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…
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…
