Relation between the phase-lag index and lagged coherence for assessing interactions in EEG and MEG data [PDF]

open access: yesNeuroImage: Reports, 2021
Over the last two decades, a large number of estimators have been proposed to assess brain connectivity from electroencephalography (EEG) and magnetoencephalography (MEG) data.

Reproducibility of functional connectivity and graph measures based on the phase lag index (PLI) and weighted phase lag index (wPLI) derived from high resolution EEG. [PDF]

open access: yesPLoS ONE, 2014
Functional connectivity (FC) and graph measures provide powerful means to analyze complex networks. The current study determines the inter-subject-variability using the coefficient of variation (CoV) and long-term test-retest-reliability (TRT) using the ...

Phase Lag Index of Resting-State EEG for Identification of Mild Cognitive Impairment Patients with Type 2 Diabetes [PDF]

open access: yesBrain Sciences, 2022
Mild cognitive impairment (MCI) is one of the important comorbidities of type 2 diabetes mellitus (T2DM). It is critical to find appropriate methods for early diagnosis and objective assessment of mild cognitive impairment patients with type 2 diabetes ...

Mental workload evaluation using weighted phase lag index and coherence features extracted from EEG data [PDF]

open access: yesBrain Research Bulletin
Electroencephalogram (EEG) represents an effective, non-invasive technology to study mental workload. However, volume conduction, a common EEG artifact, influences functional connectivity analysis of EEG data. EEG coherence has been used traditionally to

EEG Resting State Functional Connectivity in Adult Dyslexics Using Phase Lag Index and Graph Analysis [PDF]

open access: yesFrontiers in Human Neuroscience, 2018
Developmental dyslexia may involve deficits in functional connectivity across widespread brain networks that enable fluent reading. We investigated the large-scale organization of electroencephalography (EEG) functional networks at rest in 28 dyslexics ...

Weighted phase lag index stability as an artifact resistant measure to detect cognitive EEG activity during locomotion [PDF]

open access: yesJournal of NeuroEngineering and Rehabilitation, 2012
Background High-density electroencephalography (EEG) with active electrodes allows for monitoring of electrocortical dynamics during human walking but movement artifacts have the potential to dominate the signal.

The level of cognitive functioning in school-aged children is predicted by resting EEG Directed Phase Lag Index [PDF]

open access: yesScientific Reports
Quantifying cognitive potential relies on psychometric measures that do not directly reflect cortical activity. While the relationship between cognitive ability and resting state EEG signal dynamics has been extensively studied in children with below ...

Brain functional connectivity based on phase lag index of electroencephalography for automated diagnosis of schizophrenia using residual neural networks. [PDF]

open access: yesJ Appl Clin Med Phys, 2023
AbstractThe complexity of symptoms of schizophrenia (SZ) complicate traditional and effective diagnoses based on clinical signs. Moreover, clinical diagnosis of SZ is manual, time‐consuming, and error‐prone. Thus, there is a requirement to develop automated systems for timely and accurate diagnosis of SZ.

The influence of neuromuscular blockade on phase lag entropy and bispectral index: A randomized, controlled trial.

open access: yesPLoS ONE, 2021
The aim of this study is to compare the effects of neuromuscular blockade (NMB) on phase lag entropy (PLE) and the bispectral index (BIS). We recorded the BIS, electromyograph (EMG) activity on a BIS monitor (EMG_BIS), PLE, and EMG activity on a PLE ...
