English: Supporting Movie S1–Transition. A transition indicates the switch

of a non-autonomous system from one attractor state to another. This movie shows the simulation that Figure 4 is based on. It displays the changing potential landscape as the system transitions from the bistable to the tristable and then the monostable regime (see Figure 2) as auto-activation thresholds are increased. The corresponding phase portrait is shown in the inset on the upper right. Parameter values are displayed in the panel on the lower right. The current state of the system is shown as a black ball. Attractors are marked by blue dots, saddle nodes by red dots with associated separatrices shown as black lines. The history of the trajectory is shown on the phase portrait, colour coded according to which attractor the trajectory is converging towards at

every individual step of the simulation. See main text and Figure 4 for details.
