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. Sensory coding = our sensory organs" translation of stimuli"s physical properties into neural impulses. Transduction = a process by which sensory receptors produce neural impulses when they receive physical or chemical stimulation. Connecting neurons then transmit information to the brain in the form of neural impulses. Most sensory information first goes to the thalamus, a structure in the middle of the brain. Neurons in the thalamus then send information to the cortex, where incoming neural impulses are interpreted as sight, smell, sound, touch or taste. Haptic sense (touch) dissolved in fluid on the tongue. Molecules dissolved in fluid on mucous membranes in the nose. Taste cells in taste buds on the tongue. Sensitive ends of olfactory neurons in the olfactory epithelium.
