Transcranial magnetic stimulation (TMS) is a noninvasive method to cause depolarization or hyper-polarization of the neurons in the brain. TMS uses electromagnetic induction to induce weak electric currents using a rapidly changing magnetic field; this can cause activity in specific or general parts of the brain, allowing for the study of brain function and interconnectivity.
Single pulse TMS causes neurons in the neocortex under the site of stimulation to depolarize and discharge an action potential. If used in the primary motor cortex, it produces muscle activity referred to as a motor evoked potential (MEP) which can be recorded on electromyography. If used on the occipital cortex, ‘phosphenes’ (flashes of light) might be perceived by the subject. In most other areas of the cortex, the participant does not consciously experience any effect, but behaviour may be slightly altered (e.g., slower reaction time on a cognitive task), or changes in brain activity may be detected using sensory equipment.
TMS can be used to measure the activity and function of specific brain circuits in humans.
