Document Summary
Sensation = the sense organs" responses to external stimuli and the transmission of these responses to the brain (188) Perception = the processing, organization, and interpretation of sensory signals, resulting in an internal representation of the stimulus (188) Sensation detects things and perception constructs information about our environments based on sensations (188) Sensory coding = sensory organs" translations of stimuli"s physical properties into neural impulses (189) There are different neural response patterns to different physical features (189) Sensory coding begins with transduction, where sensory receptors produce neural impulses when they receive stimulation (189) Most sensory information first goes to the thalamus, and information is then sent to the cortex where neural impulses are interpreted as sight, smell, sound, touch, or taste (189) We can identify qualitative differences in stimuli, such as whether something is salty or sweet, because different sensory receptors respond to qualitatively different stimuli (190)
