Fig 9. Spontaneous emergence of assemblies due to the modulation of synaptic transmission.
A. Varying the time constant τι changes the shape of the EPSC function, shifting its peak by a few milliseconds. B. Relative value of the motif coefficients as a function of τι. While the common input motif M1,1 rapidly assumes dominance, the motif coefficient M1,2 crosses over in strength with the feedback motifs M0,1, M0,2 and M0,3. C. Averaged connectivity matrices over 100 trials at steady state and different values of the time constant τι. Matrices are reordered using the k-means clustering algorithm (see Methods). D. Mean clustering coefficient versus the time constant τι. E. Mean global efficiency versus the time constant τι. F. Mean modularity versus the the time constant τι. All results are calculated from 100 trials at steady state connectivity. Error bars represent the standard error of the mean.
