PSYCH 10 Lecture Notes - Lecture 6: Lateral Geniculate Nucleus, Optic Chiasm, Sense Of Balance
Document Summary
Pupils dilate to let in more light or let in less light. Accommodation - changing shape of lens to be more focused (sharp) Images projected to the back of the our retina is upside down and flipped horizontally, brain flips it back. Slide 5 photoreceptors - cones and rods translate light energy into action potentials talk to bipolar cells which then talk to the ganglion. Leave the eye and message is sent to brain) send info laterally. Fovea - predominantly cones, higher detail outside of fovea, predominantly rods, almost no cones. Because, our eyes are in different areas, the images that are projected to our retina are slightly different. The brain takes this info and fills in the gap. Mach bands-lateral inhibition edge detection capabilities- our eyes sees the edges and exaggerates it creating an illusion of a gradient in a solid colored block.
