What is deep brain stimulation?
Brain stimulation is the term used to describe the use of electrical stimulation to stimulate the brain.
It is widely used in many countries to treat various conditions, including Parkinson’s disease, but it is also used to treat epilepsy and brain trauma.
It involves stimulating areas of the brain that are vital for controlling impulses, including the cerebellum, a part of the cerebral cortex that controls movement and balance.
