Identifying images by watching the brain

In the latest development in the field of neuroimaging, researchers have watched the brain of someone watching an image, and were actually able to perform reasonable reconstructions of the image. Researchers had already demonstrated that they are able to recognize which image a person was looking at when given a limited collection of pictures. Separately, it has been determined that the visual cortex contains a rough map of the eye's retina, implying a degree of spatial organization. The authors of the new paper cite previous results where researchers have identified small images (3x3 pixels) with over 50 percent accuracy simply by following the activity of the visual cortex. The new work significantly ups the ante by moving to 10 x 10 pixel black-and-white images, which are big enough to represent alphabetic characters.
