A method for event-related phase/amplitude coupling [PDF]
NeuroImage, 2012 Phase/amplitude coupling (PAC) is emerging as an important electrophysiological measure of local and long-distance neuronal communication. Current techniques for calculating PAC provide a numerical index that represents an average value across an arbitrarily long time period.

Coupled phase-amplitude dynamics in heterogeneous metacommunities
Journal of Theoretical Biology, 2021 Spatial synchrony of population fluctuations is an important tool for predicting regional stability. Its application to natural systems is still limited by the complexity of ecological time series displaying great variation in the frequency and amplitude of their fluctuations, which are not fully resolved by current ecological theories of spatial ...

Understanding phase-amplitude coupling from bispectral analysis [PDF]
International Journal of Psychophysiology, 2020 AbstractTwo measures of cross-frequency coupling (CFC) are Phase-Amplitude Coupling (PAC) and bicoherence. The estimation of PAC with meaningful bandwidth for the high frequency amplitude is crucial in order to avoid misinterpretations. While recommendations on the bandwidth of PAC’s amplitude component exist, there is no consensus yet.

Frontiers in Neuroscience, 2020 A large variety of methods exist to estimate brain coupling in the frequency domain from electrophysiological data measured, e.g., by EEG and MEG. Those data are to reasonable approximation, though certainly not perfectly, Gaussian distributed. This work

Dissociated neuronal phase- and amplitude-coupling patterns in the human brain
NeuroImage, 2020 Coupling of neuronal oscillations may reflect and facilitate the communication between neuronal populations. Two primary neuronal coupling modes have been described: phase-coupling and amplitude-coupling.

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 ...

Intensity noise reduction in semiconductor lasers by amplitude-phase decorrelation [PDF]
, 1990 Detuned operation of a laser results in coupling of field amplitude and phase fluctuations. In a semiconductor laser, this coupling is known to be very large.
