Lecture 16 - Physiology of Visual Perception

Cognitive Science has updated the old adage that, "Eyes are the windows to the soul" to Eyes are the windows to the brain. Visual perception is one of the dominating field of research in cognitive science. Welcome to the world of Visual perception. Indeed we live in a visual world but still research in visual perception is inadequate to completely explain the process. To start off with, in this lecture we will begin with the functionality of photoreceptors (Rods and Cones) in the eyes. We will also talk about how neurochemical impulses is processed by various parts in the eyes, and how these messages are relayed via optic chasm to various areas in the visual cortex that leads to visual perception (colur, form, motion and so on).
