Autonomic Innervation from the Aortic Root Ventricular Ganglionated Plexi to the Pulmonary Vein: A Novel Pathway

Background: Autonomic nerve innervation pathway from the ventricular GP to the pulmonary veins (PV) remains unclear. Aim: This study investigates the autonomic innervations from aortic root ventricular GP to the PVs. Nissl's staining and fluorescent dual label staining were performed to determine the neuron structure in the aortic root GP in five dogs. Avidin Biotin Complex (ABC) staining were performed to study the efferent autonomic pathway from the aortic root GP to the PVs.
