Technique that allows “read” thoughts

British scientists say they managed to “read” the thoughts of healthy volunteers using a brain scan.

Researchers at the University of London showed participants several short films and later were able to predict which of them were thinking the volunteers.

The study, published in the journal Current Biology, offers new information on how memories are recorded.

And we are getting closer, say experts, to create some sort of device to detect that a person is thinking by watching his patterns of brain activity.

For long term research also could help develop treatments for memory loss, say the authors.

Studies in the past had shown that brain scans can predict simple thought processes as distinguishing between colors, objects or places.

But remember past events is a more complex process, researchers say.

More complex

With brain scans scientists at the University of London and had managed to tell where a person was located in a virtual reality room.

The new study was based on that finding, but went much further. The scientists analyzed what is called episodic memory.

“In our previous experiment were analyzing basic memories, as the location of a person in an environment,” explains Dr. Eleanor Maguire, of the Wellcome Trust Center for Neuroimaging, University of London, who led the study.

“But it’s much more interesting to analyze the” episodic memory “, memory processes that are far more complex experiences people including information on where we were, what we were doing and how we felt about it,” he adds.

In the experiment the researchers asked 10 volunteers they looked three short films of people engaged in activities of daily living, such as depositing a letter in the mail or littering in a basket.
