Serotonin Rhythm in the Pineal Organ: Control by the Sympathetic Nervous System

Virginia M. Fiske 1

1 Department of Zoology and Physiology, Wellesley College, Wellesley 81, Massachusetts

The serotonin content of the pineal organ of the rat varies diurnally in relation to the photoperiod. When the sympathetic nerves to the pineal are interrupted by the removal of the superior cervical ganglia, no such fluctuation in the serotonin content of the pineal occurs.
