In the present study we evaluated the effect of intracerebroventricular (ICV) administration of naloxone on feeding induced by food deprivation, norepinephrine (NE), muscimol and neuropeptide Y (NPY). Naloxone (200, 100 and 50 micrograms ICV) decreased deprivation-induced feeding. In contrast, only the 200 micrograms dose of naloxone decreased NE-induced feeding and the 200 and 100 micrograms doses decreased muscimol-induced feeding. Eating stimulated by central administration of NPY was potently decreased by doses of naloxone ranging from 10-200 micrograms.
