Cross-Frequency Coupling and Intelligent Neuromodulation. [PDF]

Cyborg Bionic Syst, 2023
Cross-frequency coupling (CFC) reflects (nonlinear) interactions between signals of different frequencies. Evidence from both patient and healthy participant studies suggests that CFC plays an essential role in neuronal computation, interregional interaction, and disease pathophysiology.

Cross-Frequency Coupling in Developmental Perspective. [PDF]

Front Hum Neurosci, 2019
It is generally assumed that different electroencephalogram (EEG) frequency bands are somehow related to different computational modes in the brain. Integration of these computational modes is reflected in the phenomenon of cross-frequency coupling (CFC).

Neural Cross-Frequency Coupling Functions [PDF]

Frontiers in Systems Neuroscience, 2017
Although neural interactions are usually characterized only by their coupling strength and directionality, there is often a need to go beyond this by establishing the functional mechanisms of the interaction. We introduce the use of dynamical Bayesian inference for estimation of the coupling functions of neural oscillations in the presence of noise. By

Theta-gamma coupling: nonlinearity as a universal cross-frequency coupling mechanism. [PDF]

Front Behav Neurosci
The Cross Frequency Coupling (CFC) phenomenon is defined as a statistical correlation between characteristic parameters neural oscillations. This study demonstrates and analyzes the nonlinear mechanism of the CFC, with a focus on the coupling between slow and fast oscillations, as a model for theta-gamma coupling.

A neural mass model of cross frequency coupling [PDF]

PLOS ONE, 2017
Electrophysiological signals of cortical activity show a range of possible frequency and amplitude modulations, both within and across regions, collectively known as cross-frequency coupling. To investigate whether these modulations could be considered as manifestations of the same underlying mechanism, we developed a neural mass model.

Working Memory and Cross-Frequency Coupling of Neuronal Oscillations. [PDF]

Front Psychol, 2021
Working memory (WM) is the active retention and processing of information over a few seconds and is considered an essential component of cognitive function. The reduced WM capacity is a common feature in many diseases, such as schizophrenia, attention deficit hyperactivity disorder (ADHD), mild cognitive impairment (MCI), and Alzheimer's disease (AD ...

Abnormal cross-frequency coupling in the tinnitus network [PDF]

Frontiers in Neuroscience, 2014
Neuroimaging studies have identified networks of brain areas and oscillations associated with tinnitus perception. However, how these regions relate to perceptual characteristics of tinnitus, and how oscillations in various frequency bands are associated with communications within the tinnitus network is still incompletely understood.

Multivariate cross-frequency coupling via generalized eigendecomposition [PDF]

eLife, 2017
Abstract This paper presents a new framework for analyzing cross-frequency coupling in multichannel electrophysiological recordings. The generalized eigendecomposition-based cross-frequency coupling framework (gedCFC) is inspired by source separation algorithms combined with dynamics of mesoscopic neurophysiological processes.

What can neurofeedback and transcranial alternating current stimulation reveal about cross-frequency coupling? [PDF]

Frontiers in Neuroscience
In recent years, the dynamics and function of cross-frequency coupling (CFC) in electroencephalography (EEG) have emerged as a prevalent area of investigation within the research community. One possible approach in studying CFC is to utilize non-invasive

Cross-frequency coupling in real and virtual brain networks [PDF]

Frontiers in Computational Neuroscience, 2013
Information processing in the brain is thought to rely on the convergence and divergence of oscillatory behaviors of widely distributed brain areas. This information flow is captured in its simplest form via the concepts of synchronization and desynchronization and related metrics.
