Document Summary
Chapter 7: mechanisms of perception: hearing, touch, smell, taste and. The sensory areas of the cortex are considered to be 3 fundamentally different types: primary sensory cortex receives most of its input directly from the thalamic relay nuclei of that system. Most input to areas of association cortex comes from the secondary sensory cortex. The interactions between the 3 types of sensory cortex and among other sensory structures is characterized by 3 major principles: hierarchical organization, functional segregation and parallel processing. Sensation: is the process of detecting the presence of stimuli. Perception: is the higher-order process of integrating, recognizing, and interpreting complete patterns of sensations. Was once assumed that the primary, secondary and association areas of a sensory system were each functionally homogeneous (meaning that all areas functioned the same) Research shows that there is functional segregation each area contains functionally distinct areas that specialize in different kinds of analysis.
