Quantifying phase–amplitude coupling in neuronal network oscillations [PDF]
Progress in Biophysics and Molecular Biology, 2011 Neuroscience time series data from a range of techniques and species reveal complex, non-linear interactions between different frequencies of neuronal network oscillations within and across brain regions. Here, we briefly review the evidence that these nested, cross-frequency interactions act in concert with linearly covariant (within-frequency ...

Perspective: Phase Amplitude Coupling–Based Phase–Dependent Neuromodulation in Parkinson’s Disease
Frontiers in Neuroscience, 2020 Deep brain stimulation (DBS) is an effective surgical therapy for Parkinson’s disease (PD). However, limitations of the DBS systems have led to great interest in adaptive neuromodulation systems that can dynamically adjust stimulation parameters to meet ...

Phase–Amplitude Coupling in Human Electrocorticography Is Spatially Distributed and Phase Diverse [PDF]
The Journal of Neuroscience, 2012 Spatially distributed phase-amplitude coupling (PAC) is a possible mechanism for selectively routing information through neuronal networks. If so, two key properties determine its selectivity and flexibility, phase diversity over space, and frequency diversity.

Misidentifications of specific forms of cross-frequency coupling: three warnings
Frontiers in Neuroscience, 2015 Cross-frequency coupling between neural oscillations has received increased attention over the last decade, as it is believed to underlie a number of cognitive operations in different brain systems.

Amplitude and phase dynamics in oscillators with distributed-delay coupling [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013 This paper studies the effects of distributed-delay coupling on the dynamics in a system of non-identical coupled Stuart–Landau oscillators. For uniform and gamma delay distribution kernels, the conditions for amplitude death are obtained in terms of average frequency, frequency detuning and the parameters of the coupling, including coupling strength ...

REPAC: Reliable Estimation of Phase-Amplitude Coupling in Brain Networks [PDF]
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021 Recent evidence has revealed cross-frequency coupling and, particularly, phase-amplitude coupling (PAC) as an important strategy for the brain to accomplish a variety of high-level cognitive and sensory functions. However, decoding PAC is still challenging. This contribution presents REPAC, a reliable and robust algorithm for modeling and detecting PAC

Elevated phase amplitude coupling as a depression biomarker in epilepsy. [PDF]
Epilepsy BehavDepression is prevalent in epilepsy patients and their intracranial brain activity recordings can be used to determine the types of brain activity that are associated with comorbid depression. We performed case-control comparison of spectral power and phase amplitude coupling (PAC) in 34 invasively monitored drug resistant epilepsy patients' brain ...
