[Interrelationship between spatial synchronization and rhythmic components of the human EEG].
The main object of the work was to elucidate the functional significance of different human EEG rhythms. Cross-correlation and spectral characteristics at the background and during mental work were studied in thirteen subjects by recording from four points of the left hemisphere. ⋯ The alpha-rhythm becomes less pronounced everywhere in parallel to the decrease in synchronism of its fluctuations in different zones; at the same time low-frequency activity (delta-theta) increases both by the amplitude of oscillations and the capacity for its unidirectional shifts over the whole cortex. The least distinct change is observed in the beta-rhythm.
