All neuroimaging procedures were conducted at the Center for Magnetic Resonance Research at the University of Minnesota on a Siemens Trio 3 Tesla MRI scanner (Erlangen, Germany). A T1-weighted scan was collected with the following parameters: TR = 2530 ms, TE = 3.65 ms, TI = 1100 ms, flip angle = 7 degrees, voxel size 1×1×1 mm³, GRAPPA = 2 (5 min). A dual spin echo, single shot, diffusion weighted echo planar scan was collected with the following parameters: TR = 8600 ms, TE = 90 ms, FOV 256 mm, voxel size 2×2×2mm³, 64 slices, GRAPPA = 2, 30 non-collinear volumes with b value = 1000s/mm² and 6 volumes with b = 0 s/mm²(5.5 min). The Siemens field map sequence was used which includes voxel parameters matching those of the DWI acquisition. This was collected for the purpose of correcting the DWI data for the geometric distortion caused by magnetic field inhomogeneities (2 min).

FMRI images were collected on a Siemens Trio 3-Tesla MRI scanner. Functional T2*-weighted echoplanar image volumes (EPIs; slice thickness = 3 mm, gap = 1 mm, 36 slices, TR = 2000 ms, TE = 25ms, flip angle = 90°, matrix = 64x64, FOV = 200mm) were acquired during each reliving scan.

Functional imaging was performed on a Siemens Trio 3 Tesla MRI scanner with an Echo Planar Imaging (EPI) sequences (repetition time, 2410 ms; echo time, 25 ms; flip angle, 80°; field of view, 192 × 192 mm²; voxel size, 3 × 3 × 2 mm³, 1 mm gap; 480 volumes) comprising 42 slices acquired in descending order and rotated approximately −25° to the bicommissural plane. For coregistration and normalization during pre-processing, a three-dimensional magnetization-prepared rapid gradient echo image was acquired (repetition time, 1900 ms; echo time, 2.52 ms; flip angle, 9°; field of view, 256 × 256 mm²; 192 sagittal slices; voxel size, 1 × 1 × 1 mm³). A field map was recorded to account for individual homogeneity differences of the magnetic field.
The PIT task was programmed using Matlab with the Psychophysics Toolbox Version 3 (PTB-3) extension [45 (link)]. Responses during PIT were made using a current-design MRI-compatible response box with the right index finger.

Functional MRI Acquisition Protocol

Participants were scanned (at baseline) in a Siemens Trio 3‐Tesla MRI scanner with 32‐channel head coil. Functional data were acquired with a 2D gradient‐echo planar sequence: 48 transverse slices, slice thickness = 2.5 mm, gap between slices = 0.5 mm, repetition time TR = 3.36 sec, TE 30 msec, and inplane resolution 3.0 × 3.0 × 3.0 m. The first five volumes were discarded to allow T1 equilibration.
A B0 field map was obtained after functional data acquisition: short TE = 10 msec; long TE = 12.46 msec; polarity of phase‐encode blips = −1; total EPI readout time = 37 msec, ascending slice order. Heart rate and respiration were monitored using an MRI‐compatible pulse oximeter (Nonin 8600 FO) and pneumatic belt,15 and recorded, along with scanner pulses via a Cambridge Electronic Devices Micro 1401 Mk11 connected to a laptop running Spike2 version 6. A T1‐weighted structural scan was acquired for each participant and used for normalization of functional data (TR = 7.92 msec, TE = 2.45 msec, T1 = 910 msec, flip angle α = 16°, 176 = slices, 1 × 1 × 1 mm voxels, FIV = 256 × 240 mm²16).

MRI scans from one 36 year old male right-handed subject with no history of neurologic or psychiatric disease were analyzed in this study. Scans were acquired as part of an MRI technology development protocol at the University of Pennsylvania. Informed consent was obtained in accordance with the University of Pennsylvania Institutional Review Board (IRB).

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.
