Gating variable steady-state and time-scale functions. a The four gating variable steady-state functions, $m_{\mathrm{\infty }}(V)$ (red), $h_{\mathrm{\infty }}(V)$ (orange), $n_{\mathrm{\infty }}(V)$ (green), and $w_{\mathrm{\infty }}(V)$ (blue). These functions give the opening probability of their respective ion channels for a given value of the membrane voltage, V. b The four gating variable time-scale functions, ${\tau }_m(V)$ (red), ${\tau }_h(V)$ (orange), ${\tau }_n(V)$ (green), and ${\tau }_w(V)$ (blue). These functions describe the rough time-scales on which each gating variable evolves for a given value of the membrane voltage. c A closer look at panel b reveals that ${\tau }_m(V)$, ${\tau }_h(V)$ and ${\tau }_n(V)$ evolve on much smaller time-scales than ${\tau }_w(V)$
