Differential transmission in the superior cervical ganglion of the cat.
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.
