title: [CORRELATIONS BETWEEN EEG AND RHEOGRAPHIC INDICES OF CEREBRAL BLOOD FLOW IN CHILDREN ON NORTH-EAST OF RUSSIA].
abstract: The purpose of the work was an estimation of correlations between EEG spectral parameters and rheoencephalogram (REG) indicators of cerebral blood flow (CBF) in the group of children of 7-18 years old living in the North-East of Russia. Well-known data were confirmed about age-dependent EEG and REG-CBF indicators dynamics. It was not revealed strong coordination between EEG and REG age-dependent changes in this period of life. This may to our opinion speak of relative independence of development of those systems which reflect itself in EEG and REG--structural functional organization of the brain and cerebral metabolic rate. In a narrow age band 14.8-15.6 years old it was found highly significant positive correlation between EEG theta activity and REG amplitude-frequency parameter--indicating CBF. The hypothesis was suggested explaining this fact from the point of view of the down-regulation mechanism of the brain in the period of energy expensive synthetic processes in puberty period.
