title: Differential transmission in the superior cervical ganglion of the cat.
abstract: Mechanisms in the superior cervical ganglion resulting in contraction of the nictitating membrane (NM) and dilation of the parasympathectimized pupil were studies in anesthetized cats. Frequency-response curves were  obtained following pregangionic stimulation with NM and pupillary responses recorded simultaneously in the same preparations.
