| Abstract: | Origins of vestibular efferent fibers to ampulla of semicircular canals in cats were examined using retrograde transport of horseradish peroxidase. The anterior canal was innervated from bilateral parvocellular reticular nucleus (PCRN), contralateral gigantocellular reticular nucleus and ipsilateral lateral reticular nucleus (LRN); the lateral canal, from ipsilateral PCRN and LRN as well as ipsilateral lateral vestibular nucleus; and the posterior canal, from bilateral PCRN and ipsilateral medial and lateral vestibular nuclei. |
