 Bursting is defined by long deterministic excursions outside the basin of attraction, while the interburst duration is defined by the escape induced by random fluctuations.
<clarity>  Bursting is defined by long deterministic excursions outside the basin of attraction, while the interburst duration is defined by the escape induced by random fluctuations.
 Bursting is defined by long deterministic excursions away from the attractor, while IBI corresponds to escape induced by random fluctuations.
