MRI scans were acquired using a 3.0 Tesla scanner (Trio whole‐body imaging system, Siemens Medical Systems, Iselin, NJ). A T1‐weighted magnetization‐prepared rapid gradient echo sequence was used (repetition time [TR] = 2300 ms, echo time [TE] = 2.13 ms, field of view = 256 mm, matrix size = 256 × 256; voxel size = 1.0 × 1.0 × 1.0 mm3, and flip angle = 9°) for volumetric analysis. For fMRI analysis, 155 volumes of echo planar imaging were acquired (TR = 2000 ms, TE = 30 ms, flip angle = 90°, number of slices = 75, matrix = 80 × 80, resolution = 2.0 × 2.0 × 2.0 mm3, 75 transverse slices, no slice gap, 5 min 20 s). All participants were instructed to relax, think of nothing, and keep their eyes closed but remain awake during scanning. No sedative drugs were given, and all participants reported that they did not fall asleep during the scanning.
Trio whole body imaging system
Manufactured by Siemens
Sourced in United States, Germany
The Trio whole-body imaging system is a medical imaging device designed for use in diagnostic and research applications. The core function of the Trio is to capture high-quality images of the human body using advanced imaging technologies. The system is capable of producing detailed visualizations of various anatomical structures and physiological processes, which can aid healthcare professionals in the diagnosis and monitoring of medical 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.
