How Transcranial magnetic stimulation works?
TMS works on principals of electrical current established in the last few centuries. In 1831, Faraday discovered that a rapidly changing magnetic field can induce electrical current in a nearby conductor. In 1985 this principle was used to induce twitches in humans’ arm and leg muscles. The magnetic fields used in TMS are produced by passing current through a hand-held coil, whose shape determines the properties and size of the field. The coil is driven by a machine which switches the large current necessary in a very precise and controlled way, at rates up to 50 cycles per second in rTMS (Repetitive transcranial magnetic stimulation). The coil is held on the scalp – no actual contact is necessary – and the magnetic field passes through the skull and into the brain. Small induced currents can then make brain areas below the coil more or less active, depending on the settings used. A related registration and tracking application is the generation of functional brain mapping using a tran
