Researchers Rajesh Rao and Andrea Stocco from the University of Washington have connected two human brains together for the first time, allowing one subject to control the other’s finger on a keyboard remotely, through the power of thought. The scientists had one subject wearing an electrode studded cap play a video game in one lab, whilst another, without a screen but with a keyboard, sat in the next room along. He was able to tap the keyboard and play the game without being able to see the screen, proving the theory.
