The article explores how synchronization can occur in complex networks, like the human brain, beyond simple star graphs. By creating a model of multi-layered community networks, the researchers found that synchronization can happen when the central community is strongly connected compared to the outer communities. They also discovered that factors like frequency distributions and network size play a role in this synchronization. These findings were supported by analyzing real brain networks. Overall, the study shows how synchronization can occur in multi-layered community networks with star-like topologies.
