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…
Unconventional criticality, scaling breakdown, and diverse universality classes in the Wilson-Cowan model of neural dynamics
Helena Christina Piuvezam, Bóris Marin, Mauro Copelli +1
The Wilson-Cowan model constitutes a paradigmatic approach to understanding the collective dynamics of networks of excitatory and inhibitory units. It has been profusely used in th…
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…
Mechanisms of self-organized quasicriticality in neuronal networks models
Osame Kinouchi, Renata Pazzini, Mauro Copelli
The critical brain hypothesis states that there are information processing advantages for neuronal networks working close to the critical region of a phase transition. If this is t…
Statistical complexity is maximized close to criticality in cortical dynamics
Nastaran Lotfi, Thaís Feliciano, Leandro A. A. Aguiar +6
Complex systems are typically characterized as an intermediate situation between a complete regular structure and a random system. Brain signals can be studied as a striking exampl…
Anticipated synchronization in human EEG data: unidirectional causality with negative phase-lag
Francisco-Leandro P. Carlos, Maciel-Monteiro Ubirakitan, Marcelo Cairrão Araújo Rodrigues +6
Understanding the functional connectivity of the brain has become a major goal of neuroscience. In many situatons, the relative phase difference, together with coherence patterns,…
