Carotid sinus baroreceptor activity in the nonhuman primate.
The carotid sinus of eight adult Macaca fascicularis monkeys was functionally isolated from the circulation and perfused with Krebs-Henseleit solution. The impulse activity in 65 carotid sinus baroreceptor fibers from the left carotid sinus nerve was studied during nonpulsatile perfusion and was compared with the impulse activity in 68 fibers from 10 adult mongrel dogs. Curves relating the disc...
متن کاملChronic isolation of carotid sinus baroreceptor region in conscious normotensive and hypertensive rats.
We have developed a chronic technique to isolate the carotid sinus baroreceptor region in the conscious rat model. Our technique, when used in conjunction with other methods, allows for the study of the control of arterial pressure, heart rate, and cardiac output by the carotid sinus baroreceptor reflex in conscious, unrestrained rats. The performance of our technique was evaluated in two strai...
متن کاملRapid baroreceptor resetting in chronic hypertension. Implications for normalization of arterial pressure.
The purpose of this study was to examine the ability of baroreceptors of renal hypertensive rabbits to reset rapidly during acute changes in arterial pressure. The carotid sinus (CS) was vascularly isolated and baroreceptor activity was recorded during slow ramp increases in CS pressure in hypertensive (one-kidney, one wrap; 127 +/- 3 mm Hg) and normotensive (one-kidney, no wrap; 85 +/- 3 mm Hg...
متن کامل1294 Carotid Sinus Baroreceptor Reflex in Dogs With Experimental Heart Failure
We have previously demonstrated a decrease in baroreceptor discharge sensitivity in dogs with experimental heart failure. In the present study, we determined the sensitivity of the carotid sinus baroreceptor reflex in dogs with pacing-induced heart failure. The carotid sinus baroreceptor reflex sensitivity was determined by pressurizing one carotid sinus with all other baroreceptor and cardiopu...
متن کاملReflexes from the aortic baroreceptor fibers in the cervical vagus of the cat and the dog.
The baroreceptor fibers which arise from the aortic arch course centrally within the vagus nerve in the dog, and they usually follow this path in the cat. Near the origin of the superior laryngeal nerve, a separate branch of the cervical vagus (the cervical aortic nerve) arises. Previously, it was thought that this nerve contained all the important baroreceptor afferents. Aortic baroreceptor fi...
