US scientists have opened the way for the development of a bionic eye. They used electrodes to stimulate an area of the brain that processes visual information, the Proceedings of the National Academy of Sciences reported. The results in monkeys increase the chance that people with conditions such as glaucoma will one day have their vision restored with a prosthetic eye. But experts warned it would be a big hurdle to implant enough electrodes to recreate an entire image in the mind. Researchers have looked at several ways of restoring sight to people who have become blind because of an accident or common diseases such as macular degeneration. In such patients, the eye has ceased to function but the visual centres in the brain are intact. The goal is to bypass the eye and stimulate the visual parts of the brain to recreate an image in the mind.Are you happy of this discover? will function? discuss
