• The action potential of the renal nerve and the renal blood flow were recorded simultaneously on anesthetized dogs, and following results were obtained.(1) By the common carotid occlusion, the renal nerve discharge was mostly increased. The increase in the discharge was usually accompanied with the renal vasoconstriction, and never with the renal vasodilatation.(2) The increase in the renal vascular resistance during the carotid oc-clusion was depressed by the cutting of the renal nerve.(3) By the release of the occlusion temporary diminution in the renal nerve discharge and the renal vasodilatation were observed.(4) By the stimulation of the central end of the divided cervical vagal nerve, the response in the renal nerve discharge was various. The increase in the discharge was accompanied with the renal vasoconstriction, while the de-crease in the discharge with the renal vasodilatation.(5) During the carotid occlusion and the vagal stimulation, a significant correlation was observed between the changes in the blood pressure and renal vascular resistance in the group with the increased discharge.
