[Dominant and reciprocal relationships in the organization of the spatial structure of the biopotential correlations of the brain].

The factor analysis of correlation coefficients of brain potentials spatial-temporal structure revealed the "leading constellations" of neural centers in the coordination system for activity of the human brain hemispheres in resting as well as in functional loads; the reciprocity in organization of potential oscillations in the frontal and occipital brain areas, the reciprocal interrelationships being more obvious in the dominant hemisphere. This factor was shown to depend on the level of activation of the subjects even in a functional state unaltered in respect to other EEG indices. When expecting stimuli demanding a left-hand response, a rearrangement of spontaneous dominant interrelationships to the advantage of the right hemisphere occurs in the EEG.
