Simulations of the model in the case when the initial condition is a Gaussian. The figures represent the evolution in time of the firing rate $r(t)$ of the model for a non constant external influence ${\sigma }_0(t)=I_0+I_{1}sin(\omega t)$. In the first plot $I_0=10$, $I_1=10$, $\omega =2$, in the second plot $I_0=10$, $I_1=10$, $\omega =5$ and in the third plot $I_0=10$, $I_1=10$, $\omega =10$. The potential jump size is $h=5$, the coupling parameter—$J=3$ and the basic current—$I_b=-1$
