title: Efferent neurons to the labyrinth of Salamandra salamandra as revealed by retrograde transport of horseradish peroxidase.
abstract: Application of horseradish peroxidase to the severed VIIIth nerve of Salamandra salamandra resulted in heavy bilateral labeling of neurons of the medullary reticular formation. These neurons closely resemble the Mauthner neuron in their widespread dendritic ramification. In most preparations axon collaterals are seen to leave the medulla via the contralateral VIIIth nerve. It is suggested that these neurons are labyrinthine efferents.
