New Device Reads Minds Pretty Well


Canadian researchers say they can glean simple preferences from a person’s brain by shining near-infrared light into the noggin.

The study, reported in the Journal of Neural Engineering, demonstrated the ability to decode a person’s preference for one of two drinks with 80 percent accuracy by measuring the intensity of near-infrared light absorbed in brain tissue, the scientists said in a statement today.

“This is the first system that decodes preference naturally from spontaneous thoughts,” says Sheena Luu, a University of Toronto doctoral student in biomedical engineering who led the work under the supervision of Tom Chau, a specialist in pediatric rehab engineering at the university’s Bloorview Kids Rehab center.

    What about listening to whether or not they go “mmmmmm!” or “blech!” Would that work? Probably with higher accuracy too.

  2. I’ve read some chi/qi studies that suggested that some of the information content that supposedly exists as chi/qi can be transferred to others in the near-infrared spectrum (more specifically, they lost the effects they were measuring when they introduced a near-infrared filter, but not with any of the other visible and non-visible light filters).


    And remember, always apply the 5th Commandment of the Pentabarf.
