Control a computer with your brain? Ha, no problem.
The ability to control a computer using only the power of the mind is closer than one might think
Brain-computer interfaces, where computers can read and interpret signals directly from the brain, have already achieved clinical success in allowing quadriplegics(the paralysis of all four limbs or of the entire body below neck), those suffering “locked-in syndrome” or people who have had a stroke to move their own wheelchairs or even drink coffee from a cup by controlling the action of a robotic arm with their brain waves. In addition, direct brain implants have helped restore partial vision to people who have lost their sight.
