Scanning was performed on a 3T Siemens Trio scanner equipped with a 32-channel head coil. The protocol included a high-resolution sagittal T1-weighted 3D gradient-echo sequence (MPRAGE), 160 contiguous slices, 1 mm isotropic voxel, repetition time (TR) 2300 ms, echo time (TE) 2.98 ms, field of view 256 mm. We prevented head movements by cushioning the participant's head in the coil with padding.
