  1. *) KA activation time constant was fixed at 1.5 ms.
  2. g max  = maximum conductance, V50 = half activation/inactivation voltage, slope = slope factors for the steady-state parameters (Eq. 2) or time constant (Eq. 3), P = order for the steady-state parameter (Eq.2), α and β = activation and deactivation rates for Eq. 3, τ 0  = offset for bell function (Eq. 3).
