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 deca...

Zusammenfassung: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 decarboxylase). We found that food intake was significantly suppressed by ICV injection of yohimbine (25 and 50μg) over 60min (P0.05). ICV administration of benserazide induced a hypophagia after 60min postinjection (P
