ABSTRACT
The behavioral effects of intravrnticular 1-micronl injections of adrenaline and noradrenaline (both in a concentration of 30 nmol/micronl) were wxamined in pigeons bearing cannule chronically implanted into the lateral ventricles. Injections of either catcholoamine evoked immediate and intense bouts of feeding behavior, followed by long-lasting incrases in sleep duration (50-90% higher than vehicle-treated subjects) in pigeons given free access to food during the observation period. Pigeons treated with adrenaline or vehicle only, and placed in a cage without the feeder set (food-deprived durngi the observation period), exhibited late increases in exploratory and preening behaviors, and less sleep than controls (vehicle-treated pigeons with free access to food). These data suggest that post-prandial sleep in this situation may represent a by-product of feeding-related processes evoked by both catecholamines
