The purpose of the present paper is to develop a method, based on equal-time correlation, correlation matrix analysis and surrogate resampling, that is able to quantify and describe properties of synchronization of population neuronal activity recorded simultaneously from multiple sites. Initially, Lorenz-type oscillators were used to model multiple time series with different patterns of synchronization. Eigenvalue and eigenvector decomposition was then applied to identify "clusters" of locally…

Neural Mass Modeling for Multi-Channel EEG Synchronization Analyzing
TLDR
A multi-channel neural mass model (NMM) is developed and used to generate multiple EEG signals, then a coherence and correlation matrix analysis method was used to analyze the dynamic and synchronous characteristic of the new model.
Multivariate EEG Synchronization Strength Measures
TLDR
In this chapter, the multivariate synchronization methods including phase synchronization cluster analysis, S-estimator, correlation matrix analysis, omega complexity, partial directed coherence, directed transfer function, and complex network analysis and their applications in studying the relationship among neural signals are presented.
The Comodulation Measure of Neuronal Oscillations
TLDR
In this chapter, a phase randomisation-based wavelet bicoherence method was introduced, which allows us to reliably measure the comodulation of neuronal oscillations between different frequency bands and investigate the cross-frequency interaction in physiological signals.
The Application of Phase Synchronization in Continuous Neural Signals
TLDR
The method of phase-based synchronization was used to calculate the phase lock value (PLV) of the local field potential (LFP) signal between the prefrontal cortex (PFC) and striatum (STR) in the monkey and it was found that the phase synchronism in the beta frequency band was clearly different for different test conditions and different test stages.

TLDR
Results show a significant difference on GFS value between selected data sets, where for the unhealthy part shows a lower value of GFS than the healthy part.

Global Synchronization Measurement of Multivariate Neural Signals with Massively Parallel Nonlinear Interdependence Analysis
TLDR
The proposed G-NLI method can support real-time global synchronization measurement and it could be successful in localization of epileptic focus and it has improved the runtime performance by more than 1000 times comparing to the original sequential NLI.
Visualizing Dynamical Neural Assemblies with a Fuzzy Synchronization Clustering Analysis
TLDR
A method of fuzzy synchronization clustering analysis (FSCA) is proposed to avoid the constraint of orthogonality by combining the fuzzy c-means algorithm with the phase-locking value and produced consistent findings for the qualitatively salient configuration of the original network.
Assessment of Multivariate Neural Time Series by Phase Synchrony Clustering in a Time-Frequency-Topography Representation
TLDR
A framework for characterization of phase synchrony relationships between multivariate neural time series is presented, relying on a proposed clustering algorithm, termed Multivariate Time Series Clustering by Phase Synchrony, which generates fuzzy clusters for each multivalued time sample and thereupon obtains hard clusters according to a circular variance threshold.

Eigenvalue Decomposition as a Generalized Synchronization Cluster Analysis
TLDR
It is shown that eigenvalue decomposition can also be applied to a matrix of indices of bivariate phase synchronization strength and is able to identify clusters of synchronized oscillators, and to quantify their strength as well as the degree of involvement of an oscillator in a cluster.
