(CNN) - Researchers believe they've connected two human brains via the internet for the first time without any invasive procedures.
A professor at the University of Washington was able to send the signal to a research assistant's brain. The professor watched a video game screen and, using his brain, made his assistant hit the spacebar when it was time to fire a missile.
Those brain signals were sent to a device on the other side of the campus that magnetically stimulated the part of his assistant's brain that controls his right hand. That caused his hand to twitch, hitting the button.
Researchers explain the brain signals used in this case were pretty basic. They can't transfer thoughts and they were only transmitted one way.
The next step, they say, is trying to transmit more complex information from one brain to another.
