This approach was applied into two systems: a directed-coupled Rossler-Lorenz system and a network of Izhikevich neurons. For the former case, the phase-lag synchronization revealed an increase in complexity for the Lorenz subsystem components, when the coupling is activated. The opposite behavior was observed when the Izhikevich network were organized in a hierarchical way. Our results point out to emergent synchronism related to causal interactions in coupled complex systems.41-49engArtigo10.1140/epjst/e2016-02618-7WOS:000371423700005Acesso abertoWOS000371423700005.pdf
