[Otoneurology (definition, brief historical note, classification)].

The authors consider otoneurology to be an integral constituent part of general otorhinolaryngology. They propose its definition, present a brief historical sketch of this scientific discipline, and describe the principles of classification of the pathological conditions encompassed by this branch of general otorhinolaryngology.

[Effect of vestibular stimuli on visual tracking with a limited tracking sector].

The paper presents the results of studying visual tracking of the targets which moved with a constant amplitude of angular displacement. The tracking was carried out during an interaction of vestibular and optic sensors. The tracking stability was related to the coincidence of the direction of vestibular and optic stimuli.

[Sensory components of optokinetic nystagmus in exposure to the action of angular accelerations].

The relationship between the vestibular and optokinetic nystagmus was investigated using a special vestibulooptokinetic trainer. A correlation between the objective index of the angular velocity of the slow component of the optokinetic nystagmus and concomitant sensory reactions responsible for the visual perception of optokinetic stimuli was examined. It was shown that tolerance of the optokinetic system can be characterized by the differential criterion +/-deltaw that is the difference between the angular velocity of the slow component of the optokinetic nystagmus and the angular velocity of optokinetic stimuli.
