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.

The Supraoptic Nucleus as an Osmoreceptor

Neuroendocrinology, 2008
This ‘Progress’ review is written to challenge the prevalent belief that neurones of the supraoptic nucleus are not involved in the reception of osmotic stimuli. Evidence is presented that these neurones are depolarised by physiological increases in the osmotic pressure of the extracellular fluid.

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.

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.

Electrophysiological evidence for a projection from the arcuate nucleus to the supraoptic nucleus

Neuroscience Letters, 1988
The electrical activity of single neurones in the hypothalamic arcuate and supraoptic nuclei was recorded in urethane-anaesthetized rats. Stimulus pulses applied to the supraoptic nucleus antidromically activated 3 out of 41 cells recorded in the ipsilateral arcuate nucleus, confirming that there is a projection from the arcuate nucleus to the region ...

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 ...

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 ...

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 ...
