Fig. 12From: Measuring Edge Importance: A Quantitative Analysis of the Stochastic Shielding Approximation for Random Processes on GraphsIllustration of the Hodgkin–Huxley sodium channel. This channel has eight states, where state 8 is the conducting state, and 20 reactions. The reactions are labeled in blue and are used to define the edge importance values R k in the figures below. The reaction rates α m , α h , β m , and β h are voltage-dependent, defined in Eqs. 51–52Back to article page
