Nav1.9 expression in magnocellular neurosecretory cells of supraoptic nucleus

Experimental Neurology, 2014
Osmoregulation in mammals is tightly controlled by the release of vasopressin and oxytocin from magnocellular neurosecretory cells (MSC) of the supraoptic nucleus (SON). The release of vasopressin and oxytocin in the neurohypophysis by axons of MSC is regulated by bursting activity of these neurons, which is influenced by multiple sources, including ...

Neuron–glia interactions in the rat supraoptic nucleus

2008
The 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

Cardiovascular Regulation of Vasopressin Neurons in the Supraoptic Nucleus

Experimental Neurology, 2001
This 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 ...

Nicotine facilitates noradrenaline release in the rat supraoptic nucleus

Neuroreport, 2001
Nicotine injected in the supraoptic nucleus facilitates vasopressin release from the neurohypophysis. Nicotinic acetylcholine receptors have been found not only on vasopressin-producing cell bodies but also on presynaptic nerve terminals in the nucleus. Vasopressin cells receive excitatory synaptic inputs from noradrenergic neurones.

Vasopressin Regulation of Noradrenaline Release Within the Supraoptic Nucleus

Journal of Neuroendocrinology, 2000
The effect of electrically evoked dendritic vasopressin release on noradrenaline release into the hypothalamic supraoptic nucleus was assessed by in vivo microdialysis in conjunction with high pressure liquid chromatography and electrochemical detection.

Neuronal plasticity in the hedgehog supraoptic nucleus during hibernation

Neuroscience, 1989
The purpose of the present study was to identify processes of plasticity in the receptive field of neurosecretory neurons of the supraoptic nucleus during hibernation in the hedgehog, in order to correlate them with the increased neurosecretory activity observed in this nucleus during this annual period.

Hamster supraoptic nucleus: Cytoarchitectural, Morphometric, and three‐dimensional reconstruction

The Anatomical Record, 1994
AbstractBackground: The present paper describes the cytoarchitectonic, morphometric, and three‐dimensional characteristics of the golden hamster supraoptic nucleus (SON) in order to provide an anatomical basis for subsequent morphofunctional studies that use this species as an experimental animal.

Cannabinoids Modulate Synaptic Activity in the Rat Supraoptic Nucleus

Journal of Neuroendocrinology, 2005
AbstractIn the present study, we investigated the effects of the cannabinoid receptor agonist CP55,940 on excitatory and inhibitory synaptic transmission in the rat supraoptic nucleus. Whole‐cell patch clamp recordings were performed on supraoptic neurones in in vitro brain slice preparations. CP55,940 significantly reduced the frequency of spontaneous

Morphological plasticity of the rat supraoptic nucleus – cellular consequences

European Journal of Neuroscience, 2010
AbstractThe supraoptic nuclei of the hypothalamus display a remarkable anatomical plasticity during lactation, parturition and chronic dehydration, conditions associated with massive neurohypophysial hormone secretion. This structural remodeling is characterized by a pronounced reduction of the astrocytic coverage of oxytocin neurons, resulting in an ...

Nuclear fos domains in transcriptionally activated supraoptic nucleus neurons

Neuroscience, 1993
This study has analysed by light and electron microscopy immunolocalization the nuclear pattern of distribution of Fos-related proteins in supraotic neurons. Two experimental models of transcriptional activation have been used: sustained, global transcriptional activation, at relatively near physiological conditions, by six days of chronic intermittent
