IK_TM1991#
- class brainpy.dyn.IK_TM1991(size, keep_size=False, E=-90.0, g_max=10.0, phi=1.0, V_sh=-60.0, method='exp_auto', name=None, mode=None)[source]#
The potassium channel described by (Traub and Miles, 1991) [1].
The dynamics of this channel is given by:
\[\begin{split}\begin{aligned} I_{\mathrm{K}} &= g_{\mathrm{max}} * p^4 \\ \frac{dp}{dt} &= \phi * (\alpha_p (1-p) - \beta_p p) \\ \alpha_{p} &= 0.032 \frac{(15 - V + V_{sh})}{(\exp((15 - V + V_{sh}) / 5) - 1.)} \\ \beta_p &= 0.5 * \exp((10 - V + V_{sh}) / 40) \end{aligned}\end{split}\]where \(V_{sh}\) is the membrane shift (default -63 mV), and \(\phi\) is the temperature-dependent factor (default 1.).
- Parameters:
g_max (
Union[float,TypeVar(ArrayType,Array,Variable,TrainVar,Array,ndarray),Initializer,Callable]) – The maximal conductance density (\(mS/cm^2\)).E (
Union[float,TypeVar(ArrayType,Array,Variable,TrainVar,Array,ndarray),Initializer,Callable]) – The reversal potential (mV).method (
str) – The numerical integration method.name (
str) – The object name.
