Document Summary

There are a lot of ways that we use motion. We use a lot of motion detection in social interaction. Superior colliculus part of the brain stem. info from the retina, came back to the optic nerve, some crossed over, most went to lgn and the thalamus, and some went to superior colliculus. Superior colliculus is an alert system when there are unexpected changes. Something has moved in our view: say a cat moves in a bush, we look really quick because our superior colliculus says, (cid:862)did that (cid:271)ush (cid:373)o(cid:448)e,(cid:863) and then we say oh it"s just a cat. Motion has a high level of attention capture. We can create structure of a stimulus from its motion. As a visual stimulus moves, it can help us organize our perception of that stimulus into a whole object. It helps us identify what the object is.
