NROC64H3 Lecture Notes - Lecture 2: Homonymous Hemianopsia, Dalmatian (Dog), Optic Chiasm
Document Summary
Vision 2: how vision works in its bottom up processing and top down processing. Knowing that this is a dalmatian dog makes it easier to perceive that it"s a dalmatian dog. This shows that the top down processes are important to vision: v1 is in the cerebral cortex. Chiasm and lgn: last week we talked about how light from the visual field is projected through the lens to an eye. Eyes are fixated towards the middle between the green and red bar. The visual field is projected into each of the two eyes. Some people have the notion that the left eye sees the right visual filed and the right eye sees the left visual field. This is not true because the two visual fields overlap. This is what helps us with stereo vision. Most of the visual fields goes into the left and right eye.
