"Scientists have developed a mind-reading technique that allows them to accurately predict images being viewed by people, by using scanners to study brain activity...
The study raises the possibility in future of the technology being harnessed to visualize scenes from a person's dreams or memory..."
Writing in the journal, Nature, the scientists led by Dr Jack Gallant from the University of California at Berkeley said: "Our results suggest that it may soon be possible to reconstruct a picture of a person's visual experience from measurements of brain activity alone. Imagine a general brain-reading device that could reconstruct a picture of a person's visual experience at any moment in time."
It will inevitably also raise fears that a suspect's brain could be interrogated against their will, raising the nightmarish possibility of interrogation for "thought crimes..."
