Cybernetic Telepathy: Neuroscientists Successfully Create Brain-to-Brain Network

A revolutionary discovery has been made as researchers have successfully created the world’s first “brain-to-brain” network.

The ability to send thoughts from brain to brain is no longer just a fantasy limited to science fiction movies.

According to reports, a team of researchers at the University of Washington in Seattle (USA) has invented a revolutionary brain-to-brain communication system.

Called BrainNet, the network allows the exchange of mental signals from one brain to another, in living people.

MIT informs that the communication system is actually very similar to a game of Tetris, but for three players located in different places.

One of them, the receiver, was in charge of rotating the blocks, although he could only see them at the top of the screen and where they fell.

Two others, the senders, on the other hand, saw the whole screen and had to transmit to the third member of the group if a block had to be turned or not.

The brain signals from the senders were measured by electroencephalograms and transmitted to the receiver through transcranial magnetic stimulation.

Researchers evaluated the performance of BrainNet in terms of (1) Group-level performance during the game; (2) True/False positive rates of subjects’ decisions; (3) Mutual information between subjects.

Five groups of three people took part in this experiment, and the decisions made by the receiver were correct in 81% of the cases.

“Our results raise the possibility of future brain-to-brain interfaces that enable cooperative problem-solving by humans using a ‘social network’ of connected brains,” they say.

The so-called “social network” of brains is clearly still in very rudimentary stages, with only binary “rotate” and “do not rotate” (“yes” and “no”) signals available for now.

“A cloud-based brain-to-brain interface server could direct information transmission between any set of devices on the brain-to-brain interface network and make it globally operable through the Internet, thereby allowing cloud-based interactions between brains on a global scale,” Andrea Stocco and his colleagues say.

“The pursuit of such brain-to-brain interfaces has the potential to not only open new frontiers in human communication and collaboration but also provide us with a deeper understanding of the human brain.”
