Phase-Amplitude Coupling of the Electroencephalogram in the Auditory Cortex in Schizophrenia
Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2018Cross-frequency interactions may coordinate neural circuits operating at different frequencies. While neural oscillations associated with particular circuits in schizophrenia (SZ) are impaired, few studies have examined cross-frequency interactions. Here we examined phase-amplitude coupling (PAC) in the electroencephalograms of individuals with SZ and ...

Matching Pursuit Based Dynamic Phase-Amplitude Coupling Measure
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020Long-distance neuronal communication in the brain is enabled by the interactions across various oscillatory frequencies. One interaction that is gaining importance during cognitive brain functions is phase amplitude coupling (PAC), where the phase of a slow oscillation modulates the amplitude of a fast oscillation.

Granger Causality Based Directional Phase-Amplitude Coupling Measure
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021Phase-amplitude coupling (PAC), which quantifies the coupling between the amplitude of a fast oscillation and the phase of a slow oscillation, is reported as a possible mechanism that controls the flow of information in the brain. Although there is ample evidence suggesting that neural interactions are directional, conventional PAC measures mostly ...

Bilateral preictal signature of phase-amplitude coupling in canine epilepsy
Epilepsy Research, 2018Seizure forecasting would improve the quality of life of patients with refractory epilepsy. Although early findings were optimistic, no single feature has been found capable of individually characterizing brain dynamics during transition to seizure. Cross-frequency phase amplitude coupling has been recently proposed as a precursor of seizure activity ...

Phase amplitude coupling in spectral phase modulation
IEEE Journal of Selected Topics in Quantum Electronics, 1998We report the experimental study of spatio-temporal coupling in spectral phase modulation. Spectral phase modulation relies on the creation of a Fourier plane where spectral components are dispersed and independently focused on a modulator, which allows to locally change the optical path.

A Dynamic Mutual Information Measure of Phase Amplitude Coupling
2025 47th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)Phase-amplitude coupling (PAC) is a fundamental neural phenomenon in which the phase of a slow oscillation modulates the amplitude of a faster oscillation. PAC has been implicated in various cognitive and clinical conditions, including Parkinson's disease, epilepsy, and depression.

The phase amplitude coupling to assess brain network system integration
2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA), 2016Brain Dynamics seems to be the most actual approach to the brain responses to external stimuli. Even if Event Related Potentials can be detected, the EEG band power perturbation and the Phase Amplitude Coupling (PAC) seems to be the most appropriate way to assess such a brain dynamics.

A Time-frequency Based Multivariate Phase-amplitude Coupling Measure
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019Interaction of neuronal oscillations across different frequency bands plays an important role in perception, attention, and memory. One particular form of interaction is the modulation of the amplitude of high-frequency oscillations by the phase of low-frequency oscillations, known as phase-amplitude coupling (PAC).

Dynamic Stereoelectroencephalography-Based Phase–Amplitude Coupling in Cingulate Epilepsy
International Journal of Neural SystemsAccurate localization of the theoretical epileptogenic zone in cingulate epilepsy is particularly challenging due to the region’s deep anatomical location and complex connectivity. While invasive stereoelectroencephalography (sEEG) methodology offers excellent spatiotemporal sampling of deep intracerebral structures, interpretation of these high ...
