Participant scanning occurred on a Siemens Tim Trio 3.0 Tesla MRI scanner (Siemens Medical Solutions, Erlangen, Germany) at the Advanced Imaging Research Center at OHSU. Task stimuli were presented from a laptop computer through a data projector to a screen at the rear of the MRI bore. Participants viewed stimuli through a mirror mounted on a 12-channel head coil and made responses with their right hands using a four-button opto-isolated button box.

A Siemens 3.0-Tesla Trio Tim MRI scanner (Siemens AG, Erlangen, Germany) equipped with a 12-channel phase-array head coil was used to acquire three-dimensional high-resolution structural images. The subjects were placed in the supine position and were asked to keep their head as still as possible during image acquisition. Before the scanning of structural images, T1-weighted, T2-weighted and fluid-attenuated inversion recovery (FLAIR) MRI sequences were implemented for each subject to exclude organic diseases and white matter hyperintensities. The following magnetization-prepared rapid gradient echo (MPRAGE) acquisition parameters were used: repetition time (TR) = 1900 ms; echo time (TE) = 2.52 ms; inversion time (TI) = 1100 ms; flip angle = 9°; field of view (FOV) = 256 mm × 256 mm; slice thickness = 1 mm; number of slices = 176; and voxel size = 1 mm × 1 mm × 1 mm.

A Siemens 3.0-Tesla Trio Tim MRI scanner (Siemens AG, Erlangen, Germany) was used to acquire structural images with a standard head coil. The subject was placed in a supine position during image acquisition. The head was fixed with sponge pads to reduce movement, and the subject was asked to keep the head as still as possible during the scan. The following magnetization-prepared rapid gradient echo acquisition parameters were used: repetition time (TR) = 1900 ms; echo time (TE) = 2.52 ms; inversion time (TI) = 1100 ms; flip angle = 9°; field of view (FOV) = 256 × 256 mm; slice thickness = 1 mm; number of slices = 176; and voxel size = 1 × 1 × 1 mm.

Participants were instructed to remain still, keep their eyes open, and focus on a fixation cross. MRI data were acquired using a Siemens Trio Tim 3.0 Tesla MRI scanner (Erlangen, Germany) and 32-channel head-coil. Sagittal T1-weighted anatomical images were acquired ∼10 min after each intervention using a magnetization prepared rapid gradient echo (MPRAGE) imaging sequence (TR = 1900 ms, TE = 2.3 ms, TI = 900 ms, flip angle = 9°, slice thickness = 0.9 mm, in-plane resolution = 0.9 × 0.9 mm, matrix = 300 × 320, field-of-view = 230 × 256 mm, duration = 4 min 26 s). Echo planar imaging (EPI) volumes were acquired ∼10 min after the completion of the MPRAGE scan (interim scans included field mapping and arterial spin labeling) using a multi-band sequence (TR/TE = 2000/24 ms, flip angle = 70, slice thickness = 3.0 mm, 36 slices, in-plane resolution = 3.0 × 3.0 mm, matrix = 64 × 64, volumes = 240, duration = 8 min 06 s). EPI images were acquired in the oblique axial plane (i.e., 20 relative to the anterior commissure–posterior commissure line) to reduce potential susceptibility artifact.

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.
