A "data cable" made from stretched nerve cells could someday help connect computers to the human nervous system. The modified cells should form better connections with human tissue than the metal electrodes currently used for purposes such as remotely controlling prosthetics. . . Connecting the chord to electrodes outside of the brain means the reaction of neurons to non-organic material can be controlled. In future, the cord could connect an amputee's nerves to a sophisticated prosthetic, he says, and might even offer a way to connect artificial eyes or ears to the brain.
Bring it on. I've said it before and I'll say it again: I'll be the first in line to get a brain implant.
