At the University of Washington in Seattle, they used one person's brain to control another person's brain & actions.
It's the first human-to-human brain interface.
Here's how it worked - researcher Rajesh Rao was hooked up to an electrode cap watching a computer screen, playing a video game with his mind.
Rao IMAGINED moving his hand to press a key.
That brain signal went across the internet and across campus to another researcher, Andrea Stocco, who was wearing an electrical brain stimulator.
Suddenly, Stocco's right index finger moved -
"Yay! yes!" hooted the researchers in both laboratories.
The researchers say it was both exciting and eerie to watch someone remotely control another person's brain.
They say what's depicted in sci-fi is far from reality yet, but they've proven the concept.
The Washington researchers say the possibilities for this new technology are endless.
