Sensory loss has a profound effect on millions of people’severyday lives. Sight, hearing, touch, smell, and taste can allbe affected, diminishing their experience of the world. Butnow, thanks to neuroprosthetic technology we can tap intonerve and brain function, and rewire these lost connections.Neuroprosthetic devices, or implants, restore sensory functionaffected by injury or disease. Cochlear implants use electrodesto stimulate the auditory nerve sodeafpeople can hear, oftenfor the first time. Artificialretinasrestore sight, prosthetichands and electronic skin can simulate touch, and implants fortaste and smell are being developed.Still, the most well-recognized neuroprosthetics are cochlearimplants. NASA engineer Adam Kissiahdevelopedthe blueprintfor modern devices in the 1970s. An implant digitizes soundreceived from an external microphone, using a speechprocessor for spoken sound, and feeds it via radio frequencyto an electrode array embedded in the cochlea of the innerear.
