tivated or inactivated the channels. Each of these gating variables takes on values
between O and 1, and thus serve to modulate the conductance of their respective ion
channels. The ODE for a generic gating variable, call it w, has the form

(2.2)

where w_oo and τ_w are the voltage-dependent steady-state and time constant functions,
respectively. The standard Hodgkin-Huxley model consists of three gating variables,
m and h for Na⁺ and n for K⁺, shown in Figure 2.2.

Now if we write the circuit diagram for this cell as in Figure 2.3, we obtain a
capacitor and a battery in parallel with one constant resistor (Cl~) and two variable
