A subject who was paralyzed below his shoulders in a bicycling accident, is believed to be the first person with quadriplegia in the world to have arm and hand movements restored with the help of two temporarily implanted technologies. A brain-computer interface with recording electrodes under his skull, and a functional electrical stimulation (FES) system activating his arm and hand, reconnect his brain to paralyzed muscles.
A cochlear implant is an electronic device capable of restoring hearing in a profoundly deaf person by stimulating the nerve endings in the inner ear. However, results can be extremely variable. Using brain imaging techniques, a neuroscientist and a surgeon have managed to predict the success of a cochlear implant among people who became profoundly deaf in their adult life.
