Abstract

The feeding behavior of amygdala-lesioned male rats was compared to that of normal controls and amygdala shams after 0- or 24-hr food deprivation and after 24-hr food and water deprivation. Results demonstrated that food deprivation was essential for a significant reduction in 1-hr feeding after dorsomedial amygdala damage and that combined food and water deprivation exaggerated such differences in feeding without producing a significant concomitant reduction in drinking. Findings were discussed in terms of the possible role of the dorsomedial amygdala in the central regulation of deprivation-induced feeding.
