Monoaminergic afferent neurons in the peripheral visceral reflex arcs.
In cats the distal and proximal stumps of transected postganglionic bundles of the celiac ganglion were studied by the Falck--Hillarp histofluorescence methods 72 hrs after transection. Non-degenerated monoaminergic axon terminals were found in the distal stump. It is assumed that these axons reach the celiac ganglion and inhibit the principal ganglion cells.
