Whole-head, high-resolution T1-weighted structural images were collected using one of two custom 32-channel head coils made for children112 (link), a 12-channel coil, or the standard Siemens 32-channel head coil in 176 interleaved sagittal slices (TR = 2,530 ms, TE= 1.64/3.5 ms/5.36 ms/7.22 ms, resolution = 1 mm isotropic). Whole-brain functional BOLD data were collected in 32 near-axial slices (3 mm thick) in an interleaved order with a 20% distance factor (TR = 2,000 ms, TE = 30 ms, flip angle = 90°, bandwidth = 2298 Hz/Px, custom pediatric coils: FoV = 192 mm; standard 32-channel head coil: FOV = 256 mm; 12-channel head coil: FOV = unavailable, phase encoding A>P direction, matrix size = 64x64, in-plane resolution = 3 mm × 3 mm). PACE was used to adjust the position of the gradients based on the participant’s motion one TR back111 (link).

Whole-brain MRI was performed using a 3 T Verio scanner equipped with a 32-channel head-coil (Siemens, Erlangen, Germany). Whole-brain MRI was performed using a 3 T Verio scanner equipped with a 32-channel head-coil (Siemens, Erlangen, Germany). Image pre-processing was performed with statistical parametric mapping (SPM) software (version: SPM8 revision 4667; Wellcome Department for Neuroimaging, University College London). Structural T1-weighted images were acquired using a Magnetization Prepared Rapid Acquisition Gradient Echo (MPRAGE) sequence (TR 1900 ms, TE 2.32 ms, flip angle 9°). The field of view (FOV) covered the whole brain (FOV 230 × 230 × 230 mm) with a slice thickness of 0.9 mm. The T1 images were segmented into grey and white matter and cerebrospinal fluid compartments.

Imaging data were gathered at the Department of Radiology, Yeouido St. Mary’s Hospital, The Catholic University of Korea, using a 3T Siemens Skyra scanner and a 32-channel Siemens head coil (Siemens Medical Solutions, Erlangen, Germany). The T1-weighted volumetric magnetization-prepared rapid gradient echo scan sequences used the following parameters: TE = 2.6 ms, TR = 1940 ms, inversion time = 979 ms, FOV = 230 mm, matrix = 256 × 256, and voxel size = 1.0 × 1.0 × 1.0 mm3. A multiband gradient-echo EPI acquisition method was adopted for resting-state functional image acquisition, with TE = 86.0 ms, TR = 3100 ms, slice acceleration factor = 3, slice thickness = 2 mm, FOV = 224 mm, matrix = 128 × 128 × 29, and voxel size = 1 × 1 × 2 mm3. A total of 150 volumes were collected over a period of 5 min while the participant was instructed to “keep your eyes closed and think of nothing in particular”.

MRI measurements were performed with a 3 Tesla TIM-TRIO system (Siemens Healthcare, Erlangen, Germany) using a 32 channel Siemens head coil. Functional images were acquired using a 2D single shot echo planar imaging sequence (repetition time = 2500 ms, echo time = 28 ms, flip angle = 90°, in-plane acceleration = GRAPPA 2) with 34 axial slices covering the whole brain (field of view = 230 mm, voxel size = 1.8 × 1.8 × 3.0 mm, no gap). Each of the 10 functional runs consisted of 56 volumes and lasted 140 s. A T1-weighted structural image was acquired using a magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequence (repetition time = 2300 ms, echo time = 3.36 ms, inversion time = 900 ms, flip angle = 9°, voxel size = 0.9 mm isotropic). To minimize head motion artefacts, individually constructed plaster cast helmets were used (Edward et al., 2000 ).

All task MRI data and all in-lab resting-state MRI data were acquired using a 32-channel Siemens head coil in a horizontal bore 3 Tesla Siemens Tim Trio located at the Harvard University Center for Brain Science in Cambridge, MA. Gradient echo EPI sequences were used for all tasks (TR = 2600 ms, TE = 30 ms, Flip angle = 90°, voxel size = 3.0 × 3.0 × 3.1 mm, 42 slices, whole brain coverage). Magnetization Prepared Rapid Gradient Echo (MP-RaGE) T1-weighted high-resolution data (TR = 6.6 ms, TE = 2.9 ms, Flip angle = 8°, voxel size = 1.0 × 1.0 × 1.3 mm) were acquired for each participant on the same scanner as the task data. In-lab resting-state data consisted of two runs of 6 min each (278 timepoints). The Human Connectome Project (HCP) resting-state data consisted of four runs of fifteen minutes of resting state data per subject. The runs were normalized across time and concatenated to give us sixty minutes of resting state data per subject.

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.
