# hh_cond_exp_traub

Name:
hh_cond_exp_traub - Hodgin Huxley based model, Traub modified.
Description:
      hh_cond_exp_traub is an implementation of a modified Hodkin-Huxley model       (1) Post-synaptic currents    Incoming spike events induce a post-synaptic change of conductance modeled    by an exponential function. The exponential function is normalized such that an    event of weight 1.0 results in a peak current of 1 nS.       (2) Spike Detection    Spike detection is done by a combined threshold-and-local-maximum search: if    there is a local maximum above a certain threshold of the membrane potential,    it is considered a spike.       Problems/Todo:    Only the channel variables m,h,n are implemented. The original    contains variables called y,s,r,q and \chi.

Parameters:
      The following parameters can be set in the status dictionary.       V_m	 double	- Membrane potential in mV    V_T	 double	- Voltage offset that controls dynamics. For default    parameters, V_T = -63mV results in a threshold around    -50mV.    E_L	 double	- Leak reversal potential in mV.    C_m	 double	- Capacity of the membrane in pF.    g_L	 double	- Leak conductance in nS.    tau_syn_ex double	- Time constant of the excitatory synaptic exponential    function in ms.    tau_syn_in double	- Time constant of the inhibitory synaptic exponential    function in ms.    t_ref	 double	- Duration of refractory period in ms.    E_ex	 double	- Excitatory synaptic reversal potential in mV.    E_in	 double	- Inhibitory synaptic reversal potential in mV.    E_Na	 double	- Sodium reversal potential in mV.    g_Na	 double	- Sodium peak conductance in nS.    E_K	 double	- Potassium reversal potential in mV.    g_K	 double	- Potassium peak conductance in nS.    I_e	 double	- External input current in pA.
