Scientists Connect 3 Human Brains using Brain-to-Brain Interface and Make Them Play Tetris

Neuroscientists from the University of Washington and Carnegie Mellon University have figured out a way to connect three human brains to each other in a "BrainNet" interface ... and make them play Tetris!

The team used "electroencephalograms" (EEGs) to record electric impulses from two human brains and "transcranial magnetic stimulation" (TMS) to deliver information to a third brain. The end result: an interface that allowed three human subjects to collaborate and solve Tetris problems using brain-to-brain communication.

In the test, two "senders" were connected to EEG sensors and communicated to a third person, the "receiver" via a TMS helmet with the ability to send flashes directly to the brain.

The two "senders" could see the game of Tetris being played, the "receiver" could not. The goal: send a message telling the receiver to either rotate or not rotate the Tetris piece, depending on how the game was going.
