Imaging was acquired across three scanning sites (University of Chicago, University of California, Los Angeles, and Massachusetts General Hospital/Harvard Medical School) using a unified acquisition protocol. Structural scans were acquired on a 2 Siemens Magnetom Prismafit 3T scanners (UCLA and MGH/Harvard) and one Philips Achieva 3T MRI scanner with dStream (Chicago) all with 32-channel head coils, using a MPRAGE acquisition sequence with the following parameters: slab orientation = sagittal, FOV 256x256x176, voxel size 1x1x1 mm3, inversion delay time TI = 900 ms, TR = 2310 ms, TE = 2.9 ms flip angle = 9 degree. Functional task MRI was acquired with a single-shot gradient echo planar imaging sequence. Thirty-nine interleaved axial slices parallel to the AC–PC line covering the whole brain were acquired: TR = 2000 m s, TE = 28 ms, flip angle = 90°, field of view = 210 × 210 mm, matrix = 205 × 205, voxels size 3.2x3.2x3.1mm and a 20% distance factor, GRAPPA acceleration factor = 2 (for the 2 Siemens scanners) and SENSE acceleration factor 2 (for the Philips scanner).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
