Humans just got a step closer to being able to think a message into someone else’s brain on the other side of the world: in a first-of-its-kind study, an international team of researchers has successfully achieved brain-to-brain transmission of information between humans.
The team, comprising researchers from Harvard Medical School teaching affiliate Beth Israel Deaconess Medical Center, Starlab Barcelona in Spain, and Axilum Robotics in Strasbourg, France, used a number of technologies that enabled them to send messages from India to France — a distance of 5,000 miles (8046.72km) — without performing invasive surgery on the test subjects.
“We wanted to find out if one could communicate directly between two people by reading out the brain activity from one person and injecting brain activity into the second person, and do so across great physical distances by leveraging existing communication pathways,” said co-author Alvaro Pascual-Leone, MD, PhD, director of the Berenson-Allen Center for Noninvasive Brain Stimulation at Beth Israel Deaconess Medical Center and Professor of Neurology at Harvard Medical School.
“One such pathway is, of course, the internet, so our question became, ‘Could we develop an experiment that would bypass the talking or typing part of internet and establish direct brain-to-brain communication between subjects located far away from each other in India and France ?'”
