Document Summary
Sensation: the detection of some aspect of a stimulus in the environment. Perception: the way in which we (our brains) interpret the information that is gathered by the senses. Primary sensory cortex: first part of the cortex that receives information relayed from the senses through the thalamus; sends information to secondary sensory cortical areas. Secondary sensory cortex: receives most of its information from primary sensory cortex; highly interconnected; receives information from other areas of the secondary sensory cortex; sends information to association cortex. Association cortex: any area of the cortex that receives information from more than one sense. Sensory systems are characterized by hierarchical organization. Each level of the organization contains functionally distinct cortical areas. The processing of sensory information occurs in parallel throughout the cortex. Analogous to the organization of a large business. Further up in hierarchy, jobs become more complex; involves integration of more and varied information. Further down the hierarchy, jobs become more specific.
