Component: interface

IStimC = Istim

Component: membrane_potential

\frac{d}{d t} (Vm) = \frac{Istim - Iion}{Cm}

u = \frac{Vm - Vr}{Vp - Vr}

a = \frac{Vth - Vr}{Vp - Vr}

Component: ionic_current

Iion = k u (u - a) (u - 1.0) + r u

Component: recovery_variable

\frac{d}{d t} (r) = eps (- r - (k u (u - (a + 1.0))))

eps = epsilon + \frac{mu1 r}{mu2 + u}

Component: active_tension

\frac{d}{d t} (Ta) = e (kTa u - Ta)

e = \{\begin{matrix} 10.0 e0 if u < 0.05 \\ 1.0 e0 otherwise \end{matrix}
