Brain To Brain Communication Now A Reality

An incredible new breakthrough is being perfected, as researcher have now confirmed brain to brain communication is possible.

Getting its start in 1998, Miguel Nicolelis, a Brazilian researcher working at Duke University, started experimenting with the brains of rats, measuring the electrical output of a single neuron at a time, and in recording the information, discovered that to make their bodies move.

Then moving up to the evolutionary ladder, trained monkeys to play a video game using a joystick, and found that after having recorded the brain patterns that resulted from the movement, the team took the joystick away and the monkey was now able to move the dot around simply by imagining it move.

“Somehow she figured out that she could just imagine. She realized this is the prototype of a free lunch. This was the first time a primate’s brain liberated itself from the body.

Now, Chantel Prat and Andrea Stocco, both researchers at the University of Washington Institute for Learning and Brain Sciences, wanted to see if they could send a message to control physical movement from one brain to another but because it’s a breach of research ethics to connect probes directly into a living human brain, they had to figure out how to do it using non-invasive techniques.

Using an electroencephalography (EEG) cap, which records brain activity, they positioned two researchers in separate areas of the campus. In one room a colleague, Rajesh Rao, played a videogame using his mind, while transmitting the thoughts to Stocco sat with his back to the same video game while wearing noise-canceling headphones so he wouldn’t know when to respond.

A transcranial magnetic stimulation coil (a device that can emit a focused electrical current) which was positioned directly over the part of the brain that controlled the movement of his finger so that when Rao thought about moving his finger, the signal was transmitted across campus to Stocco who would twitch his finger.

“The first time I didn’t even realize my hand had moved. I was just waiting for something to happen,” said Stocco.

Nicolelis assures us that this will not lead towards thought policing by stating “I don’t think we will ever be able to broadcast from one brain to another the essence of the human condition. We don’t even know how to record those things let alone broadcast them and then interpret that broadcast. We love analogies, metaphors, expecting things, and predicting things. These things are not in algorithms. We’re not going to be broadcasting my dreams to your head.”
