We’re still a long ways off from achieving technologically-enabled telepathy, but a recent question-and-answer experiment by researchers at the University of Washington shows that progress is being made.
An upgraded brain-to-brain interface has allowed researchers to transmit signals from one person's brain over the internet and use those signals to control the hand motions of another person. Remarkably, the system allowed the participants to collaborate on a computer game.
You may never become Xavier from the X-Men, able to read and control people's minds. But one day, using a computer interface, you could control somebody else's behavior and possibly even communicate using thought. The technology you see demonstrated in this video is the first step.
We already have brain-computer interface systems that allow people to control cursors on a screen using the power of thought. But what about sharing thoughts between two minds? A group of neuroscientists at Harvard have found a way to do it — with a human and a rat.
