Document Summary
sensation the detection of the elementary properties of a stimulus: i. e. brightness, colors, warmth, and sweetness. perception the detection of the more complex properties of a stimulus, including its location and nature; involves learning: both inanimate and animate objects. Seeing the color red is sensation, seeing a red apple is perception. sensory mechanisms visual, auditory, gustatory, olfactory, and somatosensory systems. sense organs detect stimuli provided by light, sound, odor, taste, or mechanical contact with the environment: information about these stimuli is transmitted to the brain through neural impulses. action potentials carried by the axons in sensory nerves. Task of sense organs is to transmit signals to the brain that are coded in such a way as to represent faithfully the events that have occurred in the environment. Task of the brain is to analyze this information and reconstruct what has occurred.
