1. The responses of single afferent fibres of carotid body chemoreceptors to independent changes in arterial O(2) and CO(2) tensions and pH were studied in the cat in vivo.2. The response curve obtained relating chemoreceptor activity to changes in arterial P(O2) was similar to an hyperbola; the frequency of nerve impulses at first decreased rapidly as the P(a,O2) was raised and then more slowly. The arterial P(O2) at which the slow decrease was reached varied among the different fibres; the… CONTINUE READING
