[Dissociation of vestibular autonomic and sensory reactions]

The studies of healthy people and test subjects with vestibular reception disorders yielded data about relative independence of the vestibulo-autonomic and vestibulo-sensory reactions during routine vestibulometric and tilt tests. The subjects with a changed labyrinthine function showed a higher vestibulo-autonomic stability as compared to those with normal hearing. In both groups the sensory component of vestibular reactions did not differ significantly. Hemodynamic changes were found to modify some parameters of the nystagmic reactions.
