Assessing the Impact of Ih Conductance on Cross-Frequency Coupling in Model Pyramidal Neurons [PDF]

open access: yesFrontiers in Computational Neuroscience, 2020
Large cortical and hippocampal pyramidal neurons are elements of neuronal circuitry that have been implicated in cross-frequency coupling (CFC) during cognitive tasks. We investigate potential mechanisms for CFC within these neurons by examining the role

Cross-frequency Coupling Within and Between the Human Thalamus and Neocortex [PDF]

open access: yesFrontiers in Human Neuroscience, 2013
There is currently growing interest in, and increasing evidence for, cross-frequency interactions between electrical field oscillations in the brains of various organisms. A number of theories have linked such interactions to crucial features of neuronal

Thalamo-cortical cross-frequency coupling detected with MEG [PDF]

open access: yesFrontiers in Human Neuroscience, 2014
Neural oscillations are observed across a variety of temporal and spatial scales, and are believed to play a key role in brain function. In addition to specific functional roles ascribed to isolated frequencies, it is likely that the interplay between activity at different frequencies plays an essential role in cognition and behavior (Canolty and ...

Untangling cross-regional cross-frequency coupling in dynamic neural oscillations. [PDF]

open access: yesJ Neural Eng
Abstract Objective. Brain networks communicate through long range phase coupling of low frequency oscillations (LFOs, less than 35 Hz) between brain regions. At the same time, phase-amplitude cross-frequency coupling (CFC), in which the phase of the same LFO have been shown to modulate the ...

Untangling cross-frequency coupling in neuroscience [PDF]

open access: yesCurrent Opinion in Neurobiology, 2014
Abstract Cross-frequency coupling (CFC) has been proposed to coordinate neural dynamics across spatial and temporal scales. Despite its potential relevance for understanding healthy and pathological brain function, the standard CFC analysis and physiological interpretation come with fundamental problems.

Theta-gamma phase-amplitude coupling: physiological basics, analysis methods, and perspectives of translation into clinical practice [PDF]

open access: yesАнналы клинической и экспериментальной неврологии, 2022
Studying rhythmic neural synchronization (cross-frequency coupling in various ranges) is an emerging topic in present-day neurophysiology. One of the best-studied cross-frequency couplings is theta-gamma phase-amplitude coupling that contributes to the ...

Slow oscillation‐spindle cross‐frequency coupling predicts overnight declarative memory consolidation in older adults

open access: yesEuropean Journal of Neuroscience, 2023
Cross‐frequency coupling (CFC) between brain oscillations during non‐rapid‐eye‐movement (NREM) sleep (e.g. slow oscillations [SO] and spindles) may be a neural mechanism of overnight memory consolidation.

Dissociating harmonic and non-harmonic phase-amplitude coupling in the human brain

open access: yesNeuroImage, 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
