Document Summary
If you know what to see, it is easier for you to see it. You have prior knowledge of what the dogs body shape is roughly. Last week, we talked about bottom up processing. You go from the retina features of visual image the one that you see at the very moment. There are top down effects of prior knowledge. It has been known that in the visual cortex there are a lot of projections going bottom up from the eye lgn v1. There are also a lot of projections backwards. V1 lgn, than the other way around. This most likely has to do with feedback mechanism. Different areas in the visual cortex that has to deal with vision. On the left side there are two versions of the monkey brain. It was much more known about the machark brain than the human brain. The v1 looks a bit strange, it"s a bit flat, like a map.
