University of Washington University of Washington researcher Rajesh Rao, left, plays a computer game with his mind. Across campus, researcher Andrea Stocco, right, wears a magnetic stimulation coil over the left motor cortex region of his brain. Stocco’s right index finger moved involuntarily to hit the "fire" button as part of the first human brain-to-brain interface demonstration.
University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface , with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher. Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco's finger to move on a keyboard. While researchers at Duke University have demonstrated brain-to-brain communication between two rats, and Harvard researchers have demonstrated it between a human and a rat, Rao and Stocco believe this is the first demonstration of human-to-human brain interfacing. "The Internet was a way to connect computers, and now it can be a way to connect brains,” Stocco said. "We want to take the knowledge of a brain and transmit it directly from brain to brain. The researchers captured the full demonstration on video recorded in both labs. The following version has been edited for length.
