Brain Implants and its Future
Today, brain implants are fraught with risks just like how laser eye surgery was a few years back. Though the target is miniscule of the patient population, the novel technology is set to unravel medical marvels that were once a part of science fiction. Neuroprosthetics are different from implanted insulin pumps or dental crowns or pacemakers. It is a device that helps in restoring or supplementing the capacities of the mind by inserting electronics into the nervous system. This device assists a human mind to change its way of perceiving the world and function through it and becomes a part of the human character. Neuroprosthetics, in fact, is a device that has been commercially used for almost three decades as cochlear implants for people with hearing problems across the world.
The external device, which can either be a camera or a microphone captures both sounds and images and then processes those sounds or images results of which it uses to drive electrodes. These electrodes further stimulate the optic or the audible nerves, which becomes the naturally formed output transferred from ear to eye. Today, thousands of Parkinson’s patients use another kind of common implant that helps in activating few motor controlled pathways by sending electrical pulses to deep inside a brain. After inserting a small electrode into the brain through a little hole in the skull it is connected with a wire that runs to pack of battery fixed under the skin. This helps in reducing or eliminating the tremors and other particular syndromes that Parkinson’s patients generally suffer from. With a hope to have more advanced technologies to help Parkinson’s patient live easy life ahead and more definite use cases, brain implants might witness innovation in the long run.
