Cochlear Implants
French surgeon André Djourno and engineer Charles Eyries made an important observation during their experiments on electrical stimulation. They noticed that by directly stimulating the auditory nerves with electrical signals, they could elicit auditory sensations. This observation laid the foundation for the development of cochlear implants, which are devices designed to bypass damaged parts of the ear and provide direct stimulation to the auditory nerves, enabling individuals to regain their hearing capabilities. With advancements in technology and surgical techniques, cochlear implants have continued to improve, offering recipients better sound quality and enhanced speech comprehension.
