Consciousness/Sensation and Perception 03:47 Phototransduction in the Retina Two types of photoreceptor cells in the retina contain light-sensitive pigments that transduce light into neural impulses Cones: detect color, operate under normal daylight conditions, and all us to focus on fine detail Located in center or retina Fovea: an area of the retina where visision is the clearest and there are no rods (just cones) Rods: become active under low-light conditions for night vision Black and white Able to see stars better with corner of eye because rods are located peripherally Blind spot: a location in the visual field that produces no sensation on the retina because the corresponding area of the retina contains neither rods nor cones and therefore has no mechanism to sense light No actually receptors- gateway for axons to transmit info The main pathway from the visual distal stimulus and the proximal stimulus: How visual sensory information “flows” to the occipital lobe Distal stimulus: “thing out there”
