Transcranial Magnetic Stimulation
Rapid transcranial magnetic stimulation; Repetitive transcranial magnetic stimulation
Transcranial magnetic stimulation (TMS) is a noninvasive technique for stimulating cells of the cerebral cortex and inducing an electrical current through a magnetic coil that produces neuronal depolarization and generation of an evoked response in a peripheral muscle.
TMS was originally used to map cortical motor control and hemispheric dominance and also has applicability as an alternative method of clinical treatment. Initially introduced by Merton and Morton in 1980, the transcranial electrical stimulation (TES) produced a brief, high-voltage electric shock over the primary motor cortex (M1) followed by a brief, relatively synchronous muscle response, the motor evoked potential (MEP). TES was thought to be useful for different purposes but also found to be painful. In 1985, Barker et al. improved the technique and demonstrated it was possible to stimulate the...
