Document Summary

Sensation: the sense organs" responses to external stimuli and the transmission of these responses to the brain. Perception: the processing, organization, and interpretation of sensory signals; it results in an internal representation of the stimulus. The study of sensation and perception is the study of the bodily systems that convert stimulus energy into useful information. Perception is often based on our prior experiences, which shape our expectations about new sensory experiences. Stimuli must be coded to be understood by the brain. Transduction: a process by which sensory receptors produce neural impulses when they receive physical or chemical stimulation. Our sensory organs" translations of stimuli"s physical properties into neural impulses is called sensory coding different features are coded by different neural impulse patterns. Sensory receptors, (specialized neurons in the sense organs), pass impulses to connecting neurons when the receptors receive physical or chemical stimulation: connecting neurons then transmit information to the brain in the form of neural impulses.
