From: Analysis of nonlinear noisy integrate & fire neuron models: blow-up and steady states

Parameter values are and and this corresponds to two steady states. Left: Evolution of the distribution function in time of an initial Maxwellian centered at and with variance 0.005. Right: Time evolution of the firing rate; we observe numerically a blow-up behaviour for an initial data satisfying the condition of concentration around described in Theorem 2.2.
