["Conditioned states" of cortical cells].
Experimental data are presented on reorganizations of intra- and interanalyzer functional connections of neurones in the course of conditioning, by interval cross-histograms of two impulse series, and notions on neuronal organization of local and spread conditioned states are formulated. Numerous varieties of the analysis of systemic, interconnected activity of cortical neurones in the process of learning convince of the fact that individual and integrative neuronal functions characterize different qualitative levels of their activity. The integrative function of neurones shows various degrees of complicacy and specialization. The local conditioned state is considered to represent functional integration of neurones in cortical microregions, and the spread conditioned state--as neuronal integration between cortical projection zones. The interaction of neurones in the cortical projection of conditioned stimulus is more multiform and complex than that in the motor cortex. During the elaboration of inhibitory conditioned reflex there occurs a reorganization of the cortical systemic activity in the projection zone of the conditioned stimulus and a decrease of intensity of distant connections.
