We review feasible, pairwise, and multivariate implementations of various non-directed and directed coupling techniques, and provide an overview of the applications in EEG brain connectivity. We highlight some of the technical challenges and introduce some of the other commonly utilized connectivity estimators and emerging trends in this field.
Electroencephalographic Connectivity: A Fundamental Guide and …
Jun 1, 2022 · EEG connectivity involves the identification of statistically significant synchronization between the signals obtained from two or more EEG electrodes (3, 4). Several techniques can be used to perform EEG connectivity analyses.
Electrophysiological Brain Connectivity: Theory and Implementation
Intracranial EEG (iEEG), EEG/MEG, and the source signals reconstructed by EEG/MEG source imaging techniques have been proven efficient for measuring brain functional connectivity between various regions.

Obtained results of EEG–EMG coherence allow determine how functional corticomuscular connectivity occurs between brain cortical area and specific muscles when a reach-grasp-lift-hold and replace an object motor task was performed.
Connectivity Analysis in EEG Data: A Tutorial Review of the
In this work, we provide a technical account and a categorization of the most-used data-driven approaches to assess brain-functional connectivity, intended as the study of the statistical dependencies between the recorded EEG signals.
Electroencephalographic Connectivity: A Fundamental Guide and …
We discuss how factors such as referencing, epoch length and number, controls for volume conduction, artifact removal, and statistical control of multiple comparisons influence the EEG connectivity estimate for connectivity measures, and what can be done to control for potential confounds associated with these factors.
EEG-CONNECTIVITY: A FUNDAMENTAL GUIDE AND CHECKLIST 3 Highlights • Research findings, background information, and recommendations from the existing EEG literature are summarised and compiled to propose a novel checklist to evaluate EEG connectivity analyses.
EEG and MEG coherence: measures of functional connectivity …
With the new ellipsoidal model and realistic source geometry, we quantify the spatial resolutions of conventional EEG, Laplacian, and MEG and estimate the effects of volume conduction (EEG, Laplacian) and separation of sources from sensors (EEG, …
