Hodgkin–Huxley potassium channel: variance of current and state occupancy. Left: variance of the current $R_k\ast {(V-V_k)}^2$ as a function of voltage V for each reaction k where $V_k=-77\text{ mV}$ is the reversal potential for the potassium channel. The blue curve$R_7=R_8$ has the highest variance. Right: leading eigenvector components (normalized so that the components sum to 1) as a function of voltage
