PSY493H1 Lecture Notes - Lecture 4: Color Blindness, Color Vision, Retina
Document Summary
From sensation to perception: sensation: the process by which we take physical energy from the environment and turn it into a neural signal. Take light information and turn it into a neural signal in our eyes: perception: how we make sense of these neural signals, energy expensive process to take in the world around you. Gross anatomy of the eye: retina: captures information at the back of the eye, millions of rods and cones in retina -> photoreceptors. Cones: colour vision, high definition, important for seeing things sharply. The reason why we don"t have holes is because we use surrounding information and what the other eye sees to fill it in. The primary projection pathways of the visual system: each eye captures a bit of each side of space. Left captures some of left and some of right. Right captures some of left and some of right.
