Remote Brain-to-brain messagings and actionsOne brain sends instructions to another grain hundreds of meters away and moves the second person's finger in a deliberate way
"U.S. scientists are reporting a non-invasive, human-to-human brain interface allowing one researcher to control the hand movements of a fellow researcher.
Using electrical brain recordings and a form of magnetic stimulation, University of Washington researcher Rajesh Rao sent a brain signal to fellow scientist Andrea Stocco on the other side of the university campus, causing Stocco's finger to move on a keyboard.
Rao and Stocco said they 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."
Essentially, person A (Rao) consciously thought about moving his finger in a way that would have it press a key and fire a cannon in the on-screen video game in front of him, but was careful not to
make any movements of his hand or finger. The neural signal was transmitted through the air between his research helmet and an electrode-wired headgear on person B (Stocco) elsewhere on the campus, and B's finger twitched and moved to the very same key on his keyboard as the one A was thinking of pressing, although B had no idea of what action would be attempted, what key the other one might press, or indeed what finger he would choose. In fact, B didn't have a screen to look at.
This is amazing and, like the head transplantation scheme, is bound to set one's thoughts going in all directions. If you can do this with two brains, separated by a fairly wide space, it would surely be possible in the future to exchange either part for a computer. So a pc, a smartphone or a robot could be used to make one person - or a thousand - perform a movement. Or a series of movements. Or create or suggest memories in those people. Or even bleep out memories? Zombies, anyone? Or literally getting inside someone else's mind?
Of course the researchers stress this is very bare-bones and doesn't offer any chances, at this point, of doing anything advanced or forcing anyone's hand if they don't want the action, but well...That's true about this early stage, what about the future though?
