This review is part of a special issue dedicated to Opioid addiction, and examines the
influential role of opioid peptides, opioid receptors and opiate drugs in mediating food intake …

Obesity has become a serious epidemic and one of the leading global health problems.
However, much of the current debate has been fractious, and etiologies of obesity have …

A microanalysis of hunger-driven and palatability-driven feeding was carried out after
muscimol-mediated inactivation of two frontal regions in rats, the agranular/dysgranular …

Background Mammalian sires participate in infant care. We previously demonstrated that
sires of a strain of nonmonogamous laboratory mice initiate parental retrieval behavior in …

Circuits that participate in specific subcomponents of feeding (eg, gustatory perception,
peripheral feedback relevant to satiety and energy balance, reward coding, etc.) are found at …

Endogenous neuropeptides are important signaling molecules that function as regulators of
food intake and body weight. Previous work has shown that neuropeptide gene expression …

Amylin is a peptide co-secreted with insulin that penetrates into the brain, and produces
satiation-like effects via actions in the brainstem, hypothalamus, and mesencephalon. Little …

Satiety, rather than all or none, can instead be viewed as a cumulative decrease in the drive
to eat that develops over the course of a meal. The nucleus accumbens (NAc) is known to …

Substantial evidence suggests that pharmacological manipulations of neural serotonin
pathways influence ingestive behaviors. Despite the known role of the nucleus accumbens …

Abstract Central serotonin (5-HT) pathways are known to influence feeding and other
ingestive behaviors. Although the ventral tegmentum is important for promoting the seeking …
