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

open access: yeseneuro, 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 ...

Evidence of amplitude modulation due to Resonant Mode Coupling in the delta Scuti star KIC5892969 [PDF]

open access: yes, 2015
A study of the star KIC5892969 observed by the Kepler satellite is presented. Its three highest amplitude modes present a strong amplitude modulation.

A computational study on altered theta-gamma coupling during learning and phase coding [PDF]

open access: yes, 2012
There is considerable interest in the role of coupling between theta and gamma oscillations in the brain in the context of learning and memory. Here we have used a neural network model which is capable of producing coupling of theta phase to gamma ...

Perspective: Phase Amplitude Coupling–Based Phase–Dependent Neuromodulation in Parkinson’s Disease

open access: yesFrontiers in Neuroscience, 2020
Deep brain stimulation (DBS) is an effective surgical therapy for Parkinson’s disease (PD). However, limitations of the DBS systems have led to great interest in adaptive neuromodulation systems that can dynamically adjust stimulation parameters to meet ...

Free core nutation: new large disturbance and connection evidence with geomagnetic jerks [PDF]

open access: yes, 2015
Variations in free core nutation (FCN) are connected with various processes in the Earth's fluid core and core-mantle coupling, which are also largely responsible for the geomagnetic field variations, particularly the geomagnetic jerks (GMJs). A previous

Misidentifications of specific forms of cross-frequency coupling: three warnings

open access: yesFrontiers 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]

open access: yesPLoS 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.
