It’s not the first time scientists have linked humans in a brain-to-brain interface. Last year, a University of Washington scientist successfully sent a brain signal over the internet to control and move the hand of his colleague.
While current brain-to-brain interfaces are rudimentary, scientists envision a more sophisticated version of the technology that could facilitate communication for people who have problems speaking, such as stroke victims.
“We hope that in the longer term this could radically change the way we communicate with each other,” Dr. Giulio Ruffini, a theoretical physicist at Starlab in Barcelona and co-author on the study, told AFP.
