Peripartum interneuronal coupling in the supraoptic nucleus
Brain Research, 2002In 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.

ANTIDIURETIC MATERIAL IN THE SUPRAOPTIC NUCLEUS
Endocrinology, 1945Two 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 ...

GABAergic projection from the arcuate nucleus to the supraoptic nucleus in the rat
Neuroscience Letters, 2000Electrical stimulation of the neurones in the hypothalamic arcuate nucleus results in a transient inhibition followed by a marked post-stimulus excitation of magnocellular neurones of the supraoptic nucleus. Microdialysis administration of the gamma-aminobutyric acid agonist (GABA(A)), muscimol, directly into the supraoptic nucleus inhibited both ...

Quantitative Histochemistry of Rat Supraoptic Nucleus
19711. 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.

Dendritic trees of neurones in the rat supraoptic nucleus
Neuroscience, 1982The cytoarchitecture of the rat supraoptic nucleus was studied using the Golgi-Cox method with a neutral red or Cresyl violet counterstain to allow the limits of the nucleus to be determined accurately. A small number of stained neurones were seen in each of the brains sectioned but they were unevenly distributed in the supraoptic nucleus.

Somatic spines in the supraoptic nucleus of the rat hypothalamus
Cell and Tissue Research, 1974Electron microscopic studies of ultrathin serial sections of the perikarya and adjacent neuropil of neurons of the supraoptic nucleus (SON) of the adult male rat revealed varying forms of two types of somatic spines. One type forms synapses with axons passing the cell, the other, without synapses, appears to serve as a buttress or clasp for adjacent ...

Cardiovascular Regulation of Vasopressin Neurons in the Supraoptic Nucleus
Experimental Neurology, 2001This paper reviews the regulation of hypothalamic vasopressin and oxytocin neurosecretory cells in the neural response to plasma volume expansion. Many questions remain unanswered regarding how an increase in volume affects neurohypophysial hormone secretion, what receptors are important in mediating this response, and which neural pathways are ...

Glial Limitans Elasticity Subjacent to the Supraoptic Nucleus
Journal of Neuroendocrinology, 2004AbstractTwo 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

Neuron–glia interactions in the rat supraoptic nucleus
2008The adult hypothalamo-neurohypophysial system undergoes a striking activity-dependent morphological remodelling that modifies the glial enwrapping of its magnocellular neurons. Although the functional consequences of such remodelling remain hypothetical, recent evidence has provided new insights into the repercussions of glial environment modifications

Neurosecretory activity in supraoptic nucleus of normal rats
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1966The 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.
