An example of fold/fold cycle bursting in the WCI model (Equations 9a-9c) at $(k,r_x)=(0.6,-4.76)$. (a) Time series of the fast V variable. (b) The bursting trajectory (blue curve) is plotted in projection onto the $(u,x)$ phase space, along with the bifurcation diagram of the fast system at this value of $r_x$. Plotting conventions follow Figure 2.
