We’ve used the internet to connect computers, now how about using it to connect our brains? Researchers at the University of Washington have done just that in what they claim is the first ever brain-to-brain interface.
On August 12, researchers Rajesh Rao and Andrea Stocco sent a signal from one person’s brain, over the internet, to remotely control the hand movement of the other individual, making his index finger move on a keyboard.
Rao sat in his lab wearing a cap with electrodes hooked up to an electroencephalography (EEG) machine, which reads electrical activity in the brain. Stocco sat in his lab across campus wearing a swim cap marked with the stimulation site for the transcranial magnetic stimulation (TMS) coil that was placed directly over his left motor cortex, which controls hand movement.
