NEW YORK (Reuters Health) - Electrical stimulation of regions deep in the brain has become fairly common in recent years for treating Parkinson's disease symptoms, but there may be a simpler and safer alternative.

The results of a study in baboons suggest that stimulation of the motor control area on the brain's surface works too.

Delivering electrical stimulation to deep brain regions has been shown to help some people with Parkinson's, but the skill required to implant the electrodes, as well as the risks of electrode misplacement, have limited the use of this procedure.

Parkinson's symptoms have been tied to abnormal electrical activity in neurons in the main area that controls movement -- the motor cortex -- which is in the outer layer of the brain, a French team notes in the medical journal Neuron.
