Answer:Transcranial Magnetic Stimulation (TMS)
Explanation:
Transcranial magnetic stimulation also known as repetitive transcranial magnetic stimulation. TMS is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. In TMS, brain cells are stimulated using a powerful magnetic field produced by a wire coil placed on a person's head that temporarily inactivates neural circuits. TMS devices operate completely outside of the body and affect central nervous system activity by applying powerful magnetic fields to specific areas of the brain that we know are involved in depression.
