Understanding how different areas of the human brain communicate with each other is a
crucial issue in neuroscience. The concepts of structural, functional and effective …

This review considers state-of-the-art analyses of functional integration in neuronal
macrocircuits. We focus on detecting and estimating directed connectivity in neuronal …

Abstract Background Wiener–Granger causality (“G-causality”) is a statistical notion of
causality applicable to time series data, whereby cause precedes, and helps predict, effect. It …

One challenging aspect of the clinical assessment of brain-injured, unresponsive patients is
the lack of an objective measure of consciousness that is independent of the subject's ability …

In recent years, numerous electrophysiological signatures of consciousness have been
proposed. Here, we perform a systematic analysis of these electroencephalography markers …

Granger causality methods were developed to analyze the flow of information between time
series. These methods have become more widely applied in neuroscience. Frequency …

Over the last years, a surge of empirical studies converged on complexity-related measures
as reliable markers of consciousness across many different conditions, such as sleep …

Introduction Directional connectivity from anterior to posterior brain regions (or “feedback”
connectivity) has been shown to be inhibited by the gamma-aminobutyric acid agonists …

Emerging neural theories of consciousness suggest a correlation between a specific type of
neural dynamical complexity and the level of consciousness: When awake and aware …

This joint article reflects the authors' personal views regarding noteworthy advances in the
neuroscience of consciousness in the last 10 years, and suggests what we feel may be …
