Image acquisition
MRI of the brain was carried out using a Siemens 3T MAGNETOM Trio. A T1-weighted (MPRAGE) structural scan (voxel size: 1×1 × 1 mm) was collected and used for registration purposes. A T2*-weighted, gradient echo planar image (EPI) scan sequence (TR, 3000 ms; TE 30 ms; voxel size: 3×3×3 mm) was used to collect functional imaging data during the word cue task.
