Data were collected using a 3T Siemens Trio MRI scanner. For each task run, functional T2*-weighted echoplanar images (EPIs) were collected with the following parameters: slice thickness = 4 mm, 34 slices, TR = 2 s, TE = 30 ms, flip angle = 90°, matrix 64 x 64, FOV = 192 mm, oblique slice orientation. Additionally, a T2-weighted matched-bandwidth high-resolution anatomical scan (same slice prescription as EPI) and MPRAGE were collected. The parameters for the high-resolution scan were: 4mm slices, TR/TE=5000/34, 4 averages, matrix = 128x128, 90 degree flip angle. The parameters for MPRAGE were the following: TR = 1.9 s, TE = 2.26 ms, FOV = 250, matrix = 256 x 256, saggital plane, slice thickness = 1 mm, 176 slices. DTI parameters were: 64 directions, 2mm slices, TR/TE=9000/93, 1 average, 96x96 matrix, 90 degree flip angle, axial slices, b=1000
The number of EPIs collected for each task are as follows:
