Thalamocortical control of propofol phase-amplitude coupling. [PDF]
PLoS Computational Biology, 2017 The anesthetic propofol elicits many different spectral properties on the EEG, including alpha oscillations (8-12 Hz), Slow Wave Oscillations (SWO, 0.1-1.5 Hz), and dose-dependent phase-amplitude coupling (PAC) between alpha and SWO. Propofol is known to

Phase-Amplitude Coupling in Spontaneous Mouse Behavior. [PDF]
PLoS ONE, 2016 The level of activity of many animals including humans rises and falls with a period of ~ 24 hours. The intrinsic biological oscillator that gives rise to this circadian oscillation is driven by a molecular feedback loop with an approximately 24 hour ...

Phase-amplitude coupling in neuronal oscillator networks [PDF]
Physical Review Research, 2021 Cross-frequency phase-amplitude coupling (PAC) describes the phenomenon where the power of a high-frequency oscillation evolves with the phase of a low-frequency one. It has been widely observed in the brain and linked to various brain functions. In this

A canonical circuit for generating phase-amplitude coupling. [PDF]
PLoS ONE, 2014 'Phase amplitude coupling' (PAC) in oscillatory neural activity describes a phenomenon whereby the amplitude of higher frequency activity is modulated by the phase of lower frequency activity. Such coupled oscillatory activity--also referred to as 'cross-

A Precise Annotation of Phase-Amplitude Coupling Intensity. [PDF]
PLoS ONE, 2016 Neuronal information can be coded in different temporal and spatial scales. Cross-frequency coupling of neuronal oscillations, especially phase-amplitude coupling (PAC), plays a critical functional role in neuronal communication and large scale neuronal ...

Empirical analysis of phase-amplitude coupling approaches.
PLoS ONE, 2019 Analysis of the coupling between the phases and amplitudes of oscillations within the same continuously sampled signal has provided interesting insights into the physiology of memory and other brain process, and, more recently, the pathophysiology of ...

Phase-amplitude coupling supports phase coding in human ECoG [PDF]
eLife, 2015 Prior studies have shown that high-frequency activity (HFA) is modulated by the phase of low-frequency activity. This phenomenon of phase-amplitude coupling (PAC) is often interpreted as reflecting phase coding of neural representations, although ...

The Bispectrum and Its Relationship to Phase-Amplitude Coupling [PDF]
NeuroImage, 2018 Most biological signals are non-Gaussian, reflecting their origins in highly nonlinear physiological systems. A versatile set of techniques for studying non-Gaussian signals relies on the spectral representations of higher moments, known as polyspectra ...
