Description

iaf_chxk_2008 is an implementation of a spiking neuron using IAF dynamics with

conductance-based synapses [1]. 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.

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

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.
