Visual Processing Systems of the Human Brain

Mammalian vision is largely motion-based. You can think of this processing system as the "where."

Primates evolved to see in three colors. This has lead to a new visual processing system tacked on to another side of the brain (like an extra garage). This part of the brain processes form and color. You can think of it as the "what" system.

These two systems in tandem process all the visual stimuli coming in through your retina, rehash it, guesstimate what is happening 16ms from now, and present it to you as what you experience as "seeing."

What you see is not one-to-one what is "real." It's rush job. It looks good for long enough.
