Electrical Stimulation of the Rabbit’s Aortic Nerve and the Dog’s Carotid Sinus Nerve: A Parameter Study
Much of the present clinical work using stimulation of the carotid sinus nerve (CSN) to lower arterial blood pressure is based on studies of the dog (1). Stimulus parameters have varied, but the nerve has usually been treated as a homogeneous structure. However, Douglas et al (2) have found that a large part of the depressor response to electrical stimulation of the buffer nerves in cats and rabbits is due to small unmyelinated nerve fibers. If distinct nerve fiber populations also exist in the dog, then any variation in stimulus parameters could have important implications.
