Abstract
Summary
The aortic depressor reflex cannot be elicited in anesthetized dogs during continuous carotid sinus nerve stimulation. It is postulated that the blockade of the aortic reflex is due to excitation of unidentified afferent fibers contained in the carotid sinus nerve, which probably do not arise from chemoreceptors and which are apparently not of the classical baroreceptor type since the selective stimulus of increased sinus pressure failed to block the aortic reflex.
