Before revision:  We show that, for parameters within the bistable region , a square current pulse can trigger the abnormalsynchronous regime , a process we claim to reproduce features of an epileptic seizure. We can also suppress it, as well. Suppression can be achieved through a current with small amplitude applying on less than 10  %DIF < of neurons.
After revision:  We show that, for parameters within the bistable region , a square current pulse can trigger the abnormalsynchronous regime , a process we claim to reproduce features of epileptic seizures. Then, we show that it is possible to suppress such abnormal synchronisation by applying a small-amplitude external current on less than 10  %DIF < of neurons.
