Scientists 'inject' information into monkeys' brains
Scientists 'inject' information into monkeys' brains In an experiment with science fiction implications, two neuroscientists say they have managed to introduce information directly into the premotor cortex of monkeys. PHOTO CREDIT: Christoph Hitz/NYT When you drive towards an intersection, the sight of the light turning red will make you step on the brake. This action happens due to a chain of events inside your head. Your eyes relay signals to the visual centres in the back of your brain. After those signals get processed, they travel along a pathway to another region, the premotor cortex, where the brain plans movements. Signalling the brain Now, imagine that you had a device implanted in your brain that could shortcut the pathway and 'inject' information straight into your premotor cortex. That may sound like an outtake from The Matrix. But now two neuroscientists at the University of Rochester, USA say they have managed to introduce information directly into...
