Scientists To Pull Pictures From Your Brain

September 27, 2009


I know for a fact the government can pull images from a person's brain because they've been probing around in my dome for years, messing with the delicate ecosystem up there. And one time when I was being interrogated I saw a picture of a dinosaur in an agent's file folder, SO I KNOW. Anyway, apparently they've decided to make the technology public knowledge.

Having modeled how images are represented in the brain, the researchers translated recorded patterns of neural activity into pictures of what test subjects had seen.

To construct their model, the researchers used an fMRI machine, which measures blood flow through the brain, to track neural activity in three people as they looked at pictures of everyday settings and objects.

As in the earlier study, they looked at parts of the brain linked to the shape of objects. Unlike before, they looked at regions whose activity correlates with general classifications, such as "buildings" or "small groups of people."

Once the model was calibrated, the test subjects looked at another set of pictures. After interpreting the resulting neural patterns, the researchers' program plucked corresponding pictures from a database of 6 million images.

Soon, everyone will have a photo printer in the back of their head to print off worthwhile images they've seen. Me? I already have one. Don't believe me -- check this stack of pictures. What? Don't act like you've never seen a dinosaur penis before!
