Shkuropat A. Bioelectrical activity and cerebral blood flow of deaf teenagers

Research object - the functional state of brain of deaf teenagers. Research aim - to find out the features of electric activity and circulation of blood of cerebrum of deaf teenagers. Research methods: electroencephalography, registration EEG in a state of functional calmness and during the functional loadings; reoencephalography. Theoretical and practical results, innovations. It is set that auditory deprivation in teens results in activating of lock-on mechanisms of cerebrum, that comes to light in the increase of the rationed spectral power and intensity of electrogenesis over the range of slow waves. Relative functional insufficiency of activating reticulated structure of mesencephalon and structures which are pacemaker alpha-rhythm is exposed for deaf teenagers. The features of cerebral circulation of blood of deaf teenagers which consisted in diminishing tone of vessels of arterial type are first exposed, increase of capillary perfusion in the system of internal carotid. Confirmation of the phenomenon of surplus material well-being of functions is got, which is observed at tension of the adaptation systems and takes place for deaf teenagers in grain the functional state of cerebrum. The got results are created by pre-conditions of individual approach in relation to diagnostics and prognostication of adaptation possibilities of deaf teenagers with the purpose of optimization of the state of health, rehabilitation program, ground of the adequate mode of studies and rest development.
