As a noninvasive neuromodulation method, transcranial magnetic stimulation (TMS) shows great potential to treat a range of mental and psychiatric diseases, including major depression. Stimulating the deep brain helps researchers explore the causes of and possible treatments for psychiatric diseases, but current methods don't go quite deep enough and are largely restricted to superficial targets within the brain. In AIP Advances, from AIP Publishing, a group of researchers in China from Chengdu University of Technology and Huazhong University of Science and Technology present a new TMS array with a special geometrical-shaped magnet structure to help stimulate deeper tissue within the...
