Separate groups of food-deprived rats were given 2h access to food after receiving bilateral
nucleus accumbens infusions of the muscarinic antagonist scopolamine methyl bromide (at …

Intra-nucleus accumbens (Acb) infusion of cholinergic muscarinic antagonist, scopolamine
(10μg/0.5 μl), markedly reduced fat intake elicited by intra-Acb treatment of the μ-opioid …

These experiments tested whether nucleus accumbens muscarinic or nicotinic acetylcholine
receptor activation is required for rats to learn to lever press for sucrose. Muscarinic …

Rationale Previous work has shown that stimulation of GABAergic, opioid, or dopaminergic
systems within the nucleus accumbens modulates food intake and food-seeking behavior …

Pharmacological blockade of muscarinic receptors in the nucleus accumbens reduces food
intake and instrumental behaviors that are reinforced by food delivery. Nucleus accumbens …

The mesolimbic dopamine (DA) system is known to play a role in cue-mediated reward-
seeking for natural rewards and drugs of abuse. Specifically, cholinergic and glutamatergic …

Rationale Stimulation of ventral tegmental area (VTA) muscarinic acetylcholine receptors
(mAChRs) is implicated in feeding. Objective To investigate the effects of mAChR blockade …

Mesolimbic dopamine (DA) is a critical component of the brain circuitry regulating behavioral
activation and effort-related processes. Although nucleus accumbens (NAc) DA depletions …

We have demonstrated previously that injections of 6, 7-dinitroquinoxaline-2, 3-dione into
the nucleus accumbens shell (AcbSh) elicits pronounced feeding in satiated rats. This …

Extracellular levels of acetylcholine (ACh) were measured in the nucleus accumbens (NAC),
striatum (STR), and hippocampus (HIPP) using microdialysis in 30‐min intervals before …
