For the first time, an international team of neuroscientists has transmitted a message from the brain of one person in India to the brains of three people in France.
The team, which includes researchers from Harvard Medical School’s Beth Israel Deaconess Medical Center, the Starlab Barcelona in Spain, and Axilum Robotics in France, has announced today the successful transmission of a brain-to-brain message over a distance of 8,000 kilometres.
“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 one of the team, Harvard’s Alvaro Pascual-Leone in a press release. “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?'”
The team achieved this world-first feat by fitting out one of their participants – known as the emitter – with a device called an electrode-based brain-computer (BCI). This device, which sits over the participant’s head, can interpret the electrical currents in the participant’s brain and translate them into a binary code called Bacon’s cipher. This type of code is similar to what computers use, but more compact.
