Overlapping striatal sites mediate scopolamine-induced feeding suppression and mu-opioid-mediated hyperphagia in the rat
ML Perry, WE Pratt, BA Baldo - Psychopharmacology, 2014 - Springer
Rationale Intra-striatal infusions of the muscarinic antagonist, scopolamine, markedly
suppress feeding; however, the underlying mechanisms are unclear. Recent findings …

Induction of hyperphagia and carbohydrate intake by μ-opioid receptor stimulation in circumscribed regions of frontal cortex
JD Mena, K Sadeghian, BA Baldo - Journal of Neuroscience, 2011 - Soc Neuroscience
Frontal cortical regions are activated by food-associated stimuli, and this activation appears
to be dysregulated in individuals with eating disorders. Nevertheless, frontal control of basic …

d-Fenfluramine and lorcaserin inhibit the binge-like feeding induced by μ-opioid receptor stimulation of the nucleus accumbens in the rat
SA Blumenthal, WE Pratt - Neuroscience letters, 2018 - Elsevier
Multiple laboratories have shown that the stimulation of μ-opioid receptors in the nucleus
accumbens (NAcc) powerfully increases intake of palatable and high-fat diets. Separate …

Intake of saccharin, salt, and ethanol solutions is increased by infusion of a mu opioid agonist into the nucleus accumbens
M Zhang, AE Kelley - Psychopharmacology, 2002 - Springer
Rationale: Endogenous opioids have been implicated in the hedonic evaluation of food and
palatability. Opioids may also be involved in alcohol intake, as there is a positive correlation …
