Before revision:  Switching between rest and spiking is mainly determined along the downstroke of the action potential , a dynamical feature lacking in common neuron modelswith reset dynamics. Nonetheless similar derivations can be applied to quadratic integrate-and-fire models. The derived interspike interval distribution is shown to be unimodal, which warrants the future use of meanfield approaches to networks of bistable neurons .
After revision:  Switching between rest and spiking is mainly determined along the downstroke of the action potential , a dynamical feature that is not captured by the commonly used reset neuron models. The deduced spike statistics can help to identify HOM dynamics in experimental data .
