IK_HH1952v2#
- class brainpy.dyn.IK_HH1952v2(size, keep_size=False, g_max=10.0, phi=1.0, V_sh=-45.0, method='exp_auto', name=None, mode=None)[source]#
The potassium channel described by Hodgkin–Huxley model [1].
The dynamics of this channel is given by:
\[\begin{split}\begin{aligned} I_{\mathrm{K}} &= g_{\mathrm{max}} * p^4 \\ \frac{dp}{dt} &= \phi * (\alpha_p (1-p) - \beta_p p) \\ \alpha_{p} &= \frac{0.01 (V -V_{sh} + 10)}{1-\exp \left(-\left(V-V_{sh}+ 10\right) / 10\right)} \\ \beta_p &= 0.125 \exp \left(-\left(V-V_{sh}+20\right) / 80\right) \end{aligned}\end{split}\]where \(V_{sh}\) is the membrane shift (default -45 mV), and \(\phi\) is the temperature-dependent factor (default 1.).
- Parameters:
g_max (float, ArrayType, Initializer, Callable) – The maximal conductance density (\(mS/cm^2\)).
E (float, ArrayType, Initializer, Callable) – The reversal potential (mV).
method (str) – The numerical integration method.
name (str) – The object name.
