WebSep 1, 1988 · To determine the usefulness of computed electroencephalographic (EEG) topographic (CET) brain mapping to monitor neurologic function during carotid endarterectomy (CEA), 46 consecutive patients having CEA were monitored preoperatively, intraoperatively, and immediately postoperatively by CET brain mapping and … A topographic map is the ordered projection of a sensory surface, like the retina or the skin, or an effector system, like the musculature, to one or more structures of the central nervous system. Topographic maps can be found in all sensory systems and in many motor systems. See more The visual system refers to the part of the central nervous system that allows an organism to see. It interprets information from visible light to build a representation of the world. The ganglion cells of the retina project … See more Unlike the topographic maps of the senses, the neurons of the motor cortex are efferent neurons that exit the brain instead of bringing information to the brain through afferent connections. The motor system is responsible for initiating voluntary or planned … See more The gustatory system is the sensory system for taste. Like olfaction, taste requires a process of chemoreception. The receptors for taste are taste buds on the tongue. The tongue contains taste receptors, as well as mechanoreceptors. Afferents from taste … See more The auditory system is the sensory system for hearing in which the brain interprets information from the frequency of sound waves, yielding the … See more The somatosensory system comprises a diverse range of receptors and processing centers to produce the perception of touch, temperature, proprioception, and nociception. Receptors are located throughout the body including the skin, epithelia, internal … See more The olfactory system is the sensory system used for olfaction, or the sense of smell. It detects volatile, airborne substances. Most sensory systems spatially segregate afferent input from primary sensory neurons to construct a topographic map that defines the … See more For neurons, it is metabolically costly to make long connections, and the trade-off of connection distance is time. Thus, it is good design to … See more
