Fig. 3. Modifications of activity and the phase plane during the early stages of the recovery of rhythmic activity.

Fig. 3

Left panels show membrane potential changes over time; right panels show the phase plane with both the V-nullcline (dV/dt = 0) and mKd-nullcline (dmKd/dt = 0) indicated. The system’s trajectories are shown by thick curves. (a) Before decentralization the model cell expresses rhythmic activity (left) that corresponds to a limit cycle in the phase plane (right). (b) Immediately after decentralization the cell falls silent (left), which corresponds to the system’s trajectory converging onto a stable fixed point on the left branch of the V-nullcline
