Magnetic resonance imaging (MRI) structural images were acquired on a Philips Achieva 3.0 T scanner using a SENSE-8 head coil. Head movements were minimized by applying a band over the forehead during the scanning procedure. A high-resolution T1-weighted MRI volume data set of the whole brain with a resolution of 1 × 1 × 1 mm³ was acquired using an MPRAGE (Magnetization Prepared Rapid Gradient Echo) sequence: Repetition time (TR) = 8.2 ms, echo time (TE) = 3.8 ms, flip angle = 8°, sense factor: 3.5.

Resting state imaging data were collected using a Philips Achieva 3.0T scanner with a 32-channel headcoil and a gradient-echo echo-planar imaging sequence with the following acquisition parameters: TR=3000msec; TE=30msec; 46 3mm thick axial slices aligned to the AC-PC line, 0.30mm slice gap; 216 × 216mm FOV, (2.70mm³ voxels); flip angle = 90°. Four initial volumes were acquired and discarded by the scanner computer to allow for T1 equilibration effects. After that, 124 volumes were acquired. During both scanning sessions a high resolution T1-weighted image (MPRAGE sequence) was acquired for co-registration and normalization to the MNI coordinate system. Subject head motion was minimized with foam packing around the head.
Images were processed using SPM 12 (Wellcome Trust Centre for Neuroimaging). Standard preprocessing of functional images included slice-time correction, spatial realignment to correct for head motion, coregistration to the participant’s T1 image and warping to MNI space, resampling to 2mm³, and smoothing with an 8mm FWHM isotropic Gaussian kernel. Volumes were identified as motion outliers based on image intensity difference (dvars) or framewise displacement (fd; >0.5mm) using FSL’s motion outlier tool (Power et al. 2012 (link)).

Imaging was done on a Philips Achieva 3.0T scanner using a 32-channel headcoil and a gradient-echo echo-planar imaging sequence with the following acquisition parameters: TR=2000; TE=28; 39 3mm thick axial slices aligned to the AC-PC line, 0.6mm slice gap; 19.2×19.2cm FOV; SENSE factor = 2, Flip angle = 77°. Four images were acquired and discarded just prior to task start. A high resolution T1-weighted image (MPRAGE sequence) was also acquired to assess for incidental findings, and for alignment and spatial standardization of the functional data. Subject head motion was minimized with foam packing around the head. Stimuli were viewed via projection onto a mirror mounted on the headcoil.

Magnetic resonance imaging (MRI) was performed with a Philips Achieva 3.0 T scanner and a 32-channel receive head coil (Philips, Best, The Netherlands). During the precision grip task, whole-brain fMRI scans were acquired with an Echo Planar Imaging (EPI) sequence with repetition time (TR) = 2500 ms, echo time (TE) = 30 ms, and flip-angle of 80˚. Each brain volume consisted of 42 axial slices acquired in interleaved order with a slice thickness of 3 mm, resulting in a 3x3x3 mm voxel resolution and a field-of-view (FOV) of 192x192x126 mm. For quantifying lesion load and overall brain atrophy, structural MRI including T1- and T2-weighted and Fluid Attenuated Inversion Recovery (FLAIR) images were obtained. The T1-weighted image was acquired with a sagittal magnetization prepared rapid acquisition gradient echo (MPRAGE) sequence (TR = 6 ms, TE = 2.70 ms, flip-angle = 8°, 0.85 mm isotropic voxel size and a FOV of 245x245x208 mm). The T2-weighted image was acquired with a turbo spin echo sequence (TR = 2500 ms, TE = 270 ms, flip-angle = 90°, 0.85 mm isotropic voxel size and a FOV of 245x245x190 mm). The FLAIR image was acquired with a TR = 4800 ms, TE = 327 ms and an isotropic voxel size of 1 mm³ resulting in a FOV of 256 × 256 × 202 mm.

A Philips Achieva 3.0T scanner with a standard head coil was used to acquire gradient-echo EPI images of the whole brain (TR, 1.0 s; TE, 30 ms; 21 slices; slice thickness = 6 mm; spacing = 0; field of view = 210 mm; flip angle = 76°; image matrix: 64 × 64; voxel size: 3.28 × 3.28 × 6.00 mm³; number of fMRI frames: 360). During the 6-minute resting-state fMRI scan, subjects were instructed to relax, stay awake, and have their eyes closed; postscan self-report questionnaires indicated that subjects did comply with these instructions. Time-locked cardiac and respiratory signals were recorded. High-resolution anatomical images were acquired at the end of the experiment. There was no other task in the scanner prior to resting-state data acquisition.

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.
