Definition: 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. Using only his mind, he fired the canon by transmitting his brain's electrical activity to a second researcher in another location, who actually pressed the key. The recipient was wearing a transcranial magnetic stimulation (TMS) coil over his left motor cortex. While not being able to view the game, he said he felt his index finger involuntarily move at various times to press the spacebar. See brain-machine interface.
