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 …

Muscarinic receptor antagonism causes a functional alteration in nucleus accumbens μ-opiate-mediated feeding behavior

ML Perry, BA Baldo, ME Andrzejewski… - Behavioural brain …, 2009 - Elsevier
Intra-nucleus accumbens (Acb) infusion of cholinergic muscarinic antagonist, scopolamine

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 …

Multiple brain sites sensitive to feeding stimulation by opioid agonists: a cannula-mapping study

BG Stanley, D Lanthier, SF Leibowitz - Pharmacology Biochemistry and …, 1988 - Elsevier
Evidence suggests that brain opioid receptorrs of the mu, delta and kappa subtypes may be
involved in the control of feeding behavior. However, limited information is available …

Analysis of opioid receptor subtype antagonist effects upon mu opioid agonist-induced feeding elicited from the ventral tegmental area of rats

N Lamonte, JA Echo, TF Ackerman, G Christian… - Brain research, 2002 - Elsevier
The present study examined opioid receptor (s) mediation of feeding elicited by mu opioid
agonists in the ventral tegmental area using general or selective opioid antagonist …

Feeding induced by opioid stimulation of the ventral striatum: role of opiate receptor subtypes.

VP Bakshi, AE Kelley - Journal of Pharmacology and Experimental …, 1993 - ASPET
Previous work has shown that morphine infusion into the ventral striatum results in marked
hyperphagia in satiated rats. The present investigation was undertaken to determine the …

Striatal regulation of morphine-induced hyperphagia: an anatomical mapping study

VP Bakshi, AE Kelley - Psychopharmacology, 1993 - Springer
Both systemic and intracranial administration of morphine can result in spontaneous feeding
in nondeprived rats. The present investigation was conducted to examine the involvement of …

Lateral septum mu opioid receptors in stimulation of feeding

MT Calderwood, A Tseng, BG Stanley - Brain Research, 2020 - Elsevier
Stimulation of mu opioid receptors using drugs like morphine can increase eating when
injected into multiple brain regions including the lateral septum (LS). The LS has been …

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 …
