^*‘Extended Hodgkin-Huxley’ description.

Simulation temperature: 31°C. V_½ gives the midpoint of the activation curve; z is the valence, setting the steepness of the activation curve; γ is the symmetry parameter determining the skew of τ(v); the base rate (K) is the leading coefficient of α(V) and β(V);τ_o represents a ratelimiting step in the state transition.
