Document Summary

Physical stimulus (matter or energy influencing the body) -> physiological response (chemical/electrical activity within the body) -> sensory experience (subjective sensation/psychological experience) Vision: transforms light energy into neural signals, represents objects in the environment in terms of shape, size, color, and location. Light energy: hue the color experienced. Changes by wavelength: wavelength distance from one peak to the other. The eye: everything is backward and weird and makes no sense, rods. Your peripheral vision is black and white. The brain just compensates with the color you saw when actually looking at that space. 120 million distributed along periphery: cones. Detect fine detail due to density of cones. 6 million cones distributed in that tiny area: works off a chemical called rhodopsin, the amazing eye that us not ours. Can covertly signal to each other for mating. Improves clarity of images in the water: trichromatic theory of vision. Three types of cones sensitive to different wavelengths of light.
