Chemoreceptor discharge rate ( C ). When arterial partial pressures drift from the normal values, the chemoreceptors discharge, and do so until equilibrium is reestablished. The chemoreceptor discharge rate reaches a maximum value, then slowly and with fluctuations decays to zero when learning is finished. Measured in arbitrary values between 0 and 1.
