[Cellular mechanisms of conditioned reflex integration]

The paper deals with the formation of cellular mechanisms of integration in the course of conditioned reflex elaboration. Primary integration consists in an interaction between the effects of the conditioned (CS) and unconditioned (US) stimuli on neurons, which leads to a stable connection between them. The subsequent, final integration consists in the joining up of these cells into special populations with common functional properties in relation to the paired stimuli. Primary integration is achieved either by the mechanism of addition of the elaborated reaction to the CS to the response to the US, or by joining an adequate reaction to the CS of the elaborated response to the US. The final integration is apparently achieved by the mechanisms of transmition from one neuron to another of the formed connection between the paired stimuli along one path common for the association as a whole.
