New image technique could allow scanners to read minds
(click title for full article)"
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 breakthrough by American scientists took MRI scanning equipment normally used in surgical procedures to observe patterns of brain activity when a subject examined a range of black and white photographs.
Then a computer was able to correctly predict in nine out of 10 cases which image people were focused on - random guesswork would have been accurate only eight times in every 1,000 attempts.
The study raises the possibility in future of the technology being harnessed to visualise 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."

I think if they scanned my head all they'd see is thoughts of bacon. Yum.
Stumbled in and saying hello.
