Cold-induced glutamate release in vivo from the magnocellular region of the paraventricular nucleus is involved in ovarian sympathetic activation
(2010)
We previously reported that centrally-induced sympathetic activation in response to cold stress is associated with a polycystic ovarian condition in rats, and thyrotrophin-releasing hormone (TRH) released locally from the ...
Cold stress induces metabolic activation of thyrotrophin-releasing hormone-synthesising neurones in the magnocellular division of the hypothalamic paraventricular nucleus and concomitantly changes ovarian sympathetic activity parameters
(BLACKWELL PUBLISHING, 2006-05)
Recent studies suggest thyrotrophin-releasing hormone (TRH) serves as a neurotransmitter and thereby provides a functional vegetative connection between the brain and the ovary. In the present study, magnocellular neurones ...
Endothelin-Mediated Calcium Responses in Supraoptic Nucleus Astrocytes Influence Magnocellular Neurosecretory Firing Activity
(Wiley Blackwell Publishing, Inc, 2012-02)
In addition to their peripheral vasoactive effects, accumulating evidence supports an important role for endothelins (ETs) in the regulation of the hypothalamic magnocellular neurosecretory system, which produces and ...
PARAVENTRICULAR AND SUPRAOPTIC NUCLEI OF THE HYPOTHALAMUS MEDIATE CARDIOVASCULAR RESPONSES EVOKED BY THE MICROINJECTION OF NORADRENALINE INTO THE MEDIAL AMYGDALOID NUCLEUS OF THE RAT BRAIN
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2013-08-02)
The medial amygdaloid nucleus (MeA) is a part of the limbic system and is involved in cardiovascular modulation. We previously reported that microinjection of noradrenaline (NA) into the MeA of unanesthetized rats caused ...
Damage to the central amygdala produces differential encephalic c-fos expression in the water deprivation-partial rehydration protocol
(Elsevier B.V., 2009-12-04)
We investigated the effects of electrolytic damage to the central nucleus of the amygdala on brain c-fos expression and 0.3 M NaCl intake of adult male rats (n=6-12/group) submitted to a cycle of 36 h of water deprivation ...

Activation of the serotonergic 5-HT1A receptor in the paraventricular nucleus of the hypothalamus inhibits water intake and increases urinary excretion in water-deprived rats
(Elsevier B.V., 2008-10-09)
The paraventricular nucleus (PVN) may be considered as a dynamic mosaic of chemically-specified subgroups of neurons. 5-HT1A is one of the prime receptors identified and there is expressed throughout all magnocellular ...
