The imaging data were acquired on a General Electric (GE) Discovery MR750 3 Tesla scanner (General Electric Medical Systems, Milwaukee, USA) in a 32-channel receive-only phased-array head coil in the Mind Research Imaging center at the National Cheng Kung University. High-resolution structural images were acquired with a fast-spoiled gradient recalled pulse sequence consisting of 166 axial slices (TR/TE/flip angle 7.6 ms/3.3 ms/12°; a field of view (FOV) 22.4 × 22.4 cm2; matrices 224 × 224; slice thickness 1 mm). Each functional scanning runs 8 alternating cycles of task and fixation blocks with an additional fixation block at the beginning. The EPI images were collected using an interleaved T2* weighted gradient-echo planar imaging (EPI) pulse sequence (TR: 2,500 ms, TE: 30 ms, Flip angle:77°, matrix size: 64/64, FOV: 22 cm/1x, slice thickness: 4 mm, voxel size, 3.4375 × 3.4375 × 4 mm, number of slices:32). A total of 208 volumes and 6 dummy scans were acquired for each condition. The visual stimulus was displayed using PsychoPy v2020.1.3 on an MSI GS65 Stealth laptop and was projected onto a screen that was viewed through a mirror attached to the head coil.

Structural and functional magnetic resonance images were acquired using a General Electric (GE) Discovery MR750 3 Tesla MRI scanner. A 3D MPRAGE sequence obtained high-resolution anatomical images (FOV = 240 mm x 192 mm, slices/volume (axial) = 186, slice thickness = 0.9 mm, image matrix = 256×256, voxel volume = 0.938×0.938 × 0.9 mm, TR/TE = 5/2.012 ms, acceleration factor R = 2, flip angle = 8°, inversion/delay time TI/TD = 725/1400 ms, scan time = 340377 ms) using an 8-channel receive-only head coil (GE). Functional data were collected as echo-planar image (EPI) volumes depicting BOLD contrast (180 EPI volumes per run, slice thickness = 2.9 mm, voxel volume = 1.875×1.875 × 2.9 mm, acquisition matrix = 96×96, TR = 2000 ms, TE = 27 ms, flip angle = 78°, axial-oblique slices, 39 slices per volume, scan time = 360 s) using an eight-channel head array coil (GE), with a sensitivity encoding (SENSE) factor of 2 to minimize EPI distortions while also increasing the number of slices collected per TR.
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.
