Aortic nerve-activated cardioinhibitory neurons and interneurons

The American Journal of Physiology
J Schwaber, N Schneiderman

Abstract

Unit activity evoked by electrical stimulation of the aortic and vagus nerves was recorded in the dorsal motor nucleus and nucleus solitarius of unanesthetized rabbits. Cardioinhibitory cells which showed antidromic activation to stimulation of the vagus nerve and synaptic activation to stimulation of the aortic nerve were localized in lateral dorsal motor nucleus 0.5-0.8 mm anterior of the obex. Additionally, units were found that appeared to be interneurons in the medullary pathway subserving baroreceptor reflex effects on cardioinhibitory neurons. These cells were activated by aortic, and usually vagus, nerve stimulation, appeared to be polysynaptically activated, and were located in medial nucleus solitarius rostral to the obex. Neurons reflecting a cardiac rhythm but not activated by aortic nerve stimulation were also observed.
