  • Title: Presynaptic regulation of the release of catecholamines in the cat hypothalamus.
    Author: Dietl H, Sinha JN, Philippu A.
    Journal: Brain Res; 1981 Mar 09; 208(1):213-8. PubMed ID: 7470925.
    Abstract:
    The posterior hypothalamus of cats was superfused through a push-pull cannula and the release of endogenous catecholamines was determined in the superfusate. Superfusion with yohimbine, isoprenaline, salbutamol or tazolol increased, while superfusion with propranolol decreased, the release of all three catecholamines. Transection of the brain caudal to the hypothalamus inhibited 'resting' and drug-induced release. It is concluded that alpha- and beta-adrenoceptors of the hypothalamus are involved in the regulation of the release of catecholamines.
