Shape perception does not require dorsal stream processing

Did you know that our brains can perceive the shape of objects without passing through the dorsal visual stream? Scientists Ayzenberg and Behrmann point out that the global shape of objects can be computed directly in the ventral visual stream, where it contributes to object identification. They use a fascinating analogy of ancient cave paintings to explain this idea. Just like the simple stick figures and coarse outlines captured in 7000-year-old cave paintings at Wadi Sura in Egypt, our brains are capable of perceiving shapes without relying on complex processes. This challenges previous beliefs that shape perception solely depends on dorsal stream processing. The research also connects neuroimaging and deep neural networks to support their argument. It’s an incredibly exciting breakthrough in understanding how our brain processes visual information! Curious to learn more?
