Opioid signaling has been strongly implicated in driving palatable food consumption. The
nucleus accumbens (NAcc) is one important site of this effect; hyperphagia elicited by …

BEHAVIOR AND PSYCHOLOGY and are dissociable under several circumstances. For
example, drug-addicted individuals report a greater desire to consume a drug over time …

Endogenous opioid signaling contributes to the neural control of food intake. Opioid
signaling is thought to regulate palatability, the reward value of a food item as determined by …

The short-acting opiate antagonist naloxone decreases food intake in three models of
ingestive behavior: free feeding, food-deprivation induced feeding and deoxyglucose …

Opioid signaling in the nucleus accumbens (NAcc) regulates feeding behavior, having
particularly strong effects on consumption of highly palatable foods. Since macronutrient …

Opioid signaling in the nucleus accumbens (NAcc) strongly modulates flavor-based food
choice. To further investigate the role of opioid signaling in taste reward, we used a sensory …

Rationale Evidence has implicated the endogenous opioids, in particular μ-opioid receptors,
in emotional behavior and regulation of reward circuits, especially in the context of heroin …

In our prior studies, systemic administration of the opioid receptor antagonist naltrexone
(NTX) did not block flavor preference conditioning by the sweet taste or post-oral actions of …

The present study evaluated the central effects of ß-funaltrexamine (B-FNA), a non-
equilibrium antagonist of μ-opioid receptors and a reversible agonist of κ-opioid receptors …

In the present study dose-dependent effects of the opioid receptor antagonist naloxone were
investigated on the rewarding effects of sweetened condensed milk (SCM) in four behavioral …
