↵aVh and k are the voltage at half-activation or inactivation and the steepness of the steady-state function. τ is the time constant that is voltage-independent for mNap, h1A, h2A, hLVA, mHVA, h1HVA, h2HVA, and ms. For hNaP, mA, mK, mLVA, h1h, and h2h, τ is voltage-dependent and governed by Equation 14 (a, b, c, and d are in mV, e and f are in ms) or Equation 15 (a and b are in mV, and c is in ms).
