ABSTRACT
The retrograde transport of fluorescent substances was used in order to investigate divergent axon collaterals of neurons in the nucleus prepositus hypoglossi (Ph). Fast blue (FB) was injected into the flocculus, paraflocculus and/or the vermis, while nuclear yellow (NY) was injected into the oculomotor nucleus alone or combined with injections in the nucleus of Darkschewitsch, the interstitial nucleus of Cajal and the medial longitudinal fascicle. Within optimal survival time, separate populations of single-labeled neurons of both dyes were found in Ph in all cases. Double-labeled neurons were seen in the rostral Ph following FB injections into the flocculus and the paraflocculus and NY injections restricted to the oculomotor nucleus. The present findings demonstrate that many neurons in the rostral Ph give collateral branches to the cerebellum and to the oculomotor nucleus.
