Document Summary

Sensation: the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception: the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. The brain receives input from the sensory organs. The brain makes sense out of the input from sensory organs. Bottom-up processing: taking sensory information and then assembling and integrating it. Top-down processing: using models, ideas and expectations to interpret sensory information. Reception: the stimulation of sensory receptor cells by energy (sound, light, heat etc. ) Transduction: transforming this cell stimulation into neural impulses. Transmission: delivering this neural information to the brain to be processed. Our eyes respond to some of these waves. Our brains turn these energy wave sensations into colors. Light from the candle passes through the cornea and the pupil, and gets focused and inverted by the lens.
