The structural MRIs of each young adult of the HCP release were acquired on a single 3T Siemens Skyra scanner with a 32-channel head coil and housed at Washington University in St Louis (Glasser et al. 2013). T1-weighted MRIs were acquired using the gradient-echo MPRAGE sequence (TR = 2400ms, TI = 1000ms, TE = 2.14ms, flip angle = 8°, matrix = 320×320, FOV = 22.4cm, slice dimensions = 0.7×0.7×0.7mm, 256 slices). T2-weighted MRIs were acquired using the spin-echo SPACE sequence (TR = 3200ms, TE = 565ms, variable flip angle, matrix = 320×320, FOV = 22.4cm, slice dimensions = 0.7×0.7×0.7mm, 256 slices, GRAPPA acceleration = 2).
