Basolateral amygdala opioids contribute to increased high-fat intake following intra-accumbens opioid administration, but not following 24-h food deprivation

► BLA opioid blockade attenuates intra-Acb DAMGO-induced intake of a high-fat diet. ► BLA opioid blockade does not affect high-fat intake following 24-h food deprivation. ► BLA opioids mediate palatability-driven feeding, but not energy-deficit feeding.
