Visual neurons know what is important to us before we do

What is it about?

How do we make sense of the elements surrounding us? Current theories posit that complex perception relies on specialized modules in high-level visual regions of the brain, while early regions only process simple properties like the color or orientation of local parts of the scene. Instead, we have shown that neurons in the first cortical visual region, known as V1, are already sensitive to the presence of subjectively important elements, as early as 50ms from the onset of an image, and long before we recognize these elements as important.
