 Transcranial magnetic stimulation TMS is a minimally invasive brain stimulation technology that can focally stimulate the brain of an awake individual.1,2 A localized pulsed magnetic field transmitted through a figure-8 coil lasting only microseconds is able to focally stimulate the cortex by depolarizing superficial neurons3,4 which induces electrical currents in the brain.5 If TMS pulses are delivered repetitively and rhythmically, the process is called repetitive TMS rTMS.
