Representation of the third case
region 0 again we need two steps in that direction and once crossed, we need 3
steps in the direction of the fixed point of region 0, mentioned earlier, to start
again at region 1.
4.2 Case 2
This case is similar to the previous one but parameters are selected in such a
way that the output neuron does never spike, even when there are oscillations.
The plots for this case can be seen on figure 5.
