Whole-brain BOLD fMRI data were acquired on a 3.0 Tesla GE Signa system, Excite2 release, (Milwaukee, WI), standard radio frequency coil. Functional imaging was performed using T2*-weighted single-shot combined spiral in/out acquisition (Glover and Law, 2001): repetition time (TR)=2000 ms, echo time (TE)=30 ms, flip angle=90°, field-of-view (FOV)=0cm, 64×64 matrix, slice thickness=4mm, 29 slices. High-resolution anatomical T1 scans were acquired for spatial normalization. Motion was minimized with foam pads and emphasis on the importance of keeping still.
