Steady-state of the AHH model.

(A) Steady-state gating variables , , and time constants , , as functions of in the AHH neuron model for different values. (B) Steady-state values for the transmembrane potential and the gating variables (left), and gating variable time constants at (right), as functions of . Vertical dashed lines indicate , , and (see text for description). In the top panels, the horizontal dashed line indicates mV for . Time constants in units of ms, and in units of .
