Document Summary

Chapter 7 mechanisms of perception: hearing touch smell taste and attention. Excteroceptive sensory systems: the auditory, somatosensory, olfactory, and gustatory systems. The visual system is the most thoroughly studied sensory system and most understood. Each of the other systems are organized like the visual system in fundamental ways. The primary sensory cortex: area that receives most of its input from the thalamic relay nuclei of that system. Secondary sensory cortex: most of the input from the primary sensory cortex. Association cortex: any area that receives input from more than one sensory system. The interactions of these three types of sensory cortex are characterized by three major principles: Sensory system from receptors thalamic nuclei primary sensory cortex secondary. System whose members can be assigned to specific levels or ranks in relation to one another. Usually done on the basis of the specificity and complexity of their function.
