Document Summary

There are over 30 different areas in the brain that are linked and associated with visual processing. Rodes and cones transmit the information they receive through the optic nerve into the brain. Highly specialized neurons that only respond to vertical or horizontal lines. Where pathway, determine the location of the stimulus, tracks movement. What pathway, determines the identity of the stimulus (a person, animal, car) The act of attending to and processing one item at a time. The act of attending to and processing all items simultaneously. Uses several different areas of the brain at the same time. All we need is three primary light colours to create billions of light colours (blue, red, green) Therefore we must have three different types of light receptors and each is maximally responsive to one primary colour. The brain monitors the three types of light receptors to calculate the hue of the incoming light wave.
