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 positive t-value means that fALFF was increased in this brain region after acupuncture treatment. All regions reached a voxel-level significance threshold of P < 0.001, FWE correct P = 0.05, cluster size> 30
