Some typical phase orbits in V–n phase plane for different $g_{\mathit{AHP}}$: a$g_{\mathit{AHP}}=0.0{\mathrm{mS}/\mathrm{cm}}^2$, b$g_{\mathit{AHP}}=0.2{\mathrm{mS}/\mathrm{cm}}^2$, c$g_{\mathit{AHP}}=0.317{\mathrm{mS}/\mathrm{cm}}^2$, d$g_{\mathit{AHP}}=0.318{\mathrm{mS}/\mathrm{cm}}^2$, e$g_{\mathit{AHP}}=0.35{\mathrm{mS}/\mathrm{cm}}^2$, f$g_{\mathit{AHP}}=0.5{\mathrm{mS}/\mathrm{cm}}^2$. Note that the subplot representing the stable phase orbit after discarding transient state. The state of this pyramidal neuron changes from the limit cycle to the equilibrium point with the increase of $g_{\mathit{AHP}}$
