Two parameter bifurcations in the plane (I _app, g _exc) of the ML model with an excitatory autapse. SubH is subcritical Hopf curve. BHom and SHom are saddle homoclinic orbit bifurcation curves. ${\mathrm{SN}}_{\mathrm{1}}^{\mathrm{S}}$, ${\mathrm{SN}}_{\mathrm{1}}^{\mathrm{U}}$, ${\mathrm{SN}}_{\mathrm{2}}^{\mathrm{S}}$ and ${\mathrm{SN}}_{\mathrm{2}}^{\mathrm{U}}$ are curves of saddle node bifurcation of equilibrium. LPC represents the curve of saddle node bifurcation of limit cycle. CP is cusp bifurcation. BT is Bogdanov-Takens bifurcation.
