The brain scan that tells you exactly what's on your mind
In tests using brain scanners, researchers were able to guess correctly which one of two images a volunteer was thinking about 80 per cent of the time.
In a separate study last year, scientists in California asked volunteers to look at 1,750 images - and then used MRI scanners to predict correctly in nine out of ten cases which images they were thinking off.
At the time, lead researcher Dr Jack Gallant warned: ‘It is possible decoding brain activity could have serious ethical and privacy implications.
‘We believe that no one should be subjected to any form of brain-reading involuntarily, covertly, or without informed consent.’
Some experts believe that the technology could pave the way for a mind-reading device that creates instant images on a screen showing the objects or scenes the subject is thinking or dreaming about.
