Scientists Now Can Extract Images From Human Brains

Human BrainReports have been coming in from Japan’s ATR Computational Neuroscience Laboratories that researchers have developed a system that can “reconstruct the images inside a person’s mind and display them on a computer monitor.”

It seems that the scientists were able to reconstruct various images viewed by a person just by analyzing changes in their cerebral blood flow. In the process using a functional magnetic resonance imaging (fMRI) machine, the researchers at first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. While the fMRI machine monitored the changes in brain activity, a computer crunched the data and learned how to associate the various changes in brain activity with the different image designs being viewed.
