Transcranial Magnetic Stimulation for Modulating Muscle Response in Humans

Source: Kuhn, Y. et al. Intracortical Inhibition Within the Primary Motor Cortex Can Be Modulated by Changing the Focus of Attention. J. Vis. Exp. (2017)This video demonstrates the use of transcranial magnetic stimulation (TMS) to modulate motor neuron activity and measure muscle responses via electromyography (EMG). It outlines the steps for locating the motor hotspot, determining stimulation thresholds, and assessing the effects of subthreshold TMS (subTMS) on cortical inhibition.
