A projection from nucleus reticularis tegmenti pontis of Bechterew to the medial vestibular nucleus in rabbits.
This study documents a bilateral projection from nucleus reticularis tegmenti pontis (NRTP) to the rostral aspect of the medial vestibular nucleus (MVN) in rabbits. Horseradish peroxidase injections in rostral MVN produced retrogradely labeled neurons in the caudal half of NRTP; caudal MVN injections produced negative results. This supports the hypothesis that NRTP relays visual input to the vestibular nuclei via an extracerebellar pathway (Precht and Strata 1980), and indicates the importance of examining the contributions of both direct and cerebellar-mediated visual pathways to oculomotor physiology.
