Resting-state fMRI Acquisition Protocol

MRI scanning was performed on a 3.0 T Siemens Tim Trio MRI (Erlangen, Germany). The resting-state fMRI images were acquired using a gradient-echo-planer imaging (EPI) sequence, the scan parameters were as follows: TR = 2000 ms, TE = 35 ms, flip angle FA = 68°, slice thickness = 3 mm (no slice gap), matrix size = 64 × 64, FOV = 208 × 208 mm², time point = 220, and acquisition time = 7.26 min, resulting in a voxel size of 3.3 × 3.3 × 3.0 mm^{3 (link)}. Subjects were instructed to close their eyes, remain still, and relax, without falling asleep during scanning.

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.
