The Role of Central Catecholaminergic Systems in Regulation of Food Intake of Chicks

  To clarify catecholaminergic systems on the regulation of food intake in the neonatal chick, we examined the effects of intracerebroventricular (ICV) injection of prazosin (α1-adrenoceptor antagonist), yohimbine (α2-adrenoceptor antagonist) and benserazide (an inhibitor of L-aromatic amino acid de...

ICV administration of benserazide induced a hypophagia after 60min postinjection (P<0.05). It is suggested that catecholaminergic systems play an important role in the neural regulation of food intake in chicks, especially through α2-adrenoceptor.
