"The observers of this unusual visual stimulus reported seeing the borders between the stripes gradually disappear, and the colors seem to flood into each other. Amazingly, the image seemed to override their eyes' opponency mechanism, and they said they perceived colors they'd never seen before."

Hacking the Senses: The brain is far more plastic than we commonly realize. Presenting new 'senses' via the old inputs works extremely well, to the point that long-term volunteers are a little lost without their new abilities to feel magnetic north or absolute orientation. Tasting direction; feeling pictures. Fascinating stuff. In a loosely related article, genetically modified mice are able to see the full color range visible to humans, even though the last natural mouse able to see this way died out a hundred million years ago. Add the new sensors, and the brain reconfigures. [via]
