[EEG correlation and cortical neurons spike activity during elaboration of a defensive conditioned reflex].
Elaboration of electro-defensive conditioned reflex to light in rabbits has shown, that the values of summary cross-correlation coefficients between EEG and impulse activity of cortical neurones do not change significantly as compared to the control. In these conditions does not change either the part of the neurones that have a significant correlation of their impulse discharges with any configuration of the EEG wave. During 6--10 days of conditioning there occurs a decrease in the amplitudes of both positive and negative EEG oscillations, connected with unit discharges in the neocortex. An EEG quantum has being recorded, i. e. a depolarization potential, directly connected with the generation of spikes by the studied nervous elements.
