Model results illustrate that β is a measure of clustering and that electrotonic coupling determines the value of β. The different values for β in A andB reflect model differences (A, binary;B, nonbinary). A, Clustering property dependence on the value of the MRF parameter β. Each square takes a binary value of 0 (white square) or 1 (black square). (1), Randomly distributed configuration with no clusters; corresponding β₁∼ 0. (2), Small clusters, β₂ = 2. (3), Big clusters, β₃ = 3.5 > β₂ > 0. B, Clustering in the modeled network as function couplingd^lm_jk degree.(1), In the presence of reduced coupling (inhibition) in the system, β = 1.0. (2), With increased coupling (absence of inhibition), β = 1.5. Values of β differ forA and B because they relate to different models addressing two different issues. A addresses general model properties and B addresses specific IO modeling (for further explanation, see Materials and Methods).
