Document Summary
You only see what you are concentrated on. Change blindness: attracted to the information that is most relevant to you. Ex. our vision is limited, we focus on what is in the middle (queen) vs. seeing the guy in the background change. The contrast in the middle is what makes it look like these objects do not have the same color, but whenever you cover the middle, you can see they are the same color. Objective: our objective is to understand how the brain sees the world around us. We will learn how neurons represent visual information, and how simple visual perception (such as perception of edge/contrast and color) works. Keep in mind: seeing through the brain is quite different from the physical reality. Lecture outline: light, eye, retina and visual receptors. Visual neurons and their receptive fields: perception of edge and color. Higher order visual processing & attention: light, eye, retina and visual receptors, light is important for vision.
