It is well established that opioid systems in the brain exert an important modulatory influence
on food intake. Even before the discovery of the endogenous opioid peptides or the cloning …

Humans eat for many reasons, including the rewarding qualities of foods. A host of
neurotransmitters have been shown to influence eating behavior and some of these appear …

Nucleus accumbens μ-opioid stimulation causes marked increases in the intake of highly
palatable foods, such as a high-fat diet. However, to date there has been little examination of …

Food reward can be driven by separable mechanisms of hedonic impact (food 'liking') and
incentive motivation (food 'wanting'). Brain mu-opioid systems contribute crucially to both …

It is well established that opioid signaling in the central nervous system constitutes a
powerful stimulus for food intake. The role of opioids in determining food preference …

What role do brain dopamine and opioid systems play in the mediation of reward? Do these
neurotransmitter systems mediate pleasure? Are reward and pleasure identical? What …

Palatability is one of the most rewarding aspects of consummatory behavior. Opioids, potent
facilitators of intake of sweet and fat tastants, are thought to mediate hedonics of feeding …

Over the last decades, the importance of food in the development of chronic diseases has
been examined, as well as the medical value of eating healthy. The contribution of the …

Numerous reports have described opioids as peptides involved in the regulation of food
intake. The role of these endogenous substances appears to be linked with reward …
