**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.
