[Characteristics of the oculo-vestibulomotor interaction during experimental asymmetry of the labyrinth].
Eye and head coordination in response to trigger and predictive patterns of the gaze fixation reaction was investigated in 19 healthy men under normal conditions and during unilateral monopolar stimulation of the labyrinths. Transient changes in movement coordination and asymmetry of velocity and amplitude characteristics of oculomotor components which deteriorated regulation of search-information reflexes were detected. Changes in the regulation of eye and head movements in response to experimental asymmetry of labyrinths were followed by short-term visual symptoms of the scillopsia type. This was a result of changes of the gain coefficient in the system of ocular, vestibular and motor interaction. It is postulated that labyrinthine asymmetry is one of the mechanisms of sensory mismatch underlying somatomotor discoordination.
