The following paper on neuronal gain in the leaky integrate-and-fire
neuron with conductance synapses has been published by Biological

"Study of neuronal gain in a conductance-based leaky integrate-and-fire
neuron model with balanced excitatory and inhibitory synaptic input"
A. N. Burkitt, H. Meffin, and D. B. Grayden
Abstract:
Neurons receive a continual stream of excitatory and inhibitory synaptic inputs.
A conductance-based neuron model is used to investigate how the balanced component
of this input modulates the amplitude of neuronal responses.
The output spiking-rate is well-described by a formula involving three parameters:
the mean $\mu$ and variance $\sigma$ of the membrane potential and the effective
membrane time constant $\tau_{\mbox{\tiny Q}}$.
This expression shows that, for sufficiently small $\tau_{\mbox{\tiny Q}}$,
the level of balanced excitatory-inhibitory input has a non-linear modulatory
effect on the neuronal gain.
