Telepathy: scientists connect THREE brains who can share their thoughts | Science | New

Neuroscientists connected the human brain via a machine, which allowed them to play a shared game of Tetris with their minds.

The machine operates through electroencephalograms (EEGs) that record electrical impulses in the brain and transcranial magnetic stimulation (TMS) – where neurons are stimulated using magnetic fields.

The researchers behind the invention dubbed the BrainNet machine and are convinced that in the future, they could support countless brains able to act essentially by telepathy.

The team from the University of Washington and Carnegie Mellon University wrote in its article in the online journal arXiv: "We present BrainNet which, to our knowledge, is the first direct brain-to-brain interface invasive to several problem solving.

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

To carry out this experiment, scientists have set up two "transmitters" connected to EEG electrodes. They were invited to play a Tetris style game in which they had to decide if the blocks had to be rotated.

This meant that shippers looked at one of two flashing LED lights, each producing different signals in the brain.

The choices were then projected on a 'recipient' who wore a TMS cap that generates the signals of the sender's choice in his brain, which would then rotate the block.

Five different sets of three were responsible for playing the game and the setup produced stunning accuracy – over 81%.

And researchers believe that in the future, many human brains could be linked together to solve major problems on a social network of recent ages.

The researchers conclude in their study: "Our findings raise the possibility of future brain-to-brain interfaces allowing cooperative problem solving by humans using a" social network "of connected brains."
