Rostral projections from the hypothalamic arcuate nucleus

Brain Research, 1975
The response of neurones in the medial basal hypothalamus to electrical stimulation in the suprachiasmatic/preoptic region has been studied in rats anaesthetised with urethane. Neurones in the hypothalamic arcuate, periventricular, ventromedial and dorsal premammillary nuclei were antidromically activated by the stimulation showing that such cells send

Ovary-Dependent Degeneration in the Hypothalamic Arcuate Nucleus*

Endocrinology, 1980
The effects of estradiol valerate and constant light exposure on the histological appearance of the arcuate nucleus were assessed in female rats. Both of these treatments caused significant increases in the numbers of reactive microglial cells and astrocytic granules in the nucleus.

Cryptochrome-dependent circadian periods in the arcuate nucleus

Neuroscience Letters, 2016
The circadian pacemaker in the suprachiasmatic nucleus (SCN) of the hypothalamus is responsible for controlling behavioral activity rhythms, such as a free running rhythm in constant darkness. Rodents have several circadian oscillators in other brain regions including the arcuate nucleus (ARC).

Neurotensin projections to subfornical organ from arcuate nucleus

Brain Research, 1996
Two series of experiments were done in the rat to investigate whether neurons in arcuate nucleus of the hypothalamus (Arc) containing neurotensin (NT)-like immunoreactivity projected to subfornical organ (SFO). In the first series, the anterograde tract-tracer Phaseolus vulgaris leucoagglutinin (PHA-L) was microiontrophoresed into the region of Arc ...

Identification of harman in the rat arcuate nucleus

NaunynSchmiedeberg's Archives of Pharmacology, 1980
This communication describes the presence of 1-methyl-beta-carboline (harman) in the hypophysiotropic area of the hypothalamus which incorporates the arcuate nucleus. Diethyl ether extracts of borate-buffered arcuate homogenates were subjected to silica column chromatography and thin-layer chromatography (TLC).

Hormonal regulation of the arcuate nucleus melanocortin system

Frontiers in Bioscience, 2007
Over the past century, the hypothalamus has emerged as one of the critical sites involved in energy homeostasis. Degeneration studies in rats performed some six decades ago, first led to identifying hypothalamic subregions controlling food intake and body weight.

Regulation of Arcuate Nucleus Synaptology by Estrogen^a

Annals of the New York Academy of Sciences, 1994
Estrogen modulates the synaptology of the hypothalamic arcuate nucleus during sexual differentiation of the rat brain in both males and females. In males, testosterone of gonadal origin is converted to estrogen in the brain by an enzyme, aromatase, which is also present in females.

Arcuate nucleus projections to brainstem regions which modulate nociception

Journal of Chemical Neuroanatomy, 1991
Anterograde tracing studies were conducted in order to identify efferents from the arcuate nucleus, which contains the hypothalamic opiocortin neuronal pool. Phaseolus vulgaris leucoagglutinin (PHA-L) was stereotaxically iontophoresed into the arcuate nucleus and the terminal fields emanating from the labelled perikarya were identified ...

Arcuate Nucleus Hypoplasia in the Sudden Infant Death Syndrome

Journal of Neuropathology and Experimental Neurology, 1992
Abnormalities in central respiratory control during sleep, arousal and/or cardiac activity have been reported in some infants who subsequently die of the sudden infant death syndrome (SIDS). We postulate that these abnormalities may result from dysfunction of the ventral and ventrolateral medulla, which, based on animal data, is an integrative site for
