title: Time-dependent changes in hypothalamic dopamine metabolism during feeding in the rat.
abstract: The accumulation of the dopamine metabolite dihydroxyphenylacetic acid (DOPAC), but not the serotonin metabolite 5-hydroxyindoleacetic acid, in the hypothalamus is increased in rats during the second, third and fourth hours of a four hour period of access to food following a 20 hour period of food deprivation. This metabolic change does not correlate with duration of access to food or with amount of food consumed. These results suggest that increased hypothalamic dopamine metabolism during feeding is not related in any simple way to either the onset or termination of feeding.
