5-Hydroxytryptophan Decarboxylase in Rat Brain: Effect of Hypothalamic Lesions

Abstract
Section of the medial forebrain bundle within the lateral hypothalamus of the rat reduces the serotonin content and the 5-hydroxytryptophan decarboxylase activity in the brain. The integrity of this fiber tract appears necessary for the maintenance of normal concentrations of the amine and enzyme in the telencephalon.
