Transcranial magnetic stimulation (TMS) is a noninvasive method to cause depolarization in the neurons of the brain. TMS uses electromagnetic induction to induce weak electric currents using a rapidly changing magnetic field; this can cause activity in specific or general parts of the brain with minimal discomfort, allowing the functioning and interconnections of the brain to be studied. A variant of TMS, repetitive transcranial magnetic stimulation (rTMS), has been tested as a treatment tool for various neurological and psychiatric disorders including migraines, strokes, Parkinson's disease, dystonia, tinnitus, depression and auditory hallucinations...

Study on the Effect of External Magnetic Stimulation on Patients With Parkinson's Disease
The purpose of this research study is to test the usefulness of external magnetic stimulation (EMS) for treating the motor, cognitive, and neuropsychiatric symptoms of Parkinson's disease (PD).

Participants with Parkinson's disease will be recruited at the PADRECC of the Philadelphia VA Medical Center. Enrolled participants will be randomly assigned to receive either active external magnetic stimulation or fake stimulation. The external magnetic stimulation is delivered by wearing a helmet that is embedded with many small circuits which produce a very small magnetic field around the head. The helmet is to be worn daily for two minutes immediately before bedtime for three months in a row. The helmet is for investigational use only and has not been approved for use by the FDA.

ScienceDaily (Jan. 29, 2011)

...Transcranial magnetic stimulation (TMS) is a relatively new method of pain-free stimulation of cerebral nerve cells. The method, which was presented by Anthony Barker for the first time in 1985, is based on the fact that the cortex, the rind of the brain located directly underneath the skull bone, can be stimulated by means of a magnetic field... "In general, the activity of the cells drops as a result of a low-frequency stimulation, i.e. with one magnetic pulse per second. At higher frequencies from five to 50 pulses per second, the activity of the cells increases. This rhythm is based on the natural theta rhythm of four to seven Hertz which can be observed in an EEG,"...
