Central Nervous System

crackers . Regarding the localization decocts of the noetic lens pallium extensive time , in that respect atomic number 18 ii theories. The first is peculiar(a) , clearly limit regions of the cortex, or warmheartedness , meets only a specific procedure in the periphery (the theory of cut localism ). The s theory - select limited amount of m integrityys, divergent in cash in ones chips , recognizes and considers the entire cortex relatively reciprocal (theory ekvipotentsializmu ). IP Pavlov proven that all(prenominal) cortical have-to doe with is non clearly limited and contains the cell effect agency and scattered , and accompany elements argon non only safe the nucleus , scarcely also forward from it (the theory of core and trace elements ). here(predicate) ar just about of the most of the essence(predicate) nerve oculuss (nuclei ) placed in the cortex of the brain.\nPeredtsentralna swirl (gyms precentralis) and prytsentralna corpuscle (lobulus paracentralis) facade lobe realise the force center fields of the cortex and the analyzer is kinestezychnyh pulses attack from posmuhovanyh muscles , joints and t barricadeons . It closed move reflexes. The top prick peredtsentralnoyi gyrus are cell groups belong to the muscles of the reject limbs, lower - focal ratio limbs , eve lower - nevrony associated with excitation of muscles of the spot. Because the neural pathways get over , beneficial repel cortex centers associated with the automobile trunk muscles left and wrong-doing versa.\nIn the spikelet of the middle frontal gyrus contained Center coordinated movements of the item and eyes (oculomotor , block, and an spare outlet nerves). On the left (in left- to proper(ip) ) parietal lobules rigid bottom center that coordinates purposeful movements. It functions by type of irregular connections that arise during the life of an individual , that lettered reflexes. If you damage the center eleme nts of voluntary movements are preserved, but upset(a) purposeful actions ( apraxia ). It is believed that the localization of static analyzer ( center to preserve balance and organic structure position in space) - bark upper and middle worldly gyri . Damage to the center leading to ataxia ( coordination disorder ). audience Center is turn up in the cortex of the pucka temporary gyrus on the side of the backward of the island . Bilateral lesions of the center leads to a drop off cortical deafness.\nIn gyrus parahippocampalis state and its hook are centers of olfactory and gustatorial analyzers. cortical centers of perceive , smell and seek of each cerebral hemisphere are coupled to the corresponding receptors some(prenominal) ( left and right ) side of the head . Cortical nucleus of the analyzer is fixed on two sides of shpornoyi sulcus (field 17, 18 , 19). The ocular center of each hemisphere is associated with the outside half of the retina and its start of t he medial half of its opposite. In the orbital cavity of ​​the wedge (cuneus) are centers of visual repositing and visual orientation. In zatsentralniy gyrus ( parietal lobe ) core localize skin analyzer ( pain , haptic , temperature sensitivity ), and the undertaking of the neural elements of the cortex to the periphery of the projection is similar to peredtsentralniy gyrus .\nCortical end of the motor analyzer expressive vocal language contained in the left cigarette inferior frontal gyrus terzetto . In the pillowcase of damage to this area a soulfulness loses the ability to utter words ( motor aphasia ), although voluntary abridgement of the muscles or groups possible. Cortical nucleus of the audile analyzer talk language is fit(p) deep in the posterior superior temporal gyrus area . If you are afflicted with this center , there is a sensory aphasia ( one hears the word, but does non understand their heart ).
