MRI data were acquired on a 3.0 T TRIO Prisma MRI (Siemens, Erlangen, Germany) wholebody MRI system equipped with a 64-channel head matrix coil. Each participant was fitted with cushions in the head coil to help stabilize the head position. Participants viewed the monitor via an adjustable mirror positioned on top of the head coil. Functional images were obtained using a blood oxygenation level-dependent (BOLD) contrast sensitive gradient-echo echo-planar sequence. A total of 1355 images were acquired in each experimental session and, respectively, 244 images in each positional localizer run; scanning parameters: TR = 1200 ms, TE = 30 ms, flip angle = 70 degree, FOV = 192×192 mm, voxels size = 2 × 2 × 3 mm, slices number = 36, slice thickness = 3 mm.
Structural MRI images (T1-weighted) were acquired from the sagittal plane a using three-dimensional magnetization-prepared rapid gradient-echo (MP-RAGE) pulse sequence; scanning parameters: TR = 1780 ms, TE = 2.51 ms, flip angle = 8 degree, FOV = 256 × 256 mm, voxel size = 0.9 × 0.9 × 0.9 mm, slice thickness = 0.9 mm.
