The effect of the excitatory feedback in anticipated synchronization and phase bistability regimes in neuronal populations
Julio N. Machado, Joana M. G. L. Silva, Katiele V. Brito +2
Anticipated synchronization (AS), in which the receiver leads the sender and the phase lag is negative, can emerge in unidirectionally coupled dynamical systems when the receiver h…
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…
The role of inhibitory neuronal variability in modulating phase diversity between coupled networks
Katiele V. P. Brito, Joana M. G. L. Silva, Claudio R. Mirasso +1
Neuronal heterogeneity, characterized by the presence of a multitude of spiking neuronal patterns, is a widespread phenomenon throughout the nervous system. In particular, the brai…
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…
Neuronal heterogeneity modulates phase-synchronization between unidirectionally coupled populations with excitation-inhibition balance
Katiele V. P. Brito, Fernanda Selingardi Matias
Several experiments and models have highlighted the importance of neuronal heterogeneity in brain dynamics and function. However, how such a cell-to-cell diversity can affect corti…
A symbolic information approach to characterize response-related differences in cortical activity during a Go/No-Go task
Helena B. Lucas, Steven L. Bressler, Fernanda S. Matias +1
How the brain processes information from external stimuli in order to perceive the world and act on it is one of the greatest questions in neuroscience. To address this question di…
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…
Phase-bistability between anticipated and delayed synchronization in neuronal populations
Julio Nunes Machado, Fernanda Selingardi Matias
Two dynamical systems unidirectionally coupled in a sender-receiver configuration can synchronize with a nonzero phase-lag. In particular, the system can exhibit anticipated synchr…
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,…
Topology of many-body edge and extended quantum states in an open spin chain: 1/3--plateau, Kosterlitz-Thouless transition, and Luttinger liquid
R. R. Montenegro-Filho, F. S. Matias, M. D. Coutinho-Filho
Quantum many-body edge and extended magnon excitations from the 1/3 -- plateau of the anisotropic Heisenberg model on an open AB chain in a magnetic field are unveiled usin…
Inhibitory autapse mediates anticipated synchronization between coupled neurons
Marcel A. Pinto, Osvaldo A. Rosso, Fernanda S. Matias
Two identical autonomous dynamical systems unidirectionally coupled in a sender-receiver configuration can exhibit anticipated synchronization (AS) if the Receiver neuron (R) also…
Self-sustained activity of low firing rate in balanced networks
Fernando Borges, Paulo Protachevicz, Rodrigo Pena +10
Self-sustained activity in the brain is observed in the absence of external stimuli and contributes to signal propagation, neural coding, and dynamic stability. It also plays an im…
Inferring correlations associated to causal interactions in brain signals using autoregressive models
Víctor J. López-Madrona, Fernanda Matias, Claudio Mirasso +2
The specific connectivity of a neuronal network is reflected in the dynamics of the signals recorded on its nodes. The analysis of how the activity in one node predicts the behavio…
Anticipated synchronization in neuronal circuits unveiled by a phase-resetting curve analysis
Fernanda S. Matias, Pedro V. Carelli, Claudio R. Mirasso +1
Anticipated synchronization (AS) is a counter intuitive behavior that has been observed in several systems. When AS establishes in a sender-receiver configuration, the latter can p…
