  1. The anatomical locations, approximate Brodmann areas (BA) and MNI coordinates that corresponded to the t-values of the representative peaks within each cluster were reported. A negative t-value means that fALFF was lower in this brain region when the AIS value is higher. All regions reached a voxel-level significance threshold of P < 0.001, FWE correct P = 0.05, cluster size> 30
