title: [Display of activities of integrative brain mechanisms in its bioelectrical activity].
abstract: Integrative processes taking place in CNS lie in the basis of the activity of the whole brain, i.e. they perform as a system-creating factor; they maintain the system stability, succession of its functioning, regularity of intra-system connections and their reproduction. Can this activity appear in extremely mobile, polyform EEG processes? The results of EEG factor analysis show the existence of the very stable uniform structure of spatial interactions of cortical potentials. This structure can be reproduced from EEG of different adult individuals, as well as of children at various stages of ontogenesis. EEG from any point of the cortex can be represented as a linear combination of only three orthogonal components. These components are the same for all the cortical regions. Especially local, independent fluctuations in EEG constitute less than 10% for adults and not more than 20% for newborns. Apparently, the continuous reflection of oscillations of the whole biopotential field in any point of the cortex reveals in EEG the functioning of a mechanism providing the activity of the brain as a whole.
