For example, in a "bionic" arm, neural impulses are transmitted to electrodes that then trigger muscle movements in the shoulder or upper arm; electrodes placed on those muscles capture the brain's impulses and relay those commands via wires to motors that operate the elbow, wrist and fingers. Similarly, neural implant technology is used to help the deaf and blind. View the entire article online at NationalGeographic.com.
