PSYC 001 Lecture Notes - Lecture 4: Peripheral Vision, Color Vision, Lateral Geniculate Nucleus
Document Summary
Cells of retina: receptors --> bipolar cells--> ganglion cells. How to design a color perception system in biology. You can shoot red, green, and blue and make your eyes think that it is another color. Phones and televisions use this but with very small pixels so you can"t see the red,green, and blue. They said can"t imagine a reddish green, or yellowish blue (so maybe there is system that opposes these colors) Afterimages suggest: fatigue red, something fills in green. Vision beyond the retina retina --> lateral geniculate nucleus (part of thalamus) --> visual cortex. As visual system receives this information it breaks it down into components. Cells for orientation (look at dark orientation then show fainter one) Don"t see the original orientation because you loose sensitivity to it for a little after look at the high contrast image. Some cells only shoot off when they see a certain orientation. Cats raised in horizontal strip environment (cells prefer horizontal)
