a new scientific mind-reading technique that is able to to accurately predict images being viewed by people, using quite advanced brain activity scanners (fMRI).

"the study raises the possibility in future of the technology being harnessed to visualize scenes from a person's dreams or memory... 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".

first, custom-made software analyzes a subject's visual cortex while they view 1000s of images over 5 hours, to learn how that person's brain codes visual information. then, the decoder is able to predict the brain activity it would expect if the subject is viewing a new set of images.

sounds like a great tool to research how people "visualize" abstract concepts?

C'mon, I believe some people as psychics were born with real ability but now we're led to believe we can be taught this. Also the mystery of the mind still evades science to give an even close understanding as to how it works.

Did they then try this after a month or so had gone by? The intricacies of brain architecture change all the time, there's nothing much impressive about a computer being able to match an fMRI image of a brain state to the same state (and essentially the same image, roughly) a few hours later. Months or years after, based on similarities, would be impressive if not ground breaking.
