[Convergence of visual and neck proprioceptives on the vestibulo-ocular reflex arc and the "vestibulo-cerebellum" (author's transl)].

Linked to the vestibular reflex, ontologically the most primitive, nuchal and visual proprioceptive afferent impulses heighten perception of movement and the position of the head and body in space. The final goal of these reflexes appears to be maintenance of the visual axis and of posture. They are under cerebellar control which adapts responses according to sensory interactions, and probably increases reactions when a deficiency exists. Functional exploratory tests in patients with positional or postural vertigo should include the study of responses to separate or combined stimulation of these three types of receptor according to the three planes of the semicircular canals.
