Mechanism of action of TMS: To quantify the strength and confirm the activity of the TMS, MEPs are used. Once the TMS coil is fired, cortical neurons signal via the corticospinal tract to the stimulated targeted muscle activity. These MEPs can be quantified as excitatory or inhibitory depending on the muscle’s movement or lack thereof. Adapted from Klomjai et al. [24].
