Document Summary
The detection of physical energy emitted or reflected by physical objects. Occurs when energy in the external environment or the body stimulates receptors in the sense organs. Sensation is the feeling on your hand the perception is the processing. Process by which the brain organizes and interoperates sensory information. Specialized cells that convert physical energy in the environment or the body to electrical energy that can be transmitted as nerve impulses to the brain. Dendrites of sensory neurons responsible for smell, pressure, pain and temperature. Ex. vision could be poor, but sensors are strong- Principle that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain. Sensory crossover also occurs in synesthesia where stimulation of one sense constantly evokes a sensation in another. Take certain kinds of information and transfer it into knowledge. *- take different kinds of sensation and generate a perception.
