Neuropsychologist Alexander Luria is a Pavlovian school whose fundamental concepts are the functional system and the Brain of the three units. The concept of functional systems refers to no longer functions are located, if that factors of a function. These functions (the motor act, language, memory, perception, etc..) Systems Functional composition are complex and variable function. Luria (1973), describes three major brain units involved in any form of higher activity. One unit is related to the regulation, activation and modulation of nerve impulses, the second procures, processes and stores information from the surrounding world, the third unit is mainly related to programming and testing of cognitive operations. Each of these operating units include more organs or cortical areas, which together constitute a neuropsychological. The first unit is formed by the reticular activating system is a set of fibers nerve extends from the spinal cord to the midbrain and cerebral cortex, specifically the limbic system.
Its activation function, attention, control, memory and temporal orientation. Vestibular and proprioceptive systems perform cerebral form of regulation, are responsible for the orientation and integration of data from outside. These systems are centered in the brainstem but includes organs such as the thalamus and cerebellum. The second processing unit includes specific cortical regions in the left and right hemispheres, including the corpus callosum (parietal lobes, temporal and occipital). The sensory input and analysis of data is performed in both hemispheres with different objectives.
The spatial organization (drawings and gestures) are a function of the right hemisphere, while the symbolism and language are the left hemisphere. The third unit involved is the higher-order cognitive functioning (Planning and Implementation). The frontal lobes and the motor cortex are the organs involved in programming. The frontal lobes are related to the formation of ideas, attempts conscious and internalized speech. Much of the spoken language is controlled by the motor cortex and is modified by feedback that serves to check and correct the linguistic expression. The brain's prefrontal area has connections with other systems and exercises executive control (planning, regulation and verification of information). Premotor areas dealing with the kinetic melody of language. Model Features Luria. 1 .- The Luria model covers all uses of language. Includes models of speech production, comprehension, reading, writing, repetition of the name and the influence of language on self-regulation and thought. 2 .- It is completely modular. Does not consider any of the functions of language as psychological entities listed above total. Each is composed of subcomponents. An important feature of the Luria model is that different language tasks often share certain subcomponents. Thus the disruption of a sub produces a disorder in more than one task. 3 .- Each of the subcomponents is located in a different area of the brain. The performance of neuropsychological function is the result of coordinated activity of many brain centers. Are you interested in this item? Download here: Visit:
