Trophic structure predicts seizure propagation in brain network models
Peter Kissack, Catherine Drysdale, Samuel Johnson
Epilepsy is widely regarded as a disorder driven by connectivity in the brain. We use a model of seizure dynamics on directed networks to investigate how structural properties affe…
The connection between non-normality and trophic coherence in directed graphs
Catherine Drysdale, Samuel Johnson
Trophic coherence and non-normality are both ways of describing the overall directionality of directed graphs, or networks. Trophic coherence can be regarded as a measure of how ne…
Fitness-Based Growth of Directed Networks with Hierarchy
Niall Rodgers, Peter Tino, Samuel Johnson
Growing attention has been brought to the fact that many real directed networks exhibit hierarchy and directionality as measured through techniques like Trophic Analysis and non-no…
Modeling the extracellular matrix in cell migration and morphogenesis: A guide for the curious biologist
Rebecca M. Crossley, Samuel Johnson, Erika Tsingos +8
The extracellular matrix (ECM) is a highly complex structure through which biochemical and mechanical signals are transmitted. In processes of cell migration, the ECM also acts as…
Functional Optimization in Complex Excitable Networks
Samuel Johnson, J. Marro, Joaquin J. Torres
We study the effect of varying wiring in excitable random networks in which connection weights change with activity to mold local resistance or facilitation due to fatigue. Dynamic…
