Our eyes are the window to the world, but making sense of the thousands of images that flood us each day is squarely in the purview of the brain – and now researchers say they have created the first interactive map of how the brain organizes these groupings.

The result, achieved through computational models of brain imaging data collected while the subjects watched hours of movie clips, is what researchers call “a continuous semantic space.”

Some relationships between categories make sense (humans and animals share the same “semantic neighborhood”, for example) while others such hallways and buckets are less obvious. But the researchers found that different people share a similar semantic layout.
