increase of the firing activity of both networks (bursting firing activities). Finally,
as the inhibitory inputs become depolarizing a positive feedback loop between
the population of pyramidal cells and the population of FS interneuron exists.
Then, it was shown that as the value of the reversal potential of the inhibitory
synapses overcome a give threshold, a transition toward seizure-like dynamics
occurs (see figure 3).
