Monosynaptic convergence of chorda tympani and glossopharyngeal afferents onto ascending relay neurons in the nucleus of the solitary tract: A high‐resolution confocal and correlative electron microscopy approach
Abstract:Physiological studies suggest convergence of chorda tympani and glossopharyngeal afferent axons onto single neurons of the rostral nucleus of the solitary tract (rNTS), but anatomical evidence has been elusive. The current study uses high‐magnification confocal microscopy to identify putative synaptic contacts from afferent fibers of the two nerves onto individual projection neurons. Imaged tissue is revisualized with electron microscopy, confirming that overlapping fluorescent signals in confocal z‐stacks acc… Show more
