VULCAN MIND MELD’: FIRST HUMAN BRAIN-TO-BRAIN COMMUNICATION LETS SCIENTIST CONTROL ANOTHER PERSON’S MOVEMENT

                                                 Remember  Star Trek II: The Wrath of Khan 
                                                                 



Researchers have made the first step in human telepathy, creating a brain-to-brain interface that allows one person to control the motions of another.
Mind control technology has been making strikes in the medical field, helping paralyzed or disabled patients feed themselves and fly drones as researchers hope to give them more independence. But these instances have only been using a person’s brain activity to power a device, like a robot.
In contrast, researchers at the University of Washington used the brain signals of one person to control the hand motions of another person.

The brain signals were sent over the Internet, allowing Rajesh Rao to move Andrea Stocco’s finger on a keyboard, according to the university’s website.
“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.”

The brain-to-brain interface involves one participant wearing a cap with electrodes that are attached to an electroencephalography machine. This cap picks up the brain’s electrical signals and transfers the information to the other person, who in this experiment was sitting on the other side of the university’s campus, wearing a cap with a transcranial magnetic stimulation coil above his left motor cortex, an area of the brain that controls hand movement.
Here’s more about how the experiment was conducted:
Rao looked at a computer screen and played a simple video game with his mind. When he was supposed to fire a cannon at a target, he imagined moving his right hand (being careful not to actually move his hand), causing a cursor to hit the “fire” button. Almost instantaneously, Stocco, who wore noise-canceling earbuds and wasn’t looking at a computer screen, involuntarily moved his right index finger to push the space bar on the keyboard in front of him, as if firing the cannon. Stocco compared the feeling of his hand moving involuntarily to that of a nervous tic.
