A new atlas maps word meanings in the brain

This gif shows a spinning 3D view of one person's cerebral cortex. The color of each voxel indicates its semantic selectivity, or which category of words it is selective for. For example, green voxels are mostly selective for visual and tactile concepts, while red voxels are mostly selective social concepts. White lines show the outlines of known functional brain regions. It's like Google Maps for your cerebral cortex: A new interactive atlas, developed with the help of such unlikely tools as public radio podcasts and Wikipedia, purports to show which bits of your brain help you understand which types of concepts.
