Is Cortical Theta-Gamma Phase-Amplitude Coupling Memory-Specific? [PDF]
Brain Sciences, 2022 One of the proposed neural mechanisms involved in working memory is coupling between the theta phase and gamma amplitude. For example, evidence from intracranial recordings shows that coupling between hippocampal theta and cortical gamma oscillations ...

State space methods for phase amplitude coupling analysis [PDF]
Scientific Reports, 2022 Phase amplitude coupling (PAC) is thought to play a fundamental role in the dynamic coordination of brain circuits and systems. There are however growing concerns that existing methods for PAC analysis are prone to error and misinterpretation.

Magnetoencephalography detects phase-amplitude coupling in Parkinson’s disease [PDF]
Scientific Reports, 2022 To characterize Parkinson’s disease, abnormal phase-amplitude coupling is assessed in the cortico-basal circuit using invasive recordings. It is unknown whether the same phenomenon might be found in regions other than the cortico-basal ganglia circuit ...

Theta-gamma phase amplitude coupling in a hippocampal CA1 microcircuit. [PDF]
PLoS Computational Biology, 2023 Phase amplitude coupling (PAC) between slow and fast oscillations is found throughout the brain and plays important functional roles. Its neural origin remains unclear. Experimental findings are often puzzling and sometimes contradictory.

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

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.

Theta-gamma phase-amplitude coupling in psychosis and healthy controls: Predicting working memory capacity across different tasks [PDF]
NeuroImage: ClinicalTheta-gamma phase-amplitude coupling has been proposed as a possible mechanism underlying working memory. Here, we assess whether cortical theta-gamma phase-amplitude coupling is related to working memory deficits in patients with psychosis, and whether ...

Phase-amplitude coupling-based adaptive filters for neural signal decoding [PDF]
Frontiers in Neuroscience, 2023 Bandpass filters play a core role in ECoG signal processing. Commonly used frequency bands such as alpha, beta, and gamma bands can reflect the normal rhythm of the brain. However, the universally predefined bands might not be optimal for a specific task.

Effect of the addition of a low-dose of ketamine to propofol anaesthesia on the phase-amplitude coupling features of an electroencephalogram [PDF]
BJA OpenBackground: Low-dose ketamine as an adjunct to propofol-based total intravenous anaesthesia (TIVA) complicates hypnotic depth monitoring by increasing bispectral index values and altering electroencephalogram (EEG).
