| Abstract(in English) | We investigate the membrane potential fluctuation of a Hodgkin-Huxley neuron model subject, to white Gaussian noise. When the noise intensity is low, the membrane potential fluctuates around the resting state, while at high intensity, action potentials are generated at a non-zero rate. We capture this transition as a marked widening of the stationary distribution of the membrane potential. Our results show that the transition occurs relatively abruptly as the noisy level is increased. Furthermore, we use a one-dimensional excitable model, referred to as an active rotator, to destribe this transition as a saddle-node bifurcation. We argue that such transitions occur in a large class of excitable systems. |
