[Methodological bases of studying vestibular reactions].
The paper outlines the current concepts of the physiological functions of the vestibular system and identifies their contradictions. It suggests that from the standpoint of the theory of functional systems and, in the biocybernetic context, the vestibular apparatus should be regarded as an individual component of the whole static and kinetic system that ensures the coordination of movements, the function of the vestibular apparatus as part of the common afferent current and somatic, sensory, and autonomic reactions as the ultimate result of the whole system's activity.
