All subjects underwent an MRI on a 3T Siemens scanner TrioTim syngo, equipped with an eight-channel transmit-and-receive head coil, using a magnetization prepared rapid gradient echo (MPRAGE) sequence (160 sagittal slices; slice thickness = 1 mm; field of view = 256 mm2; matrix = 256 × 240; voxel size 1.0 × 1.0 × 1.0 mm3; repetition time = 2300 ms; echo time = 2.98 ms; inversion time = 900 ms; flip angle = 9°). RsfMRI data used a T2*-weighted echo-planar sequence including 240 volumes with 36 AC/PC-aligned axial slices in interleaved order (slice thickness = 3 mm with 0.6 mm gap; field of view = 230 × 230 mm; matrix = 92 × 92; TR = 2000 ms; TE = 27 ms; flip angle = 80°). During task-free resting state sequences, the subjects were asked to lie still and close their eyes without falling asleep.

A 3-Tesla whole-body Siemens scanner (TrioTim Syngo; Siemens, Erlangen, Germany) with a 12-channel birdcage head coil was used for functional image acquisition with an interleaved T2-weighted echo-planar imaging gradient echo sequence (repetition time = 3,000 ms, echo time = 30 ms, flip angle = 90°; slice thickness = 3.0 mm; in-plane resolution = 3.4 × 3.4 mm; field of view = 220 mm; matrix size = 64 × 64). The experiment was performed in an fMRI room on an 8-inch screen, and the stimuli were presented using DMDX software. For each participant, 174 functional volumes were acquired. Anatomical images were also acquired using a T1-weighted 3D gradient echo pulse sequence with magnetization-prepared rapid gradient echo (repetition time = 1,670 ms, echo time = 1.89 ms, flip angle = 9°, slice thickness = 1.0 mm, in-plane resolution = 1 × 1 mm, field of view = 250 mm, matrix size = 256 × 256). The method of MRI data acquisition process was cited from Kim et al. study16 (link).

A 3-T whole-body Siemens scanner (TrioTim Syngo; Siemens, Erlangen, Germany) with a 12-channel birdcage head coil was used for functional image acquisition with an interleaved T2*-weighted echo-planar imaging gradient echo sequence (repetition time = 3000 ms for picture stimulus, 2000 ms for sound and Stroop stimuli; echo time/flip angle = 30 ms/90°; slice thickness = 3.0 mm; in-plane resolution = 3.4 × 3.4 mm; field of view = 220 mm; matrix size = 64 × 64). The experiment was conducted in an fMRI room using an 8-in. screen; stimuli were presented by means of DMDX software. For each participant, the following numbers of functional volumes were acquired: 174 for picture runs, 185 for Stroop runs, and 159 for sound runs. After fMRI, an anatomical image was acquired using a high, T1-weighted, 3D gradient echo pulse sequenced with magnetization-prepared rapid gradient echo (repetition time/echo time/inversion time/flip angle = 1670 ms/1.89 ms/900 m/9°, slice thickness = 1.0 mm, in-plane resolution = 1 × 1 mm, field of view = 250 mm, matrix size = 256 × 256). The total duration of the experiment was approximately 40 min. Before MRI was performed, previous hypnotics or psychotropic medication were washed out for at least four half-lives of the drugs. The method of MRI data acquisition process is cited from Kim et al. study21 (link).

Whole-brain MRI was conducted on a Siemens 3.0 Tesla MR scanner (Magnetom Trio Tim Syngo, Munich, Germany). A 32-channel head coil was used for radio frequency transmission and reception. Foam padding was positioned around the sides and top of the head to minimize head movement within the coil. A high-resolution T1-weighted anatomical image was acquired with a magnetization-prepared rapid acquisition with gradient echo sequence: matrix = 256, field of view = 230 mm, voxel size = 0.9×0.9×0.9 mm, slices = 192 (sagittal plane, acquired right to left), slice thickness = 0.9 mm, repetition time = 1900 ms, echo time = 2.32 ms, inversion time = 900 ms, flip angle = 9°, and sequence duration = 4 : 26 min. The anatomical scan sequence began approximately 15 minutes after the completion of the experimental condition. The entire MRI scanning session concluded approximately 90 minutes from the end of the exercise and rest conditions.

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.
