1 mm, pixel bandwidth =650 Hz.
