750 mri scanner

Below we outline the imaging parameters for the three separate imaging experiments included in the current manuscript. All scans were performed on a 3.0T GE 750MRI scanner using a 32-channel head coil.

Participants were scanned on either a 3.0T GE Sigma MRI scanner (Scanner 1) or a 3.0T GE 750 MRI scanner (Scanner 2) in the Clinical Research Center on the National Institutes of Health campus (Bethesda, MD, USA) as part of independent experiments.
Across scanners, partial volumes of the occipital and temporal cortices were acquired.
Scanner 1: eight-channel head coil; 28 slices; 3 mm³ voxel size with 10% interslice gap; TR = 2. TE = 30 ms; matrix size = 64 × 64, FOV = 192 mm.
Scanner 2: thirty-two channel head coil; 37 slices; 3 mm³ voxel size with 10% interslice gap; TR = 2. TE = 30 ms; matrix size = 64 × 64, FOV = 192 mm.

During fMRI scanning, the participants lay in a supine position in the MRI tunnel while looking at the stimulus on the screen in the mirror, which was fitted to the head coil (viewing angle, 5 × 2.5°). Scanning was performed at Kangning Hospital in Shenzhen, using a 3T GE 750 MRI scanner with an 8-channel head coil. A gradient–echo planar imaging (EPI) sequence was used [TR (repetition time)/TE (echo time) = 2000/30 ms; flip angle = 90°; voxel size of 3 × 3 × 3.5, with a 0-mm gap]. After functional scanning, an anatomical image was acquired using a T1-weighted spin echo pulse sequence with a 1-mm³ isotropic voxel size.
