Data acquisition
BLOOD
MRI scanning was performed using a 3 T Siemens Magnetom Vida MR scanner. Blood Oxygen Level-Dependent (BOLD) fMRI images were acquired using a gradient echo-planar-imaging (EPI) sequence [time of repletion (TR) = 1200 ms, time of echo (TE) = 30 ms, flip angle = 72°, slices/volume = 56, slice thickness = 2.5 mm, multiband acceleration factor = 3]. The anatomical, T1-weighted, images were collected with an ultrafast spoiled gradient echo pulse sequence (T1-TFE; TR = 1.60 ms, TE = 2.38 ms, flip angle = 9°, slices = 224, slice thickness = 1 mm). DWI data were collected using the same 3 T scanner with TR = 2800 ms, TE = 95 ms, flip angle = 90°, slices = 57, and slice thickness = 2.5 mm.
