Document Summary
Week seven perception: hearing & touch: sensory system organization, auditory system, somatosensory system, pain processing. The hierarchical organization is based on the specificity & complexity of the task & function of the specific level. Primary sensory cortex: an area of sensory cortex that receives most of its input directly from the thalamic relay nuclei of one sensory system. Secondary sensory cortex: areas of sensory cortex that receive most of their input from the primary sensory cortex of one sensory system or from other areas of secondary cortex of the same system. Association cortex: any area of the cortex that receives input from more than one sensory system. The former model was simple, hierarchical, functionally homogenous & serial. The current model is hierarchical, functionally segregated & parallel. Sensory systems are: 1 hierarchically organized, 2 show functional segregation at each level (ex.
