All MRI experiments were carried out on a 3T Siemens Prisma MRI scanner (Prisma, Siemens, Germany) with a 64-channel head/neck coil. Prior to imaging acquisition, participants were instructed to lie still, to let their mind wander, and to keep eyes closed once the scanning started. MRI-safe soft ear plugs were put into their ears to provide hearing protection. And the gap between their head and the coil was filled with foam paddings to minimize head movements.
The three-dimensional T1-weighted images (3D-T1WI) were acquired using a magnetization prepared rapid acquisition gradient echo (MPRAGE) sequence with the following parameters: Sagittal, 176 slices, slice thickness (ST) = 1 mm, repetition time (TR) = 2,300 ms, echo time (TE) = 2.98 ms, inversion time (TI) = 900 ms, data matrix = 248 × 256, field of view (FOV) = 248 × 256 mm2, and flip angle (FA) = 9°.
DTI images were obtained using a single-shot echo-planar imaging (EPI) sequence, whose parameters were configured as 70 continuous axial-oblique (parallel to the anterior-posterior commissural line) slices, 64 acquisitions with diffusion weighting (b = 1,000 s/mm2, 1 acquisition for each of 64 non-collinear diffusion sensitization gradients) together with three acquisitions without diffusion weighting (b = 0 s/mm2), ST = 2 mm, TR = 4,200 ms, TE = 68 ms, data matrix = 132 × 132, and FOV = 264 mm × 264 mm.
Resting-state fMRI data were collected using a gradient echo EPI sequence under an eye-closed condition. The online configuration of scanning parameters was specified as 75 continuous axial-oblique (parallel to the anterior-posterior commissural line) slices, ST = 2 mm, TR = 2,000 ms, TE = 30 ms, data matrix = 94 × 94, FOV = 220 mm × 220 mm, FA = 60°, and 240 volumes in total.
