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…

Phenomenological renormalization group in neuronal models near criticality

Kaio F. R. Nascimento, Daniel M. Castro, Gustavo G. Cambrainha +1

The phenomenological renormalization group (PRG) has been applied to the study of scaleinvariant phenomena in neuronal data, providing evidence for critical phenomena in the brain.…

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…

Feedforward and feedback influences through distinct frequency bands between two spiking-neuron networks

Leonardo Dalla Porta, Daniel M. Castro, Mauro Copelli +2

Several studies with brain signals suggested that bottom-up and top-down influences are exerted through distinct frequency bands among visual cortical areas. It has been recently s…
