Dependence of firing rate (a) and corresponding ISIs (b) on the ionic conductance $g_{\mathit{AHP}}$ when $g_M=0.1{\mathrm{mS}/\mathrm{cm}}^2$ and $g_K=10.0{\mathrm{mS}/\mathrm{cm}}^2$. c Some typical membrane potential of this neuron model for different $g_{\mathit{AHP}}$: c1$g_{\mathit{AHP}}=0.2{\mathrm{mS}/\mathrm{cm}}^2$, c2$g_{\mathit{AHP}}=0.31{\mathrm{mS}/\mathrm{cm}}^2$, c3$g_{\mathit{AHP}}=0.32{\mathrm{mS}/\mathrm{cm}}^2$, c4$g_{\mathit{AHP}}=0.5{\mathrm{mS}/\mathrm{cm}}^2$. It can be seen that with the increase of $g_{\mathit{AHP}}$, the firing rate of the present neuron decreases and the corresponding ISIs first increase and then decreases
