The Human Brain : From Neurone to Nervous System

CLINICAL NEUROPHYSIOLOGY : Transcranial Magnetic Stimulation (TMS)

  1. Transcranial magnetic stimulation (TMS) is a procedure that uses magnetic fields to stimulate nerve cells in the brain. An electromagnet is used to create pulses of electric current that stimulate nerve cells in the region of the brain beneath the magnet.

  2. When cortical neurones, such as those of the motor cortex, are excited, impuses in the corticospinal axons activate alpha motoneurones, and the characteristics of these responses can be used to examine the function of the motor pathway under investigation.
