Neurons in the hypothalamic paraventricular nucleus send collaterals to the spinal cord and to the rostral ventrolateral medulla in the rat
The hypothalamic paraventricular nucleus (PVN) projects to the rostral ventrolateral medulla (RVLM) and to the intermediolateral cell column (IML) of the spinal cord. The present study determinedExpand

Intravenous angiotensin II induces Fos-immunoreactivity in circumventricular organs of the lamina terminalis
Conscious rats were infused intravenously with either angiotensin II (30-55 pmol/kg/min), isotonic saline or phenylephrine for 2 h, then killed. Fos was identified by immunohistochemistry in theExpand

Efferent neural projections of angiotensin receptor (AT1) expressing neurones in the hypothalamic paraventricular nucleus of the rat.
Angiotensin II acts within the hypothalamic paraventricular nucleus (PVN) to help mediate a number of autonomic and endocrine responses. Evidence is sparse in regard to the particular neuronal cellExpand

A comparison of hypotensive and non-hypotensive hemorrhage on Fos expression in spinally projecting neurons of the paraventricular nucleus and rostral ventrolateral medulla
The protein, Fos, detected immunohistochemically, was used to identify neurons in the brain that were activated after hemorrhage in the conscious rat. Spinally projecting neurons in theExpand

Fos production in retrogradely labelled neurons of the lamina terminalis following intravenous infusion of either hypertonic saline or angiotensin II
The lamina terminalis consists of neurons which are activated by both osmotic and angiotensinergic stimuli and which project axons to many sites including regions of the hypothalamus responsible forExpand

P2X purinoceptor subtypes on paraventricular nucleus neurones projecting to the rostral ventrolateral medulla in the rat
The rostral ventrolateral medulla (RVLM) is essential for the generation of sympathetic nerve activity. The RVLM receives a substantial innervation from the hypothalamic paraventricular nucleusExpand

Microglia activation in the hypothalamic PVN following myocardial infarction
Following a myocardial infarction (MI), inflammatory cytokines are elevated in the brain, as well as in plasma, indicating that inflammation is occurring in the brain in addition to the periphery.Expand

An investigation of the mechanisms of hydrogen sulfide-induced vasorelaxation in rat middle cerebral arteries
Hydrogen sulfide (H2S) is an endogenous mediator with peripheral vasorelaxant effects; however, the mechanism of H2S-induced vasorelaxation in cerebral blood vessels has not been extensively studied.Expand
