title: The temporal organization of the correlational association of neurons of the cat motor cortex.
abstract: The multineuronal activity was recorded in cats with a developed conditioned food-procuring reflex to time. Cross-correlation histograms were plotted on the basis of the impulse activity of individual neurons isolated from the multineuronal activity, and an analysis was made of the distribution in real time of the impulses constituting the peaks on these histograms. The secondary analysis of the histograms made it possible to identify the dynamics of the changes in the functional connections between neurons over the course of the phase of active waiting on the basis of the distribution of coupled impulses. It was demonstrated in simultaneously recorded neuronal pairs that the concentration of coupled impulses was observed at various moments in time. Neuronal pairs, the concentration of whose coupled impulses is found towards the end of the conditioned reflex interval, were noted; this is regarded as the manifestation of a conditioned reflex reaction at the level of interneuronal interaction.
