All imaging data were acquired using a Siemens 3 T Magnetom Trio Tim Syngo MR B17 scanner with a 12-channel head coil. T1-weighted images (T1) were obtained for each participant to enable spatial localization and normalization and were acquired using the three-dimensional (3D) magnetization-prepared rapid-acquisition gradient echo (MPRAGE) sequence in the sagittal plane with the following parameters: repetition time (TR) = 1670 ms, echo time (TE) = 1.89 ms, voxel size = 1mm3, field of view (FOV) = 250 mm, flip angle = 9° and 208 slices. Resting-state fMRI data were acquired using echo-planar imaging (EPI) in the axial plane with the following parameters: TR = 3500 ms, TE = 30 ms, FOV = 240 mm, flip angle = 90°, matrix = 128 × 128, voxel size = 1.9 × 1.9 × 3.5 mm3, 35 slices, and 116 timepoints. During the fMRI scan, which lasted for 6 min and 58 s, each subject was instructed to relax with his/her eyes closed but not to fall asleep.
To minimize possible head movements and subsequent motion artifacts, the subjects were asked to move as little as possible during image acquisition, and head cushions were also used. All images were visually inspected to exclude the presence of artifacts or gross anatomical abnormalities that could impact image processing.
