MRI scans were performed at National Yang-Ming University in Taiwan using a 3 T Siemens MAGNETOM Tim Trio MRI Scanner (Siemens Healthcare, Erlangen, Germany) with a 12-channel head coil. Participants were instructed to relax with their eyes closed, without falling asleep. High-resolution structural T1-weighted (T1w) images were acquired with three-dimensional magnetization prepared rapid gradient-echo sequence (3D-MPRAGE; repetition time, TR = 2,530 ms, echo time, TE = 3.5 ms, TI = 1,100 ms, field of view, FoV = 256 mm, flip angle = 7°, 192 sagittal slices, voxel size = 1.0 mm3, no gap). Resting-state functional MRI was acquired using a gradient echo-planar imaging (EPI) sequence (TR = 2,500 ms, TE = 27 ms, FoV = 220 mm, flip angle = 77°, matrix size = 64 × 64 × 43, voxel size = 3.44 mm × 3.44 mm × 3.40 mm). The rs-fMRI scan consisted of 200 contiguous EPI volume, which was acquired along the anterior commissure–posterior commissure plane. Total scan time for T1w and rs-fMRI was 17 min for each participant (Localizer: <1 min, T1w: 8 min, Resting: 8 min).

MEG data were recorded at a 600 Hz sampling rate using a 151-channel whole-head MEG system with axial gradiometers (CTF/MISL, Coquitlam, B.C.) at the Hospital for Sick Children in Toronto. Data were recorded continuously with an on-line bandpass of 0–100 Hz, and filtered off-line to 0.1–30 Hz. Fiducial coils were placed at the nasion and pre-auricular points to localize the subject's head relative to the MEG sensors at the start and finish of the experiment. Participants lay supine in the MEG dewar while completing the task inside a dimly lit magnetically shielded room. Head localizations (with an accuracy of 1 mm) were completed before and after the experimental procedure. Head movements were continuously monitored throughout the recording procedure using a video camera. The MEG study required 15–20 min. Following the MEG recordings, for structure-function co-registration purposes, fiducial coils were replaced with MRI contrast markers in the same locations and an anatomic MRI was acquired on a 3 T MAGNETOM Tim Trio MRI scanner (Siemens AG, Erlangen, Germany). A high-resolution T1-weighted volumetric MRI image was acquired for each participant using a 3D MPRAGE sequence.

Data were acquired on a 3 T Magnetom TIM Trio MRI scanner (Siemens, Erlangen, Germany) at the Max Planck Institute for Metabolism Research, Cologne. As the task was partially self-paced, a slightly different number of volumes was acquired for each subject (mean = 1217, approximately 40.5 min experiment duration). T2*-weighted echo-planar images (EPI) sensitive to blood-oxygenation level-dependant (BOLD) contrast were acquired during the task (TR = 2 s; TE = 30 ms; flip angle = 90°; 30 axial slices; in-plane resolution = 3.3 × 3.3 mm; slice thickness = 2.7 mm; slice gap = 1.35 mm). Magnetic equilibration was accounted for via scanner automatic dummy removal. Images were acquired in parallel to the anterior-posterior commissural plane. Cardiac and breathing rates were recorded peripherally during scanning. Anatomical T1-weighted volumes were also acquired for each subject (TR = 1.9 s; TE = 3.51 ms; flip angle = 9°; field-of-view 256 × 256 × 128; voxel size 1.0 × 1.0 × 1.0 mm).
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.
