title: Interaction between the vestibular, optical, and proprioceptive sensory systems during realization of rotary nystagmus.
abstract: Questions related to the rotary nystagmus generation in the different variants of interactions between the vestibular, optical, and proprioceptive sensory systems are considered. A physiological concept of the opto-vestibulo-cervical system is given. The biological expediency of nystagmus is considered. It is proved that nystagmus is the organism's position-finding (orientation) reaction directed to a search for the objects in space aiding human orientation. Certain ideas about the vestibulology and physiology of space perception are discussed in detail from the viewpoint of the integral system approach.
