"We present BrainNet which, to our knowledge, is the first multi-person non-invasive direct brain-to-brain interface for collaborative problem solving," write the researchers.

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

    In the experiment set up by the scientists, two 'senders' were connected to EEG electrodes and asked to play a Tetris-style game involving falling blocks. They had to decide whether each block needed rotating or not.

    To do this, they were asked to stare at one of two flashing LEDs at either side of the screen – one flashing at 15 Hz and the other at 17 Hz – which produced different signals in the brain that the EEG could pick up on.

    These choices were then relayed to a single 'receiver' through a TMS cap that could generate phantom flashes of light in the receiver's mind, known as phosphenes. The receiver couldn't see the whole game area, but had to rotate the falling block if a light flash signal was sent.

Kinda sensationalist headline but seeing things in your minds eye that someone else put there, even if its just a flash of light is pretty trippy.
