Researcher remotely controls colleague through brain signals

Posted: August 28, 2013 |   Comments



(http://www.usatoday.com) In an experiment at the University of Washington, a person's involuntary motion was remotely triggered by a researcher through a signal sent by thought.

The experiment was performed on August 12, 2013, by Rajesh Rao and Andrea Stocco to demonstrate human-to-human brain signaling, following the rapid technological advancement of brain-computer interfaces, devices that read and translate brain signals. Using these devices, amputees and paralyzed patients have been able to exert control over robotic prostheses.

In the experiment, Rao wore an electrical brain signal reading cap while observing a cannon-firing video game. By imagining his finger flicking during the game, a signal was sent to Stocco, who sat on the other side of the campus and wore a cap designed to send magnetic stimulation signals to his brain. When the thought signal reached Stocco, it caused his finger to move similarly to an involuntary twitch.

"The Internet was a way to connect computers, and now it can be a way to connect brains," Stocco said, in a statement. "We want to take the knowledge of a brain and transmit it directly from brain to brain."

The researchers plan to publish their results in a scientific journal.
