Abstract
The afferent nervous activities from the aortic nerve and the carotid sinus nerve were analyzed by the averaging method. The major part of the nervous activity in 1 cardiac cycle appeared during the rising phase at lower blood pressure, whereas the pattern of the nervous activity resembled that of the pulse wave at higher arterial blood pressure. The nervous activity in 1 cardiac cycle increased almost linearly with changes in the systolic arterial blood pressure. The averaged nervous pattern of the carotid sinus nerve differs from that of aortic nervous activities with the former lagging about 20 msec behind the latter. The upstroke of the averaged aortic nervous activity is more rapid than that of the carotid nerves. The carotid sinus baroceptors are more sensitive than the aortic baroceptors to the unit change in blood pressure. The phase shift and the pattern of the bilateral aortic nervous activities resembled each other.
