Scientists Discovered A Gadget That Enables 3 Brains To Share Thoughts

Researchers from the University of Washington and Carnegie Mellon University have effectively discovered a gadget that allows connecting 3 brains, empowering them to share thoughts and coordinate while playing a Tetris-style game together. The team says it could eventually be used to connect many different minds together, even across the web. Apart from connecting many people, BrainNet could actually teach us more about how the human brain functions on a deeper level.

It works by combining electroencephalography (EEG) and transcranial magnetic stimulation (TMS) where EGG is used for recording the electrical impulses that indicate brain activity, and TMS works primarily to administer information to the brain in a non-invasive way.

“The interface allows three human subjects to collaborate and solve a task using direct brain-to-brain communication.”

In the experiment, three participants were asked to play a Tetris-like game which involved falling blocks where two were ‘senders’ and other “receiver”.

The ‘senders’ brain signals were interpreted using EEG to extract the decisions they made, that is – to rotate a block or not before it was dropped to fill a line. Their decisions were sent via the TMS cap to the ‘receiver’ who then made the judgment call.

The team furthermore demonstrated the scalability of the BrainNet by letting other five groups of three participants to perform the Tetris task. The accuracies were astounding.

“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,” the team noted.
