Bifurcation diagrams depict the state space of the E-I system in terms of the mean external inputs. a-b Mean-field model and AdEx network without adaptation with up and down-states, a bistable region bi (green dashed contour) and an oscillatory region LC_EI (white solid contour). c-d With somatic adaptation. The bistable region is replaced by a slow oscillatory region LC_aE
