Stochastic effects in nonlinear systems
Oscillations are a frequently studied phenomenon in science. Examples of this widespread behaviour range from economy to natural sciences. Neurons also exhibit oscillatory properties. The Hodgkin-Huxley model  and the FitzHughNagumo model [47, 48] belong to the most famous models to describe the dynamics of neurons. The FitzHugh-Nagumo model is used more widely, because the calculations for large networks of neurons are easier to handle with this system. It is also the prototype of an excitable system .
