Document Summary
Optics and how the structure of the eye helps you focus the image on the retina in the back. See a blob at the bottom of the vision if you touch the top of the eye and it will move in the opp. Demonstrate how the image on your retina is flipped upside down and inverted. - directly stimulating retina when you touch the eye- maps onto the vision this way because the brain learns to remap it afterwards. Photoreceptors- transduce photo energy/light energy into a neural impulse or something that the nervous system can understand. The examples of parallel processing start at the very beginning with photoreceptors- represent one level of parall processing and as it gets convelged with other neurons, it becomes more complex. Sensitivity and bleaching- diff. types of photo pigment, have diff. type of sensitivity/levels- and above a certain rnage, they can become bleached- become non-functional- and that is an imp.
