siegert_neuron


Description:
 

siegert_neuron is an implementation of a rate model with the
non-linearity given by the gain function of the
leaky-integrate-and-fire neuron with delta or exponentially decaying
synapses [2] and [3, their eq. 25]. The model can be used for a
mean-field analysis of spiking networks.

The model supports connections to other rate models with zero
delay, and uses the secondary_event concept introduced with the
gap-junction framework.

Parameters:
 

The following parameters can be set in the status dictionary.

rate double - Rate (1/s)
tau double - Time constant in ms.
mean double - Additional constant input

The following parameters can be set in the status directory and are
used in the evaluation of the gain function. Parameters as in
iaf_psc_exp/delta.

tau_m double - Membrane time constant in ms.
tau_syn double - Time constant of postsynaptic currents in ms.
t_ref double - Duration of refractory period in ms.
theta double - Threshold relative to resting potential in mV.
V_reset double - Reset relative to resting membrane potential in
mV.
