Document Summary

Sensation (from physical events to neural events: sensation. A process by which our sensory receptors and nervous system receive and represent stimulus energy: perception. A process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. Vision: retina the light sensitive inner surface of eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information, rods. Necessary for peripheral and twilight vision retinal receptors that detect black, white, and gray: cones receptor cells that are concentrated near the center of retina function in daylight or well-lit conditions. Detect fine detail and give rise to color sensation. The eye: optic nerve- nerve that carries neural impulses from the eye to the brain. Psy 103, topic 18 + 19: blind spot- point at which the optic nerve leaves the eye, creating a blind spot because there are no receptor cells located there.
