All participants provided written informed consent before scanning. Resting-state fMRI scans were collected at seven sites using a 3T Siemens Tim Trio System scanner in six locations and a 3T General Electric Discovery MR750 scanner in one location. Participants were asked to lay still, stay awake and keep their eyes closed during the whole scan duration. In all sites, T2∗-weighted gradient-echo echo-planar images (EPIs) were acquired with the following parameters: voxel size = 3.4375 × 3.4375 × 4.0 mm3, repetition time (TR) = 2 s, eco time (TE) = 30 ms, flip angle (FA) = 77 degrees, field of view (FOV) = 220 × 220 mm (64 × 64 matrix), slice thickness = 4 mm, gap = 1 mm, number of slices = 32 sequential ascending slices. Scans lasted 5:4 min, a total of 162 volumes of echo planar imaging BOLD fMRI were collected.

Imaging data were acquired using two different types of scanner. Data from six sites were collected on a 3T Siemens Tim Trio System scanner and 3T General Electric Discovery MR750 scanner was used for one site. A standard gradient-echo echo planar imaging (EPI) paradigm consisting field of view (FOV)220 × 220 mm (64 × 64 matrices), repeat time (TR) = 2 s, echo time (TE) = 30 ms, flip angle (FA) = 77  , 162 volumes, 32 sequential ascending axial slices of 4 mm thickness and 1 mm skip was used to obtain restingstate fMRI scans.

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.
