Correlations between synchronization in the shell, normalized distance threshold $\frac{D_{PT}}{D_{PT,max}}$ in the distance-dependent model, probability P _PT in the probability-dependent model, and the average number of links per shell neuron. Orange and blue curves are modeled with distance-dependent and probability-dependent networks, respectively. (A) as probability increases, the average connection rises linearly in the probability-dependent network, while as the distance threshold increases, the average connection rises in a sigmoid fashion. (B) and (C) in the probability-dependent network, the synchronization level increases rapidly as functions of probability and average connections, while this increase is more graduate in the distance-dependent model.
