| Popis: | Simultaneous bilateral stimulation of the lateral vestibular nucleus in cats demonstrated that nystagmus evoked from each nucleus could be algebraically summated. This precise interaction was destroyed by labyrinthectomy which produced a resting nystagmus contralateral to the lesion. Resting nystagmus could be potentiated or inhibited by stimulating the appropriate nucleus. Atropine eliminated and amphetamine potentiated resting and elicited nystagmus. These data suggest a resting labyrinthine discharge which is necessary for vestibular stability in the intact animal and which enters the ipsilateral vestibular nucleus from which projections—possibly via the reticular formation—inhibit the contralateral lateral vestibular nucleus. |
