A pharmacological analysis of neurally induced inhibition of carotid body chemoreceptor activity in cats.


Experiments were performed to determine the mechanism by which centrifugal impulses in the carotid sinus nerve (CSN) reduce the frequency of impulse traffic in afferent chemoreceptor fibers from the carotid body in cats. Recordings of chemoreceptor activity were made from single- or few-fiber preparations dissected off the CSN, while the remainder of the… (More)
