Gene expression in the supraoptic nucleus

Microscopy Research and Technique, 2002
AbstractThe magnocellular neurosecretory cells (MNCs) in the supraoptic nucleus (SON) express multiple kinds of genes, including not only the classical hormones arginine vasopressin (AVP) and oxytocin (OXT), but also other physiologically active substances including neuropeptides, their receptors, and nitric oxide (NO) synthase, the rate‐limiting ...

INTERCOMMUNICATION IN THE RAT SUPRAOPTIC NUCLEUS

Quarterly Journal of Experimental Physiology, 1983
The vasopressin and oxytocin cells of the rat supraoptic nucleus fire in characteristic discharge patterns during hormone release. The present paper discusses the possible role of intercommunication between supraoptic neurones in determining these patterns.

Afferent connections of the rat's supraoptic nucleus

Brain Research Bulletin, 1990
Neurons projecting to the supraoptic nucleus (SON) have been identified following stereotaxic injections of either horseradish peroxidase or fast blue into the SON region of adult rats. The subfornical organ, median preoptic nucleus, organum vasculosum of the lamina terminalis and medial septal nucleus were the source of the largest numbers of ...

Cytoarchitecture of the Supraoptic Nucleus

Neuroendocrinology, 2008
A Golgi-Cox study of the supraoptic nucleus of the adult rabbit has revealed the presence of three major cell types: (1) large multipolar neurons; (2) large bipolar neurons, and (3) small interneurons. The multipolar and bipolar neurons demonstrated regional variation in the rostral and caudal aspects of this nucleus, while the interneurons appeared ...

Assessment of Spike Activity in the Supraoptic Nucleus

Journal of Neuroendocrinology, 2004
AbstractNovel approaches to the characterization of coding carried by spike trains are discussed. Measuring firing frequency alone may only partially reflect spike patterning, and can only quantify changes of the most obvious kind. We have devised a method that combines probabilistic and information approaches to quantify the variability of the ...

Peripartum interneuronal coupling in the supraoptic nucleus

Brain Research, 2002
In the supraoptic nucleus (SON), the incidence of conducting gap junctions (gjs), as indicated by dye coupling, is low in cycling females, but dramatically elevated in nursing mothers. Functionally, this is consistent with the well-established presence of synchronous milk ejection bursts among oxytocin neurons only in the lactating rat.

Quantitative Histochemistry of Rat Supraoptic Nucleus

1971
1. The activities of 2 enzymes of the hexose-monophosphate shunt and the enzymes of the Golgi apparatus were measured by quantitative histochemical methods in histologically pure supraoptic nucleus. 2. The activities of the Golgi-associated TPPase and NDPase seem to be reliable parameters of neurosecretory activity. 3.

Ultrastructural localization of GABA in the supraoptic nucleus and neural lobe

Neuroscience, 1987
Antibodies directed against the neurotransmitter gamma-aminobutyric acid (GABA) enabled the ultrastructural localization of GABA in conventional glutaraldehyde fixed and osmium postfixed material of the rat supraoptic nucleus and neural lobe. GABA was visualized using immunogold postembedding staining in axonal profiles that terminate on dendrites ...

ANTIDIURETIC MATERIAL IN THE SUPRAOPTIC NUCLEUS

Endocrinology, 1945
Two FUNCTIONS have been attributed to the supraoptic nuclei of the hypothalamus: trophic innervation of the neurohypophysis and secretion. The first is well established, and according to Magoun and Ranson (1939) “few connections in the nervous system rest upon the volume of supporting evidence which has been brought forward for that between the ...

Direct catecholaminergic projection from nucleus tractus solitarii to supraoptic nucleus

Brain Research, 1988
To determine whether the supraoptic nucleus (SON) receives a direct projection from catecholamine cells of the nucleus tractus solitarii (NTS), retrograde transport of rhodamine-tagged latex microspheres was combined with a procedure for the fluorescence histochemical visualization of catecholamines.
