A Siemens Magnetom Trio 3T whole body MRI scanner and a thirty-two-channel head coil were used. Multi-band accelerated echo planar imaging sequencing (Center for Magnetic Resonance Research, Minnesota) was used with an acceleration factor of 6 and iPAT acceleration factor of 2. T2*-weighted EPI slices were obtained every 0.7 s (TR = 0.7, TE = 0.03), these parameters were optimised given our scanner capability and used to increase sampling rates and increase our power to detect resting state networks as has been shown previously with multiband (Xu et al., 2013 (link), Filippini et al., 2014 (link)). 54 transverse slices with in-plane resolution of 2.4 × 2.4 mm were attained and slice thickness was 2.4 mm. The matrix size was 96 × 96 and the field of view (FOV) were 230 × 230 mm. Acquisition was performed during resting-state scan, yielding 400 vol in total. Sagittal 3D MPRAGE images were also acquired with an isotropic in-plane resolution of 1 × 1 × 1 (TI = 0.9 s, TR = 2.02, flip angle 9°, FOV = 250 × 250 mm) yielding 192 slices.
Thirty two channel head coil
Manufactured by Siemens
Sourced in Germany
The thirty-two-channel head coil is a specialized piece of lab equipment used for magnetic resonance imaging (MRI) procedures. It is designed to be placed around the head of a patient or research subject to capture high-quality images of the brain and surrounding areas.

The experimental protocol consisted of an event-related interleaved design. A Siemens Magnetom Trio 3T whole body MRI scanner and a thirty-two-channel head coil were used. Multi-band accelerated pulse sequencing (Version number RO12 Center for Magnetic Resonance Research, University of Minnesota, EPI 2D BOLD/SE/DIFF Sequence) was used with an acceleration factor of 6. T2*-weighted echo planner imaging slices were obtained every 0.7 seconds (TR). Imaging parameters were chosen to reduce distortion artefact in the orbitofrontal cortex (Wilson et al., 2002) . 54 Axial slices with in-plane resolution of 2.4 x 2.4mm and between plane spacing of 2.4mm were attained. The matrix size was 96 x 96 and the field of view were 230 x 230mm. Acquisition was performed during task performance, yielding approximately 3500 volumes. An anatomical T1 volume with sagittal plane slice thickness 1mm and in-plane resolution of 1.0 × 1.0 mm was also acquired.
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.
