Approximately 200- 500 data points measured over 30-50s were used to construct a baroreceptor
function curve using Sigma Plot software.
information affects striatal dopamine release measured by voltammetry in rats.
With the use of existing experimental data of the aging human aorta, the researchers were also able to find how the stiffening of the aorta with age causes the baroreceptors
to misinform the central nervous system about blood pressure.
The present study, performed in primarilynormotensive rats, had two objectives: 1) to test the effects of sequential exposure, first to a LNa diet for 7 days and then to a HNa diet for 21 days, in rats with and without partial arterial baroreceptor
impairment (to simulate the prehypertensive SS baroreceptor
systemic phenotype) on SSi and on MAP after 21 days on a HNa diet, and 2) to study the roles of plasma NO bioavailability (pNOB), renal medullary superoxide anion production, and renal mRNA expression of NAD(P)H oxidase and superoxide dismutase (SOD) in such responses.
Influence of smoking on baroreceptor
function: 24 h measurements.
resetting: contribuitions of chronic and acute process.
If neostigmine and atropine are administered simultaneously, cardiac baroreceptor
sensitivity is disrupted at least for 2 hours.
Bradycardia and hypotension occur due to inhibition of nor-adrenaline secretion and increased reflex baroreceptor
As outlined in the introduction section, the relationship between hypoalgesia and cardiovascular reactivity may be mediated by any of the following three basic mechanisms modulated by the hypothalamus (paraventricular nucleus): baroreceptor
reflex arc stimulation, endogenous opioid responsivity, and descending pain-modulating pathways (Bruehl & Chung, 2006; France & Ditto, 1996; McCubbin, 1991).
This theory postulates that fluids within the dentinal tubules are disturbed either by thermal, physical or osmotic changes and these fluid changes or movements stimulate a baroreceptor
which leads to neural discharge.

and chemoreceptor reflexes affecting heart rate and cardiac vagal efferent nerve activity.
