Neuroprosthetics is a field of medical science that focuses on the development and use of artificial devices to replace or enhance the function of a person's nervous system. The devices rely on signals from the nervous system to provide sensory feedback and control, allowing people with neurological or physical impairments to regain control over their bodies. Neuroprosthetics can also be used to create new pathways in the nervous system, allowing people to bypass damaged areas and regain a level of independence and quality of life.
