Name:

    iaf_cond_alpha - Simple conductance based leaky integrate-and-fire neuron
      model.

Description:

      iaf_cond_alpha is an implementation of a spiking neuron using IAF dynamics with
      conductance-based synapses. Incoming spike events induce a post-synaptic change
      of conductance modelled by an alpha function. The alpha function
      is normalised such that an event of weight 1.0 results in a peak current of 1 nS
      at t = tau_syn.

Parameters:

      The following parameters can be set in the status dictionary.

      V_m	 double	- Membrane potential in mV
      E_L	 double	- Leak reversal potential in mV.
      C_m	 double	- Capacity of the membrane in pF
      t_ref	 double	- Duration of refractory period in ms.
      V_th	 double	- Spike threshold in mV.
      V_reset   double	- Reset potential of the membrane in mV.
      E_ex	 double	- Excitatory reversal potential in mV.
      E_in	 double	- Inhibitory reversal potential in mV.
      g_L	 double	- Leak conductance in nS;
      tau_syn_ex double	- Rise time of the excitatory synaptic alpha function in ms.
      tau_syn_in double	- Rise time of the inhibitory synaptic alpha function in ms.
      I_e	 double	- Constant input current in pA.
