Sexual dimorphism of cardiopulmonary regulation in the arcuate nucleus of the hypothalamus
Respiratory Physiology & Neurobiology, 2017The arcuate nucleus of the hypothalamus (ANH) interacts with other hypothalamic nuclei, forebrain regions, and downstream brain sites to affect autonomic nervous system outflow, energy balance, temperature regulation, sleep, arousal, neuroendocrine function, reproduction, and cardiopulmonary regulation.

Peptides, 2019
Neuropeptide K (NPK) induces satiety in birds and mammals. We demonstrated that in birds this effect was associated with the hypothalamus, but beyond this little is known in any species regarding the central mechanism of action. Thus, this study was designed to identify hypothalamic molecular mechanisms associated with the food intake-inhibiting ...

Topography of the dopamine neurons in the arcuate nucleus of the mouse hypothalamus
Cells Tissues Organs, 1979The distribution of the dopamine (DA) cell bodies was elucidated within the mouse arcuate nucleus by fluorescence histochemistry. The arcuate nucleus was divided into five regions; heterogeneity in distribution and different amounts of DA among the regional areas were demonstrated.

Electroacupuncture (EA) effects on the spontaneous unit activities of 143 neurons in the hypothalamic arcuate nucleus (ARH) which were electrophysiologically identified to project to the median eminence were investigated using anesthetized rats weighing about 300 g.

Infusions of acetaldehyde into the arcuate nucleus of the hypothalamus induce motor activity in rats
Life Sciences, 2009The hypothalamic arcuate nucleus (ARH) is one of the brain regions with the highest levels of catalase expression. Acetaldehyde, metabolized from ethanol in the CNS through the actions of catalase, has a role in the behavioral effects observed after ethanol administration.

It is well known that the opiate peptides, especially the pro-opiomelanocortin (POMC)-related peptide beta-endorphin, stimulate the release of prolactin (PRL) in the rat. In order to evaluate the involvement of PRL on the activity of POMC neurons in the arcuate nucleus, we have studied the effects of the injection of PRL into the third ventricle of ...

Arcuate nucleus of hypothalamus involved in analgesic action of l-THP.
Acta pharmacologica Sinica, 2001To study the role of the arcuate nucleus of hypothalamus in analgesic action of l-tetrahydropalmatine (l-THP).The horseradish peroxidase (HRP) retrograde tracing, HRP retrograde tracing combined with immunohistochemistry, lesion of nucleus, tail-flick test, and intra-PAG injection were used in the present study.HRP retrograde tracing results showed ...

Steroid-dependent lordosis behavior in ovariectomized (OVX) guinea pigs is attenuated by alpha 1- and/or alpha 2-noradrenergic (NE) receptor antagonists. Correlated with the decrease in lordosis after alpha 1-NE receptor blockade by prazosin is a decrease in 'cytosol' progestin receptors in the ventromedial hypothalamic nucleus (VMN).

Oxytocin Nerve Fibers Innervate β-Endorphin Neurons in the Arcuate Nucleus of the Rat Hypothalamus
Neuroendocrinology, 1992Fine, varicose oxytocin-containing nerve fibers have been demonstrated in the hypothalamic arcuate nucleus in rats. Using Phaseolus vulgaris leukoagglutinin as an anterograde tracer, fine neuronal fibers of paraventricular nucleus origin could be seen throughout the arcuate nucleus.

Orexin-A-sensitive site for energy expenditure localized in the arcuate nucleus of the hypothalamus
Brain Research, 2003Orexin-A is a unique hypothalamic neuropeptide that stimulates both food intake and energy expenditure, although orexigenic peptides usually have coordinated effects on fat storage by increasing food intake and decreasing energy expenditure. Here we investigated the site of action of orexin-A-induced thermogenesis in urethane-anesthetized rats ...
