Fig. 9From: Measuring Edge Importance: A Quantitative Analysis of the Stochastic Shielding Approximation for Random Processes on GraphsIllustration of the Hodgkin–Huxley potassium channel state graph. This is a 5-state chain where state 5 is the conducting state. The eight reactions are labeled in blue and are used to define the edge importance values R k in the figures below. The reaction rates α n and β n are voltage-dependent as defined by Eqs. 47–48Back to article page
