PSYC 1000 Lecture Notes - Lecture 9: Moon Illusion, Optic Nerve, Ganglion Cell
Document Summary
Psychology notes chapter 6 part 2: vision, additive vs. subtractive. The eyes: retina (made up of, cones, better job at detecting fine details and colors, rods, dimmer lights and shades of grey. Fovea: whatever you are staring right at gets projected to the fovea, more densely compacted with cones, process, cornea, outer protective layer. Projects image to retina: upside down, rods and cones, converting information into electrochemical impulses that the brain can understand, they have an action potential, bipolar cells, ganglion cells, optic nerve, to the thalamus ix. Cerebral cortex: for more processing, occipital lobe, becomes a perception. The ears: eardrum, hammer, anvil, stirrup, cochlea. Taking the information and turning it into electrochemical impulses that the brain can understand: process, vibrations, auditory canal. Three tiny bones: hammer, anvil, stirrup, cochlea, fluid filled, thin membrane that has tiny hairs (like seaweed) that sway with the fluid, how strong they bend, how they bend, all gets turned into, sound time lag information.
