Fig. 5. Stable rhythmic activity recovery only requires one fixed point.

Fig. 5

(a) Phase plane showing both the V-nullcline (dV/dt = 0) and mKd-nullcline (dmKd/dt = 0) during bouting phase. The system’s trajectory (thick curve) shows a limit cycle in the absence of additional fixed points. (b) Membrane potential changes over time show bouting and a stable recovery of bursting activity
