Sensory polymodal integration of the human brain cognitive functions

The article analyzes open access publications from eLibrary.RU and PubMed databases. The author formulates the ideas on the mechanisms of polymodal integration of human cognitive activity and behavior during human interaction with the surrounding world. The paper reveals the main theoretical principles of polymodal integration, aaccording to which the human brain functions combining reflex arcs into a multivariant system of neural connections. The disintegration of the polymodal connection system occurs because of the neural process disintegration underlying somatovegetative pathology. Polymodal human brain integration also synchronizes physiological processes of the body and manifests itself in multivaritive patterns of cognitive activity and behavior. Polymodality and multivariance of correlation between somatovegetative parameters consist in the integrative function of brain neurons, which combine into neural circuits not chaotically, but purposefully, based on the interaction of significant external environmental stimuli, to ensure a conscious body response. Polymodal integration of sensory signals is the basis of all human cognitive activity, cognition of the surrounding reality and social behavior in society. Thus, the general idea on polymodal integration allows us to expand our understanding of the integrative activity of the human brain as a complex multifunctional system “Man in the environment”. The research revealed that physiological and mental processes of awareness of the life events occur at the level of sensory polymodal human brain integration. This knowledge can become a basis for creating new neuropathological models for disruption of the interaction processes between man and the environment, and help us understand the true mechanisms of the higher integrative systems of the human brain.
