Elevated phase amplitude coupling as a depression biomarker in epilepsy. [PDF]

Epilepsy Behav
Depression 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 ...

Corticostriatal Coordination through Coherent Phase-Amplitude Coupling [PDF]

The Journal of Neuroscience, 2014
The corticostriatal axis is the main input stage of the basal ganglia and is crucial for their role in motor behavior. Synchronized oscillations might mediate interactions between cortex and striatum during behavior, yet direct evidence remains sparse. Here, we show that, during motor behavior, low- and high-frequency oscillations jointly couple cortex

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.

A neural mass model of cross frequency coupling. [PDF]

PLoS ONE, 2017
Electrophysiological signals of cortical activity show a range of possible frequency and amplitude modulations, both within and across regions, collectively known as cross-frequency coupling.

Discriminating Valid from Spurious Indices of Phase-Amplitude Coupling [PDF]

eneuro, 2016
AbstractRecently there has been a strong interest in cross-frequency coupling, the interaction between neuronal oscillations in different frequency bands. In particular, measures quantifying the coupling between the phase of slow oscillations and the amplitude of fast oscillations have been applied to a wide range of data recorded from animals and ...

Effect of Phase Clustering Bias on Phase-Amplitude Coupling for Emotional EEG

Journal of Integrative Neuroscience
Background: Emotions are thought to be related to distinct patterns of neural oscillations, but the interactions among multi-frequency neural oscillations during different emotional states lack full exploration.

Lack of redundancy between electrophysiological measures of long-range neuronal communication

BMC Biology, 2021
Background Communication between brain areas has been implicated in a wide range of cognitive and emotive functions and is impaired in numerous mental disorders.

Decreased Phase–Amplitude Coupling Between the mPFC and BLA During Exploratory Behaviour in Chronic Unpredictable Mild Stress-Induced Depression Model of Rats

Frontiers in Behavioral Neuroscience, 2021
Depression is a common neuropsychiatric illness observed worldwide, and reduced interest in exploration is one of its symptoms. The control of dysregulated medial prefrontal cortex (mPFC) over the basolateral amygdala (BLA) is related to depression ...

Measuring Phase–Amplitude Coupling Effect with OPM-MEG

Photonics
Optically pumped magnetometers (OPMs) present a promising opportunity to advance magnetoencephalography (MEG), enhancing the accuracy of neuronal activity recordings due to their high spatiotemporal resolution.

Improving emotional-action control by targeting long-range phase-amplitude neuronal coupling

eLife, 2020
Control over emotional action tendencies is essential for everyday interactions. This cognitive function fails occasionally during socially challenging situations, and systematically in social psychopathologies. We delivered dual-site phase-coupled brain
