Scientists are developing various ways to bypass damaged parts of the brain in order for patients to regain normal functioning. These ways are known as neuroprosthetics or electronic devices that replace damage parts of the brain and sensory organs. The most famous neuroprosthetic is the cochlear implant which allows hearing impaired individuals to hear. Researchers are now in the process of creating systems like this to "turn off" chronic pain, return movement to paralyzed patients, as well as to restore memory and curb the sensation of hunger. This only adds to the existing cochlear and retinal implants.
