THE CAUDAL VENTROLATERAL MEDULLA IS A SOURCE of TONIC SYMPATHOINHIBITION
(Elsevier B.V., 1993-09-03)
The caudal ventrolateral medulla (CVLM) contains neurons that are essential for the elaboration of the sympathoinhibitory effects of baroreceptor afferent stimulation. To determine if neurons in the CVLM also mediate a ...
Acute and chronic electrical activation of baroreceptor afferents in awake and anesthetized subjects
(Associação Brasileira de Divulgação Científica, 2009)
Electrical stimulation of baroreceptor afferents was used in the 1960's in several species, including human beings, for the treatment of refractory hypertension. This approach bypasses the site of baroreceptor mechanosensory ...
Evidence that blood pressure remains under the control of arterial baroreceptors in renal hypertensive rats
(Associação Brasileira de Divulgação Científica, 2009)
The purpose of the present study was to determine the range of the influence of the baroreflex on blood pressure in chronic renal hypertensive rats. Supramaximal electrical stimulation of the aortic depressor nerve and ...
Gill denervation eliminates the barostatic reflex in a neotropical teleost, the tambaqui (Colossoma macropomum)
(2016-08-01)
The baroreflex is one of the most important regulators of cardiovascular homeostasis in vertebrates. It begins with the monitoring of arterial pressure by baroreceptors, which constantly provide the central nervous system ...
AFFERENT PATHWAYS INVOLVED in CARDIOVASCULAR ADJUSTMENTS INDUCED BY HYPERTONIC SALINE RESUSCITATION in RATS SUBMITTED TO HEMORRHAGIC SHOCK
(Lippincott Williams & Wilkins, 2009-08-01)
The peripheral hyperosmolarity elicited by intravenous infusion of hypertonic saline (HS) can be beneficial in treating hemorrhagic shock. However, the neural mechanisms involved in this resuscitation remain unknown. the ...
Baroreceptor reflex and integrative stress responses in chronic fatigue syndrome
(Lippincott Williams & WilkinsPhiladelphiaEUA, 2003)
Cardiovascular and ventilatory interactions in the facultative air-breathing teleost Pangasianodon hypophthalmus
(2019-08-01)
All vertebrates possess baroreceptors monitoring arterial blood pressure and eliciting reflexive changes in vascular resistance and heart rate in response to blood pressure perturbations imposed by, e.g., exercise, hypoxia, ...
Effect of simvastatin in the autonomic system is dependent on the increased gain/sensitivity of the baroreceptors
(Wiley PeriodicalsMalden, 2013-08)
A number of mechanisms have been proposed to explain the pleiotropic effect of statin therapy to reduce sympathetic outflow in cardiovascular disease. We tested the hypothesis that statin treatment could improve baroreflex ...
Effect of baroreceptor denervation on the autonomic control of arterial pressure in conscious mice
(WILEY-BLACKWELL, 2011)
This study evaluated the role of arterial baroreceptors in arterial pressure (AP) and pulse interval (PI) regulation in conscious C57BL mice. Male animals, implanted with catheters in a femoral artery and a jugular vein, ...
