["Conditioned states" of cortical cells]. 1983

U G Gasanov, and G Kh Merzhanova, and V B Dorokhov

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.

UI MeSH Term Description Entries

D002540 Cerebral Cortex The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
