[The synchronization of EEG rhythms and the holographic theory of memory].

[Article in Russian]

Abstract

M. N. Livanov's idea about the role of synchronization of EEG rhythms in realization of brain functions and holographic theory of memory are two trends in neurophysiology of behavior which develop independently but are really tightly connected. They are unified on the basis of the data concerning the compliance of EEG rhythms and activity of neurons, on the one hand, and the results of mathematical simulation of CNS information processing, on the other. A comparison of slow background and evoked potential oscillations and activity of separate units showed close interrelations of these processes in a broad frequency range of exogenous and endogenous EEG rhythms and polyrhythmia. The role of synchronous convergence of orderly burst and tonic pulse flows in learning was studied in experiments and on a mathematical model of the nervous network. It was found out that in case of synchronous rhythmical potential oscillation and corresponding burst unit discharges in the phase of generalized activation the information fixation was possible in any nervous elements, which simultaneously received pulses from other sources. In the phase of absence of general activation the revealing of images is possible everywhere in nervous elements, which simultaneously received pulses from the other sources. In this phase it is possible to reveal the images fixed in memory in the form of spatially ordered unit pulse flows. These findings develop M. N. Livanov's ideas concerning the functional role of synchronization of slow potential oscillations and give specific evidence for basic propositions of holographic theory.
