Speaking with the help of thought: For the first time, a team of researchers from Harvard University has succeeded in producing a transmission between two people - from brain to brain, separated by a distance of 5,000 kilometers - without any invasive manipulation, reports the Sky News website.
The study involved four subjects aged between 28 and 50, who were in France and India. Three were in France and were chosen to receive the transmission, and one was based in India and was required to transmit the thought.
A participant sitting in India was presented with words and sentences and asked to imagine actions for each piece of information presented to him. For example: "They can move their arms or legs.".
Using external electrodes, the researchers were able to record brain signals and translate them into messages. They sent the messages over the Internet to participants who were in France.
Participants in France were attached to an electromagnetic electrode that stimulated their cerebral cortex and allowed the transmission to pass into the brain. The experiment was a success, and the people in France were able to identify the thoughts of the man in India.
One of the researchers, Alvaro Pascual Leone, said: "We wanted to find out if it is possible to communicate directly between two people by reading the brain activity of one of them, even when they are at great distances. We are currently using the Internet, which sends the broadcast. Our next step will be to check whether it is possible to bypass this technology and achieve direct communication.".
