Brain MRI and resting-state fMRI acquisition and preprocessing
BRAIN
Brain images were acquired with a 3.0-T GE Discovery 750 MRI scanner (GE Healthcare, Chicago, IL). Participants were asked to keep their eyes open without thinking or moving during the scan. A standard head coil (eight channels) with foam padding was used to restrict head motion. All imaging was acquired along the anterior–posterior commissural plane, as identified by multiplanar T1-weighted BRAVO anatomical images (repetition time, 12.2 ms; echo time, 5.2 ms; flip angle, 12°; voxel size, 1 × 1 × 1 mmBriefly, the fMRI data were preprocessed with Statistical Parametric Mapping (SPM12;
