According to an article in Kurzweil News, researchers have demonstrated the first human brain-to-brain interface. Researchers at the University of Washington have accomplished what they believe to be the first noninvasive human-to-human-brain interface. One researcher was able to send a brain signal via the internet to control the hand motions of another researcher. Previously, researchers at Duke University have demonstrated brain-to-brain communication between two rats (the rodents!), and Harvard University researchers have demonstrated brain-to-brain communication between a rat and a human brain. It is hoped that refined technology could be used, for example, by someone on the ground to help a flight attendant or passenger land an airplane if the pilot becomes incapacitated. Or a person with disabilities could communicate a wish for food or water. It is believed that the brain signals from one person to another would work even if they didn’t speak the same language.
