Sex differences in pre- and post-synaptic glutamate signaling in the nucleus accumbens core

open access: yesBiology of Sex Differences, 2023
Background Glutamate signaling within the nucleus accumbens underlies motivated behavior and is involved in psychiatric disease. Although behavioral sex differences in these processes are well-established, the neural mechanisms driving these differences ...

Overlapping Prediction Errors in Dorsal Striatum During Instrumental Learning With Juice and Money Reward in the Human Brain [PDF]

open access: yes, 2009
Prediction error signals have been reported in human imaging studies in target areas of dopamine neurons such as ventral and dorsal striatum during learning with many different types of reinforcers. However, a key question that has yet to be addressed is

Obesity is associated with a distinct brain-gut microbiome signature that connects Prevotella and Bacteroides to the brain’s reward center

open access: yesGut Microbes, 2022
The prevalence of obesity has risen to its highest values over the last two decades. While many studies have either shown brain or microbiome connections to obesity, few have attempted to analyze the brain-gut-microbiome relationship in a large cohort ...

Distribution and characterisation of Glucagon-like peptide-1 receptor expressing cells in the mouse brain. [PDF]

open access: yes, 2015
© 2015 The Authors.Objective: Although Glucagon-like peptide 1 is a key regulator of energy metabolism and food intake, the precise location of GLP-1 receptors and the physiological relevance of certain populations is debatable.

The Nucleus Accumbens: A Comprehensive Review [PDF]

open access: yesStereotactic and Functional Neurosurgery, 2015
There is increasing interest among functional neurosurgeons in the potential for novel therapies to impact upon diseases beyond movement disorders and pain. A target of increasing interest is the nucleus accumbens (NAc), which has long been studied as a key brain region mediating a variety of behaviors, including reward and satisfaction. As such, focal

Blunted Cystine–Glutamate Antiporter Function in the Nucleus Accumbens Promotes Cocaine-induced Drug Seeking [PDF]

open access: yes, 2008
Repeated cocaine alters glutamate neurotransmission, in part, by reducing cystine–glutamate exchange via system xc−, which maintains glutamate levels and receptor stimulation in the extrasynaptic compartment.

Increased colonic propionate reduces anticipatory reward responses in the human striatum to high-energy foods [PDF]

open access: yes, 2016
Background: Short-chain fatty acids (SCFAs), metabolites produced through the microbial fermentation of nondigestible dietary components, have key roles in energy homeostasis.

Repeated methamphetamine treatment increases spine density in the nucleus accumbens of serotonin transporter knockout mice

open access: yesNeuropsychopharmacology Reports, 2019
Aim Repeated psychostimulant drug treatment, including methamphetamine, in rodents readily produces behavioral sensitization, which reflects altered brain function caused by repeated drug exposure.

History of early life adversity is associated with increased food addiction and sex-specific alterations in reward network connectivity in obesity. [PDF]

open access: yes, 2019
Background:Neuroimaging studies have identified obesity-related differences in the brain's resting state activity. An imbalance between homeostatic and reward aspects of ingestive behaviour may contribute to obesity and food addiction.

Endogenous Dopamine and Endocannabinoid Signaling Mediate Cocaine-Induced Reversal of AMPAR Synaptic Potentiation in the Nucleus Accumbens Shell [PDF]

open access: yes, 2018
Repeated exposure to drugs of abuse alters the structure and function of neural circuits mediating reward, generating maladaptive plasticity in circuits critical for motivated behavior.
