Controlling extended criticality via modular connectivity

arXiv Preprint Archive April 16, 2021 Nikita Gutjahr, Philipp Hövel, Aline Viol preprint

Criticality has been conjectured as an integral part of neuronal network dynamics. Operating at a critical threshold requires precise parameter tuning and a corresponding mechanism remains an open question. Recent studies have suggested that topological features observed in brain networks give rise to a Griffiths phase, leading to power-laws in brain activity dynamics and the operational...
