Hierarchical organization of critical brain dynamics
Gustavo G. Cambrainha, Daniel M. Castro, Leonardo L. Gollo +2
The hierarchical organization of the brain is a fundamental structural principle, while brain criticality is a leading hypothesis for its collective dynamics. However, the connecti…

Interdependent scaling exponents in the human brain
Daniel M. Castro, Ernesto P. Raposo, Mauro Copelli +1
We apply the phenomenological renormalization group to resting-state fMRI time series of brain activity in a large population. By recursively coarse-graining the data, we compute s…

Criticality at work: scaling in the mouse cortex enhances performance
Gustavo G. Cambrainha, Daniel M. Castro, Nivaldo A. P. de Vasconcelos +2
The critical brain hypothesis posits that neural systems operate near a phase transition, optimizing the processing of information. While scale invariance and non-Gaussian dynamics…
