Parameters of repetitively firing neurons at a stimulus of −20 pA/pF for pH 7.4 model neurons, pH 6.0 model neurons, and pH 6.0 model neurons with either pH 7.4 slow inactivation or fast inactivation parameters.

	pH 7.4	pH 6.0	pH 6.0 with pH 7.4 FI	pH 6.0 with pH 7.4 SI
First AP depolarization	41.5 mV	25.8 mV	41.1 mV	25.8 mV
Subsequent AP depolarization	19.8 mV	n/a	17.2 mV	n/a
First AP hyperpolarization	−70.9 mV	−61.4 mV	−70.9 mV	−61.4 mV
Subsequent AP hyperpolarization	−68.9 mV	n/a	−67.9 mV	n/a
Firing frequency	94.3 Hz	0 Hz	94.7 Hz	0 Hz

Measured parameters are the maximal membrane potential reached on the initial depolarization and subsequent depolarization, the minimum membrane potential on the first hyperpolarization and subsequent hyperpolarizations as well as the action potential firing rate.
