Phys Rev Res. 2022;4(2):023057. DOI: 10.1103/PhysRevResearch.4.0230572643-1564http://hdl.handle.net/10230/55977Previous simulation studies on human connectomes suggested that critical dynamics emerge subcritically in the so-called Griffiths phases. Now we investigate this on the largest available brain network, the 21662 node fruit-fly connectome, using the Kuramoto synchronization model. As this graph is less heterogeneous, lacking modular structure and exhibiting high topological dimension, we expect a difference from the previous results. Indeed, the synchronization transition is mean-field-like, and the width of the transition region is larger than in random graphs, but much smaller than as for the KKI-18 human connectome. This demonstrates the effect of modular structure and dimension on the dynamics, providing a basis for better understanding the complex critical dynamics of humans.application/pdfengPublished by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
