Level set simulations of the transitions between the amoeboid to fan-shaped and the fan-shaped to oscillatory states.

The transitions are simulated with a constant threshold up to the black line, after which the threshold is gradually lowered, with the red line indicating the progress in time. The transition from amoeboid to fan-shaped is demarcated by the shift in activity from a fluctuating to a constant maxima, while the transition from fan-shaped to oscillatory occurs when the maxima shifts back to a periodic cycle. Scale bars represent 10 μm.
