Fig 8. Spontaneous emergence of assemblies for four different motif combinations.

Considering only motifs related to the cross-covariance C_ij (blue), from all cumulants (C_ij, C_ii and K_ij) without the ‘loop’ terms (red), from the cross-covariance C_ij plus the ‘loop’ terms (yellow) and from all cumulants (purple). A. Averaged connectivity matrices over 100 trials at steady state for four different motif combinations and modulation parameter η₋ = 13. Matrices are reordered using the k-means clustering algorithm (see Methods). B. Mean clustering coefficient versus the modulation parameter η₋. C. Mean global efficiency versus the modulation parameter η₋. D. Mean modularity versus the modulation parameter η₋. All results are calculated from 100 trials at steady state connectivity. Error bars represent the standard error of the mean.
