'Mind-reading device' recreates what we see in our heads

Mind reading could become a reality after scientists unveiled a device which translates what we are seeing in our heads onto a screen.

By monitoring the brain activity of people while they watched Hollywood movie trailers, researchers were able to recreate a moving picture similar to the real footage being played.

While the technology is not yet capable of reading our thoughts, it could eventually lead to ways of translating our dreams and memories onto screen.

If it is refined enough the method could even be used to explore the minds of stroke patients, experts said.

Researchers from the University of California, Berkeley, used MRI scanners to monitor the blood flow in people's brains as they watched films including Madagascar 2, Pink Panther 2 and Star Trek unfold on a screen.

After analysing how the brain's visual centre responded to on-screen movements, the scientists created a computer program which could accurately guess what the person was looking at. more
