Brain imaging data were acquired on a Signa Excite 1.5 T MR imaging system (General Electric, Fairfield, USA) and a standard head coil. Foam pads were used to reduce head motion and scanner noise. All participants were asked to hold still, with eyes open and instructions to stay awake. The eyes open resting-state fMRIs were acquired by using an echo planar imaging sequence with the following parameters: 26 axial slices, thickness/skip = 4/0 mm, in-plane resolution =64 × 64, repetition time (TR) = 2000 ms, echo time (TE) = 30 ms, flip angle = 90, field of view = 240 mm × 240 mm, 190 volumes. Axial T1-weighted images (T1WI), were also obtained with a T1 FLAIR sequence with TR = 2307 ms, TE = 10.6 ms, and TI = 620 ms.

Structural and functional brain imaging data were acquired on a Signa Excite 1.5T MR imaging system (General Electric, Fairfield, USA) and a standard head coil. Foam pads were used to reduce head motion and scanner noise. All participants are required to remain still, open their eyes, and listen to instructions to complete the language task. The language task fMRI data were acquired by using an echo planar imaging (EPI) sequence with the following parameters: Repetition time (TR) = 2000ms, echo time (TE) = 30ms, flip angle = 90, 26 axial slices, thickness/skip = 4/0mm, in-plane resolution = 64 × 64, 190 volumes.
Structural images include axial T2WI (TR = 2300ms, TE = 108ms, FoV read = 230mm, 17 axial slices, voxel size = 0.6×0.6×6.0mm3), axial FLAIR (TR = 9000ms, TE = 134ms, FOV read = 230mm, 17 axial slices, voxel size = 0.7×0.7×6.0mm3) and T1 3D-MPRAGE (TR = 2300ms, TE = 2.26ms, FOV read = 256mm, 176 sagittal slices, voxel size = 1.0×1.0×1.0mm3).

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.
