Electrolytic, kainic acid or sham lesions were made in the arcuate nucleus of the hypothalamus (ARH) in female Wistar rats to investigate the putative role of the ARH in the organization of low (2 Hz) or high (100 Hz) frequency electroacupuncture (EA) analgesia.

International Journal of Neuroscience, 1989
The present study was performed to explore the possible involvement of the arcuate nucleus of hypothalamus (ARH) and beta-endorphinergic pathway in the connection from nucleus accumbens to periaqueductal grey (PAG). It was found that the analgesic effect of morphine administered to nucleus accumbens of the rabbit was significantly attenuated by the ...

Arcuate nucleus of the hypothalamus: Effects of age and sex
The Journal of Comparative Neurology, 1998The arcuate nucleus of the hypothalamus (ARN) is involved in a variety of functions known to be sexually dimorphic and altered by aging. Although the effects of sex and age on the synaptic organization and neurochemistry of the ARN have been extensively analyzed, data regarding sex-related differences and age-induced effects on the total number of ...

Oxyntomodulin (OXM) is a proglucagon-derived peptide that suppresses hunger in humans. There are some differences in its food intake-inhibitory effects among species. The central mechanisms are unclear and it is unknown if OXM is more efficacious in a gallinaceous species that has not undergone as much selection for growth as the chicken. The objective

Neurotensin excites neurons in the arcuate nucleus of the rat hypothalamus in vitro
Brain Research, 1986The effects of neurotensin (NT) on 41 spontaneously active neurons in the rat hypothalamic arcuate nucleus (ARC) were determined using an in vitro brain slice technique. Addition of NT (1 microM to 10 nM) to the perifusing medium allowed the action of known concentrations of NT to be examined.

Leptin, the protein product of the adipose tissue-specific ob (obese) gene (1), reduces the body weight, adiposity and food intake of obese ob/ob mice on peripheral or central injection (2, 3, 4). [125I]leptin binding has been detected in mouse choroid plexus (5), from which a leptin receptor gene was expression cloned (5).

The membrane properties of arcuate nucleus (ARN) neurons and their connections with extranuclear regions were examined in vitro, using intracellular recordings obtained in superfused explants of rat hypothalamus. Current-clamp analysis revealed that the electroresponsive properties of a large proportion of ARN neurons are influenced by the expression ...

Effect of cyproheptadine on neuronal ultrastructure in the arcuate nucleus of the rat hypothalamus
Neuroscience and Behavioral Physiology, 19851. Cyproheptadine depresses neuron function in the hypothalamic arcuate nucleus, to a degree that depends on the total dose administered. 2. Under the influence of cyproheptadine release of synthesized neurohormones from AN neurons is inhibited and this may be one mechanism of its therapeutic effect in Cushing's disease.

Electroacupuncture (EA) has a weight loss effect, but the underlying molecular mechanisms of weight loss with EA have not been fully elucidated. This study aimed to investigate the modulatory effects of EA on the phenotype of hypothalamic microglia in obese mice. A total of 50 male C57BL/6J mice were used in this study.

Evidence That Cell Bodies in the Arcuate Nucleus of the Hypothalamus Are Not Cholinergic
Neuroendocrinology, 1985Central cholinergic pathways have been implicated in the control of pituitary hormone release. Based on studies using acetylcholinesterase (AChE) histochemistry, it has been proposed that the cholinergic neurons controlling hormone release originate in neurons of the arcuate nucleus (AH).
