3 people play tetris together using brainwaves alone

A system allows individuals to communicate between each other using rudimentary signals guided by their own brainwaves


Key points from article :

BrainNet developed by University of Washington and Carnegie Mellon University.

Allows three people to communicate using only the power of their brain.

Two senders were fitted with scalp electrodes to record their brainwaves.

Receiver read brainwaves using transcranial magnetic stimulation (TMS).

Trio played a Tetris-style game - but receiver could not see half of screen.

Receiver's visual cortex stimulated if decision was to rotate piece.

Information can be transmitted without verbal or motor assistance.

Could help patients who are unable to speak due to brain injury.

The study was published on the pre-print server arXiv.
