Sending electric signals into the brain could eliminate Parkinson's symptoms

Symptoms of Parkinson's disease in mice disappeared when their brains were stimulated via spinal electrodesA ground-breaking medical device that eliminates the symptoms of Parkinson's disease by electrically stimulating the brain could be tested in humans as early as next year, according to scientists working on the project.The device has produced dramatic improvements in mice with a Parkinson's-like disease, raising hopes that it could transform the lives of the four million people worldwide who have the devastating condition.In tests, mice that suffered constant tremors and were barely able to walk because of the disease started moving around, groomed themselves and began eating and drinking normally when the device was switched on."If we see the same effect in people as we see in rodents, then Parkinson's patients will be able to walk and move around the way they could before the disease came on.
