brain-to-brain interface

brain-to-brain interface

Communicating from one human brain to another. In 2013, the University of Washington demonstrated the first brain-to-brain interface. A researcher playing a computer game wore a cap that sensed brainwaves. He did not have the game controller and could not physically press any buttons. Using only his mind, he pressed the button by thinking about it, and his brain's electrical activity was transmitted to a second researcher in another location, who actually pressed the button. See brain-machine interface.


From Brain to Brain
While playing the game (top), the researcher presses the button with his mind, and the cap senses his brain waves. Unable to view the game, the recipient (bottom), wearing a transcranial magnetic stimulation (TMS) coil over his left motor cortex, felt his finger involuntarily press the button at various times.

In BrainNet, three people play a Tetris-like game using a brain-to-brain interface. This is the first demonstration of two things: a brain-to-brain network of more than two people, and a person being able to both receive and send information to others using only their brain.
The team hopes that these results pave the way for future brain-to-brain interfaces that allow people to collaborate to solve tough problems that one brain alone couldn't solve.
According to the study published in the journal of Scientific Reports, In BrainNet, a platform used for research, three people play a Tetris-like game using a brain-to-brain interface. This is the first demonstration of two things: a brain-to-brain network of more than two people, and a person being able to both receive and send information to others using only their brain.

Researchers think recorded brain waves have the potential to score the mental faculties of murderers, create brain-to-brain interfaces where conscious thoughts are transmitted over the internet and unconsciously enacted by another person or see drones flown by neural impulses.
