Scientists have created a system that is able to visually reconstruct images that people have seen, by reading their brain activity
In the 1983 film Brainstorm, Christopher Walken played a scientist who was able to record movies of people's mental experiences, then play them back into the minds of other people. Pretty far-fetched, right? Well, maybe not. Utilizing functional Magnetic Resonance Imaging (fMRI) and computer models, researchers at the University of California, Berkeley, have been able to visually reconstruct the brain activity of human subjects watching movie trailers - in other words, they could see what the people's brains were seeing.
