The Editors

Brain researchers have for the first time demonstrated one human being remotely triggering physical action in another human being—through thought.

Using brain signaling technology, a researcher imagined moving his finger—not actually moving it—and then, almost instantly, in a separate room, another researcher, wearing a cap that sent magnetic stimulation signals to his brain, involuntarily made the exact same finger-moving motion imagined by his colleague (see “Researcher remotely controls colleague’s body with brain,” USA Today, August 28, 2013).
