Pictorial representation of TMS. (A) Transcranial magnetic stimulation involves placement of a magnet coil over the scalp to induce an electric field. This electric field passes through the scalp and skull to act directly on the targeted brain area. (B) When applied to the primary motor cortex, an electrical impulse travels down the corticospinal tract and results in a targeted muscle contraction. (C,D) A relaxed muscle will contract with targeted TMS. Source: Biorender.com.
