Figure 6. — Consistent changes in connection patterns observed in fronts 1 through 4 across all three datasets. (a) Density of empirical and evolved networks. (b) New connections (red points) in evolved networks tend to extend over long spatial distances; fibre densities that are weakened during evolution (blue points) tend to involve pairs of nodes that are spatially close or belong to the same anatomical region. (c) High-cost connections are principal targets for rewiring during the evolutionary process.
