Columbia University scientists use light beam to implant image into mouse's mind

Implanting images into someone's mind sounds more like something that would happen in films such as Inception and Total Recall. But scientists have managed to use beams of light to create an image of something completely unknown in a mouse's brain. The findings suggest that the brain may be more easily moulded than previously thought, and could have a major impact on neuroscience and medicine. The thought of artificially implanting an image inside the mind might sound like a technique used by a hypnotist.
