Because of a chip implanted on the brain to capture the impulses the brain sends to the body, doctors and researchers may have already found a way to make machines work just with these impulses.

A brain chip developed by John Donoghue form Brown University was used in the clinical trials done by Cyberberkinetic's BrainGate Neural Interface System. In this tests, researchers were able to capture signals sent by the brain to different body parts. Before, there was no way to interpret what these signals actually meant, but with this chip, signals from the brain could now be interpreted. These signals in turn were "read out" via mathematical techniques.

Amazingly enough, these interpreted signals were converted into simple commands that could be used to turn lights on and off, control computers and control television sets. Donoghue, the brain chip creator, is also hoping that someday soon these interpreted signals sent by the brain could be used to control artificial limbs, like a robotic arm.
