Vagal primary afferent terminals in the dorsal motor nucleus of the rat: are they making monosynaptic contacts on preganglionic efferent neurons?

Neurosci Lett. 1986 Aug 29;69(2):126-30. doi: 10.1016/0304-3940(86)90590-2.


After horseradish peroxidase (HRP) application to the cut cervical vagus nerve in rats, labelled primary afferent terminals could be demonstrated in the dorsal motor nucleus at the ultrastructural level by a combined glucose oxidase-silver-gold intensification technique. Some labelled boutons contacted labelled dendrites of preganglionic neurons. Thus, the occurrence of a few monosynaptic primary afferent-preganglionic efferent contacts in the dorsal motor nucleus could be demonstrated.
