Cytoarchitecture of the rat's supraoptic nucleus

Anatomy and Embryology, 1984
There have been few Golgi studies dealing with the cytoarchitecture of the supraoptic nucleus (SON). This is due in part to resistance of supraoptic neurons to impregnation by Golgi methods. In this study, the structure of the SON was examined in normal S/D rats by using both Nissl and Golgi-silver methods.

Cytoarchitecture of the Supraoptic Nucleus

Neuroendocrinology, 1979
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 ...

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.

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 ...

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.

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.

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 ...

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 ...

Neurosecretory activity in supraoptic nucleus of normal rats

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1966
The secretory rhythm of neurosecretory cells was studied in supraoptic nuclei of normally drinking rats. Both nuclei were divided in five zones, and in each one, the nuclear and nucleolar volumes of 50 neurons were measured. Parallel observations were made on the Nissl material and neurosecretory granules.

Glial Limitans Elasticity Subjacent to the Supraoptic Nucleus

Journal of Neuroendocrinology, 2004
AbstractTwo previous studies from our laboratory have indicated that the ventral glial limitans subjacent to the hypothalamic supraoptic nucleus (SON‐VGL) undergoes a reversible thinning upon chronic activation of the magnocellular neuroendocrine cells (MNCs) of the supraoptic nucleus (SON). Numerous other studies have shown that MNC somata hypertrophy
