Critical brain hypothesis states that neuronal networks in the brain operate close to criticality. This study demonstrates the importance of the hierarchical and modular structure of neuron connections in maintaining criticality: modules with sparsely connected neurons can sustain critical activity even when subjected to significant perturbations; however, as connection density increases, modularity alone proves inadequate to preserve criticality.
