Fig. 4. Modifications of activity and the phase plane during the bouting phase of rhythmic activity recovery.

Fig. 4

(a) Membrane potential changes over time; arrows point to damped subthreshold oscillations leading to and emerging from the period of bursting. (b) Phase plane showing both the V-nullcline (dV/dt = 0) and mKd-nullcline (dmKd/dt = 0). The system’s trajectory is shown by the thick curve. (c) Phase plane as in (b) but zoomed in on the region around the left-most fixed point at the time of transition from bursting to silence (right handside arrow in (a))
