Transcranial magnetic stimulation

A procedure used to treat patients with depression.

transcranial magnetic stimulation,

n a diagnostic tool comparable to a nerve conduction study; uses a surface magnetic impulse over a client's head, and electrical stimulation over the neck, thus resulting in stimulation of the upper motor neurons and nerve tract so that the timing of electrical impulse from the brain to the muscle can be measured. Has also been used to treat neurologic conditions, such as migraine, epilepsy, insomnia, depression, and alcoholism.
