Figure 7. Example of stable, long-lasting, continuous simulation with irregular firing using the stochastic model.

A depolarizing current pulse just above the firing threshold is given. A simulation of 5 seconds is shown to provide evidence that stable solutions are obtained with stochastic differential equations and Brownian motion. The simulation time of this trace with time-step of 10⁻⁵ seconds is ca. 15 seconds. For this simulation σ = 0.5.
