1.   That was made possible in part by recent advances in implanted electrode recording techniques.

2.   The processor transmits digital simulations of sound through a surgically implanted electrode, called a cochlear implant, to stimulate nerve endings in the inner ear.

3.   The device, also known as a cochlear implant, uses surgically implanted electrodes, which transform sound vibrations into nerve impulses that are relayed to the brain.

4.   They may allow more sophisticated control over leg nerves and muscles, although there has been some problems with long-term maintenance of the implanted electrodes, she said.
