[The dynamics of superslow oscillations in multineuronal activity and bioelectrical potentials of the cat brain during unreinforced photic stimulation].

The slow changes of the electrocorticogram, the multineuronal activity, the cortical EEG and the cat behaviour were simultaneously observed in chronic experiments before and after light stimulation of different intensity. The slow electrical potentials correlated with changes in the multineuronal activity, the correlation increasing with the amount of recorded neurons. A different character of the slow changes in electrogram (synchronization and desynchronization) and multineuronal activity (excitation and inhibition) in response to the light stimuli, was revealed. The slow electrophysiological processes seem to depend on the light intensity to a lesser extent than the EEG reactions.
