Scientist controls colleague's hand in first human brain-to-brain interface
University of Washington researcher Rajesh Rao sends a brain signal to Andrea Stocco via the Internet, causing Stocco's right hand to move on a keyboard.
...brings new meaning to "hands free".
"...he imagined moving his right hand (being careful not to actually move his hand), causing a cursor to hit the "fire" button. Almost instantaneously, Stocco, who wore noise-canceling earbuds and wasn't looking at a computer screen, involuntarily moved his right index finger to push the space bar on the keyboard in front of him, as if firing the cannon."
