A mathematical model of pH(i) regulation in central CO2- chemoreception.
In CO2 chemosensitive neurons, an increase in CO2 (hypercapnia) leads to a maintained reduction in intracellular pH (pH(i)) while in non-chemosensitive neurons pH(i) recovery is observed. The precise mechanisms for the differential regulation of pH(i) recovery between these cell populations remain to be identified; however, studies have begun to explore the role of Na+/H+ exchange (NHE). Here, we compare the results of two different formulations of a mathematical model to begin to explore pH(i) regulation in central CO2 chemoreception.
