U.S. scientist operates colleague’s brain from across campus
NEW YORK, (Reuters) – Scientists said yesterday they have achieved the first human-to-human mind meld, with one researcher sending a brain signal via the Internet to control the hand motion of a colleague sitting across the Seattle campus of the University of Washington. The feat is less a conceptual advance than another step in the years-long progress that researchers have made toward brain-computer interfaces, in which electrical signals generated from one brain are translated by a computer into commands that can move a mechanical arm or a computer cursor – or, in more and more studies, can affect another brain. Much of the research has been aimed at helping paralyzed patients regain some power of movement, but bioethicists have raised concerns about more controversial uses.
