Untangling cross-frequency coupling in neuroscience [PDF]

Current Opinion in Neurobiology, 2014
Abstract Cross-frequency coupling (CFC) has been proposed to coordinate neural dynamics across spatial and temporal scales. Despite its potential relevance for understanding healthy and pathological brain function, the standard CFC analysis and physiological interpretation come with fundamental problems.

The functional role of cross-frequency coupling [PDF]

Trends in Cognitive Sciences, 2010
Recent studies suggest that cross-frequency coupling (CFC) might play a functional role in neuronal computation, communication and learning. In particular, the strength of phase-amplitude CFC differs across brain areas in a task-relevant manner, changes quickly in response to sensory, motor and cognitive events, and correlates with performance in ...

Dissociating harmonic and non-harmonic phase-amplitude coupling in the human brain

NeuroImage, 2021
Phase-amplitude coupling (PAC) has been hypothesized to coordinate cross-frequency interactions of neuronal activity in the brain. However, little is known about the distribution of PAC across the human brain and the frequencies involved. Furthermore, it

Cross-Frequency Coupling in Descending Motor Pathways: Theory and Simulation. [PDF]

Front Syst Neurosci, 2019
Coupling of neural oscillations is essential for the transmission of cortical motor commands to motoneuron pools through direct and indirect descending motor pathways. Most studies focus on iso-frequency coupling between brain and muscle activities, i.e.,

Communication through coherence by means of cross-frequency coupling [PDF]

Neuroscience, 2020
The theory of communication through coherence (CTC) posits the synchronization of brain oscillations as a key mechanism for information sharing and perceptual binding. In a parallel literature, hippocampal theta activity (4 – 10 Hz) has been shown to modulate the appearance of neocortical fast gamma oscillations (100 – 150 Hz), a phenomenon known as ...

Cross-Frequency Coupling as a Biomarker for Early Stroke Recovery. [PDF]

Neurorehabil Neural Repair
Background The application of neuroimaging-based biomarkers in stroke has enriched our understanding of post-stroke recovery mechanisms, including alterations in functional connectivity based on synchronous oscillatory activity across various cortical regions.

Age-dependent cross frequency coupling features from children to adults during general anesthesia

NeuroImage, 2021
Background: The frequency coupling characteristics in electroencephalogram (EEG) induced by anesthetics have been well studied in adults, but the investigation of the age-dependent cross frequency coupling features from children to adults is still ...

Parametric estimation of cross-frequency coupling

Journal of Neuroscience Methods, 2015
Growing experimental evidence suggests an important role for cross-frequency coupling in neural processing, in particular for phase-amplitude coupling (PAC). Although the details of methods to detect PAC may vary, a common procedure to estimate the significance level is the comparison of observed values to those of at least 100 surrogate time series ...
