Serotonin Release from Brain Slices by Electrical Stimulation: Regional Differences and Effect of LSD

Abstract
Slices of rat brain which had accumulated tritiated serotonin either in vivo or in vitro were superfused and electrically stimulated. There occurred a marked release of the exogenous amine and, to a lesser extent, its deaminated metabolites, which varied with the region of brain tested and was inhibited by lysergic acid diethylamide.
