Stress-Related Effects of Phoenixin on Nucleus of the Solitary Tract Neurons
… PNX has been implicated in a diverse range of physiological activity, including anxiety-like behavior, nociception, memory retention, and food intake. With a robust pattern of expression to compliment these physiological actions, it is clear that PNX plays a pleiotropic role. The nucleus of …

Neural And Humoral Control Of Regional Vascular Beds Via A1 Adenosine Receptors Located In The Nucleus Of The Solitary Tract
… from our laboratory showed that activation of NTS A<sub>1</sub> adenosine</p> <p>receptors yields variable hemodynamic responses with prevailing pressor and iliac</p> <p>vasoconstrictor responses. These responses are accompanied with differential</p> <p>activation of regional sympathetic …

Cocaine- and Amphetamine-Regulated Transcript Peptide Attenuates Baroreflex in the Rat.
… transcript (CART) was first identified in the rat striatum where levels were upregulated following cocaine or amphetamine administration. A dense plexus of CART-immunoreactive fibers is noted in the nucleus of the solitary tract (NTS). Results from tract-tracing and immunohistochemical …

Arc expression in the parabrachial nucleus following taste stimulation
Researchers have made many approaches to study the complexities of the mammalian taste system; however molecular mechanisms of taste processing in the early structures of the central taste pathway remain unclear. More recently the Arc catFISH (cellular compartment analysis of temporal activity by …

Satiety induced by neuropeptide FF and gastrin in birds
… and hormones regulate appetite. The objective of this research was to determine how two satiety-inducing neuropeptides regulate feeding behavior in avian models. Neuropeptide FF (NPFF) was intracerebroventricularly (ICV) injected into Japanese quail and decreased food intake at a …

Evidence for effects of phoenixin on neurons of the paraventricular nucleus
The paraventricular nucleus (PVN) of the hypothalamus has been implicated in autonomic regulation. Through projections to the pituitary gland, median eminence and hindbrain, the PVN plays a role in stress response and other autonomic functions. Recent findings have indicated that both phoenixin …

Central mechanisms underlying the synergistic anorectic effect of CCK and GLP-1 combination therapy
Combination therapies that enhance the effects of separate peptides while limiting adverse effects constitute a promising strategy to improve the efficacy of pharmacologic-based treatments of diabetes and obesity. Cholecystokinin (CCK) and Glucagon-like peptide-1 (GLP-1) are gut hormones produced …

Neural Control of Sickness Behavior
… infections are essential for survival. Beyond the immune response, animals also induce a set of pleiotropic responses including anorexia, adipsia, lethargy, and changes in temperature, collectively termed sickness, during infections. While these responses have been shown to be adaptive for …

THE MECHANISMS AND PHARMACOLOGY OF NEURONAL NICOTINIC ACETYLCHOLINE RECEPTORS IN THE CENTRAL NERVOUS SYSTEM
… in both cognitive and autonomic processes. In the cognitive domains of the brain, destruction of cholinergic inputs or disruption of nAChR function result in cognitive deficits as observed in Alzheimer's disease, schizophrenia, brain trauma and aging. By contrast, moderate activation of nAChRs …

A Behavioral and Anatomical Analysis of Conditioned Taste Aversion in C57BL/6J and DBA/2J Mice
… aversion (CTA) has been commonly used as a model of learning and memory. Traditionally, CTA approaches have used a paradigm that follows the model of classical conditioning. This involves presentation of a novel tastant, such as sucrose (conditioned stimulus, CS), followed by an intraperitoneal …

Neurochemical and functional characterisation of the Melanin-concentrating hormone system in the rat brain
The central melanin-concentrating hormone (MCH) system has been intensively studied for its involvement in the regulation of feeding behaviour and body weight regulation. The importance of the neuropeptide MCH in the control of energy balance has been underlined by MCH knock out and …

Interrogation of the neural mechanisms by which male and female rats assess aversive and mixed valence stimuli in learning and performing a task
<p>The appropriate evaluation of reward and punishment is critical to mammalian survival, and its disruption contributes to numerous psychiatric illnesses. Few animal models capture this tension and rely on learned fear rather than assessment of affective valence. In contrast, conditioned taste …

Neuroanatomical Maps and Taste Reactivity to Sweet, Umami, and Bitter Taste in the PBN of C57BL/6J Mice
… sour, salty, bitter, sweet, and umami (the savory taste of certain amino acids). In neuroscience research, behavioral testing is used to measure the ability of rodents (including inbred mice) to discriminate between the different taste qualities. Taste reactivity and two-bottle …
