Functional MRI Task-Derived Intrinsic Connectivity

Functional MRI data were acquired on a single 3T GE Signa Twinspeed HDxT MR Scanner (GE Healthcare) using an 8-channel phased-array head coil. All participants completed 5 fMRI tasks, of which task-derived intrinsic connectivity data were estimated using a previously validated method.^{21 (link),22 (link)} The details of the acquisition, preprocessing, method for task-derived intrinsic connectivity, and handling of motion has been described previously^{23 (link)} and in the eMethods in Supplement 1.

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.
