Opposite effects on the ingestion of ethanol and sucrose solutions after injections of muscimol into the nucleus accumbens shell

▶ Injections of muscimol into the AcbSh greatly increase intake of sucrose solutions. ▶ In contrast, intra-AcbSh muscimol significantly suppresses ethanol intake. ▶ Intra-AcbSh muscimol does not have the same effect on intake of all preferred diets. ▶ GABA in the AcbSh may play a role in controlling voluntary ethanol intake.
