What is transcranial magnetic stimulation?</h3>
Transcranial magnetic stimulation is a minimally invasive method of stimulating the brain that uses electromagnetic induction to induce an electric current in a particular region of the brain.
An electromagnetic pulse is painlessly delivered by the electromagnet, stimulating nerve cells in the part of the brain responsible for mood regulation and depression. It is believed to stimulate brain areas that are less active while depressed.
TMS is a method of treatment for a major depressive disorder that has received FDA approval (MDD). The prefrontal cortex region of the brain, which is underactive in depressed individuals, is stimulated using a machine that uses focused magnetic pulses.
