Phase and amplitude analysis in time-frequency space--application to voluntary finger movement.
TLDR
The earlier known phenomena, connected with voluntary movements, were confirmed and a new evidence concerning focal ERD/surround ERS and beta activity post-movement synchronization was found.About:

Identifying true brain interaction from EEG data using the imaginary part of coherency.
TL;DR: It is possible to reliably detect brain interaction during movement from EEG data and it is argued that the Cartesian representation is far superior for studying brain interactions.
Journal ArticleDOI
Nonlinear multivariate analysis of neurophysiological signals
TL;DR: This work describes the multivariate linear methods most commonly used in neurophysiology and shows that they can be extended to assess the existence of nonlinear interdependence between signals and describes nonlinear methods based on the concepts of phase synchronization, generalized synchronization and event synchronization.
Journal ArticleDOI
The use of time-variant EEG Granger causality for inspecting directed interdependencies of neural assemblies.
TL;DR: Simulations demonstrate the usefulness of the time-variant Granger causality for detecting dynamic causal relations within time intervals of less than 100 ms.
Journal ArticleDOI
Determination of EEG activity propagation: pair-wise versus multichannel estimate
TL;DR: The results show unequivocally that in most cases, the pair-wise estimates are incorrect and a complete set of signals involved in a given process has to be used to obtain the correct pattern of EEG flows.
Journal ArticleDOI
Review of the methods of determination of directed connectivity from multichannel data.
TL;DR: The methods applied for estimation of functional connectivity from multichannel data are described with special emphasis on the estimators of directedness such as directed transfer function (DTF) and partial directed coherence based on multivariate autoregressive model.

A new look at the statistical model identification
TL;DR: In this article, a new estimate minimum information theoretical criterion estimate (MAICE) is introduced for the purpose of statistical identification, which is free from the ambiguities inherent in the application of conventional hypothesis testing procedure.
Journal ArticleDOI
Investigating Causal Relations by Econometric Models and Cross-Spectral Methods
TL;DR: In this article, the cross spectrum between two variables can be decomposed into two parts, each relating to a single causal arm of a feedback situation, and measures of causal lag and causal strength can then be constructed.

Bootstrap Methods: Another Look at the Jackknife
TL;DR: In this article, the authors discuss the problem of estimating the sampling distribution of a pre-specified random variable R(X, F) on the basis of the observed data x.

Matching pursuits with time-frequency dictionaries
Stéphane Mallat,Zhifeng Zhang +1 more
TL;DR: The authors introduce an algorithm, called matching pursuit, that decomposes any signal into a linear expansion of waveforms that are selected from a redundant dictionary of functions, chosen in order to best match the signal structures.
Book
Digital spectral analysis : with applications
TL;DR: This new book provides a broad perspective of spectral estimation techniques and their implementation concerned with spectral estimation of discretespace sequences derived by sampling continuousspace signals.
