By Mayo Clinic staff

Transcranial magnetic stimulation is an experimental procedure that uses magnetic fields to stimulate nerve cells in the brain in the hope of improving chronic depression symptoms. Transcranial magnetic stimulation is one of the newer types of brain stimulation methods designed to treat depression when standard treatment hasn't worked.

There are different ways to perform transcranial magnetic stimulation. But in general, a large electromagnetic coil is placed against your scalp near your forehead. The electromagnet creates painless electric currents that stimulate nerve cells in the region of your brain involved in mood regulation and depression.
