Figure 5.

(a) Phase diagram in the plane (K, d) in the limit $\Lambda \gg 1$ containing three regions: unstable spirals (with an inset representing steady oscillations), stable spirals (with an inset representing damped oscillations) and stable node (with an inset representing a curve with no oscillations); and (b) evolution of the fixed point coordinates ($x^{*}$, ${\lambda }^{*}$) as a function of K, on the Hopf bifurcation (solid line) and on the transition line between the stable node and stable spirals (dashed line).
