RTMS for Treatment of Pain and Craving

Transcranial magnetic stimulation (TMS) is a minimally invasive brain stimulation technology that can focally stimulate the brain of an awake individual. A localized pulsed magnetic field transmitted through a figure-8 coil (lasting only microseconds) is able to focally stimulate the cortex by depolarizing superficial neurons, which induces electrical currents in the brain. TMS pulses that are delivered repetitively and rhythmically are referred to as repetitive TMS (rTMS). In this study TMS is being delivered with the MagVenture MagPro B60 coil.

The MagVenture MagPro system has an integrated active sham that passes current through two surface electrodes placed on the skin beneath the B60 coil.
