Abstract
Let’s imagine the cruise control of your car locked at 120 km/h on any road in any condition (city, country, highway, sunny or rainy weather), or your car air conditioner set on maximum cold in any temperature condition (even during a snowy winter): would you find it efficient? That would probably not be the most optimal strategy for a proper and comfortable driving experience. As surprising as this may seem, this is a pretty accurate illustration of howdeep brain stimulation is used today to treat Parkinson’s disease motor symptoms and other neurological disorders such as essential tremor, obsessive-compulsive disorder, or epilepsy.
