We're not quite at the stage where we can communicate brain to brain with our fellow humans, but we may be on our way to communicating with other species. Or at least controlling them, thanks to a new, non-invasive interface developed by scientists at Harvard Medical School.
A team led by Seung-Schik Yoo, an assistant professor of radiology, has created a brain-to-brain interface (BBI) that allows a human controller to move a portion of a rat's body just by thinking about it, all without invasive surgical implants.
Brain-to-computer interfaces (BCIs) are becoming more common; that is, interfaces that allow a human to control a computer or gadget with thought using electroencephalography (EEG). A bi-directional interface -- one that allows communication from the computer back into the brain -- is a little trickier; without applying some sort of physical stimulation, it's impossible for a computer to force a brain to send out the signals that control limb movement, for example. … Read more
