[Influence of the cerebellum on the postural labyrinth reflex--experimental and clinical data].

The subject of the study was to estimate the influence of the cerebellum and the postural labyrinth reflex. The pigeons after hemicerebellectomy or vermis ablation this reflex was analysed during body rotation around sagittal and transversal axis. In the clinical part of observations, stabilometric measure of head motion during balance on the movable platform was performed in patients with supratentorial and cerebellar tumors. The results showed the greatest reflex disturbances in vermis ablation and vermis tumors. In hemispheric tumors of the cerebellum these disorders were slighter, but greater in comparison with supratentorial lesions. The authors stressed the role of the vermis in controlling of the reflex.
