iaf_chxk_2008 is an implementation of a spiking neuron using IAF dynamics with
conductance-based synapses . It is modeled after iaf_cond_alpha with the addition
of after hyperpolarization current instead of a membrane potential reset.
Incoming spike events induce a post-synaptic change
of conductance modeled by an alpha function. The alpha function
is normalized such that an event of weight 1.0 results in a peak current of 1 nS
at t = tau_syn.
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
V_th double - Spike threshold 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_ex double - Rise time of the excitatory synaptic alpha function in ms.
tau_in double - Rise time of the inhibitory synaptic alpha function in ms.
I_e double - Constant input current in pA.
tau_ahp double - Afterhyperpolarization (AHP) time constant in ms.
E_ahp double - AHP potential in mV.
g_ahp double - AHP conductance in nS.
ahp_bug bool - Defaults to false. If true behaves like original model implementation.
