Interplay between Graph Topology and Correlations of Third Order in Spiking Neuronal Networks

Pictorial representation of terms contributing to κijk(t1, t2, t3).
Each κijk(t1, t2, t3) is a weighted sum of integral terms, corresponding to rooted trees with leaves i, j and k (see Eq 21). The first term maps to the left tree, while the three remaining terms correspond to three possible ways in which three labeled leaves can be arranged into two groups to form the tree on the right. The first group would represent the daughter nodes of vertex m, and the second group would be a single child of the root node n.
