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 …

In prior studies, systemic opioid receptor antagonism with naltrexone (NTX) failed to block
flavor preference conditioning by the sweet taste or post-oral actions of sugar despite …

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 …

Sugar appetite is influenced by unlearned attractions to sweet taste and learned responses
to sugars' taste and post-ingestive actions. In rats, sugar-conditioned flavor preferences …

The effects of naltrexone on the expression and acquisition of flavor preferences conditioned
by the postingestive actions of carbohydrates were investigated. Food-restricted rats …

In our prior studies, administration of the opioid receptor antagonist naltrexone did not block
conditioned preferences for a flavor paired with a preferred sugar solution over a flavor …

Sugar and fat appetites are influenced by unlearned and learned responses to orosensory
and post-ingestive properties which are mediated by dopamine (DA) and opioid transmitter …

Different central opioid receptor subtypes participate in the mediation of intakes of simple
(sucrose: μ, κ1 and complex (maltose dextrin: μ) carbohydrates as well as deprivation …

The effects of the general opioid antagonist, naltrexone, on the acquisition and expression of
flavor preferences conditioned by the sweet taste of fructose were examined. Food-restricted …
