A: The pHi and firing rate responses of an individual SC neuron that was inhibited by hypercapnic acidosis from a chamber control adult rat. B: The pHi and firing rate responses of an individual SC neuron that was inhibited by hypercapnic acidosis in an adult rat adapted to CHx. The top panel shows the experimental protocol used. The second panel shows the pHi response of the SC neuron to hypercapnic acidosis over time, which was a maintained acidification with a lack of pHi recovery. Notice that once the hypercapnic solution was removed, pHi returned back towards initial pHi. The bottom panel shows the firing rate response of the SC neuron to hypercapnic acidosis over time, which was a reversible decrease in response to hypercapnic acidosis.
