Multifractal human signals at the edge of life reveal a heart-brain anti-correlation
Yago Emanoel Ramos, Maria Eloá do Ó, Henrique Ferraz de Arruda +3
This study investigates the terminal breakdown of human neurophysiological function through the lens of non-linear dynamics by analyzing the multifractal spectrum. Using Multifract…
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…
Revealing stimulus-dependent dynamics through statistical complexity
Edson V. de Paula, Rafael M. Jungmann, Antonio J. Fontenele +5
Advances in large-scale neural recordings have expanded our ability to describe the activity of distributed brain circuits. However, understanding how neural population dynamics di…
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…
State-dependent complexity of the local field potential in the primary visual cortex
Rafael M. Jungmann, Thaís Feliciano, Leandro A. A. Aguiar +7
The local field potential (LFP) is as a measure of the combined activity of neurons within a region of brain tissue. While biophysical modeling schemes for LFP in cortical circuits…
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…
