Autonomous emergence of connectivity assemblies via spike triplet interactions
Fig 8
Spontaneous emergence of assemblies for four different motif combinations.
Considering only motifs related to the cross-covariance Cij (blue), from all cumulants (Cij, Cii and Kij) without the ‘loop’ terms (red), from the cross-covariance Cij 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.
