Abstract
Both histamine and 4-methylhistamine, after intraventricular injection into normal rats, reduced the levels of serotonin and increased those of 5-hydroxyindoleacetic acid in hypothalamus; after injection into tranylcypromine-treated rats, head twitches were induced which were blocked by antiserotonin agents. 2-Pyridylethylamine, an agonist of histamine H 1 receptors, neither influenced serotonin level in hypothalamus nor evoked behavioural changes. It is concluded that injected histamine may release serotonin from the hypothalamus and that this produces the behavioural changes.
