Scanning parameters
BLOOD, BEST
Scanning was performed on a 3‐Tesla Philips Achieva MRI scanner (Philips Medical Systems, Best, The Netherlands). Before the functional scans, a high‐resolution anatomical T1‐weighted scan with the following parameters was obtained for co‐registration and normalization purposes: 3.8 ms echo time, 8.4 ms repetition time, 288 × 288 × 175 mm field of view, 175 sagittal slices, flip angle of 8.0°, voxel size of 1.0 mm isotropic.Blood oxygen level‐dependent (BOLD) response was measured with functional T2*‐weighted axial whole‐brain images. In each session, 490 volumes were acquired during the task using a 2D‐EPI‐SENSE sequence with 51 slices, a flip angle of 65°, voxel size of 2.5 mm isotropic, a SENSE factor of
