Chronic hyperammonemia alters motor and neurochemical responses to activation of group i metabotropic glutamate receptors in the nucleus accumbens in rats in vivo

Neurobiology of Disease, 2003
Hyperammonemia leads to altered cerebral function and neurological alterations in patients with hepatic encephalopathy. We studied the effects of hyperammonemia in rats on the modulation by group I metabotropic glutamate receptors (mGluR) of motor and ...

Amylin: A Multi‐Functional Pancreatic Hormone—A Review

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Amylin is a pancreatic beta‐cell hormone that sits at a systems hub connecting key aspects of energy metabolism. Amylin physiologically controls satiation, slows gastric emptying and limits postprandial glucagon release, while its actions also link homeostatic eating controls with reward driven behaviours via defined central nervous system ...

Contributions of Positive Social Interactions to Vocal Learning and Social Cohesion

Ethology, EarlyView.
Birdsong produced in non‐breeding flocks is shaped by a dynamic interplay between intrinsic reward and social feedback. Studies in cowbirds and starlings suggest that positive affective states and opioid‐mediated reward promote song practice, while responses from flock mates, potentially reinforced by dopaminergic mechanisms, refine species‐typical ...

Input from the amygdala to the rat nucleus accumbens : its relationship with tyrosine hydroxylase immunoreactivity and identified neurons. \ud

, 1994
Both tyrosine hydroxylase-positive fibres from the mesolimbic dopamine system and amygdala projection fibres from the basolateral nucleus are known to terminate heavily in the nucleus accumbens.

Opioid-Mediated Astrocyte–Neuron Signaling in the Nucleus Accumbens

Cells, 2019
Major hallmarks of astrocyte physiology are the elevation of intracellular calcium in response to neurotransmitters and the release of neuroactive substances (gliotransmitters) that modulate neuronal activity.

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

Nucleus accumbens response to gains in reputation for the self relative to gains for others predicts social media use

Frontiers in Human Neuroscience, 2013
Our reputation is important to us; we’ve experienced natural selection to care about our reputation. Recently, the neural processing of gains in reputation (positive social feedback concerning one’s character) has been shown to occur in the human ventral
