 Depressed patients show prefrontal hypoactivity and abnormally increased activity in the limbic regions. High-frequency rTMS increases regional cerebral blood flow in the left DLPFC with clinical improvement. However, the effects of rTMS on intrinsic functional connectivity between the left DLPFC and limbic regions are still not clear. We sought to examine changes in resting EEG functional connectivity before and after high-frequency left prefrontal rTMS in patients with treatment-resistant depression. We found that left prefrontal rTMS modulates more synchronized middle beta band activity between the left DLPFC and limbic regions. This suggests that rTMS might be related to GABAergic circuits modulation.
