Modification of scale-free electrophysiological activity induced by changes in excitatory-inhibitory balance is governed by the dynamics of multiple oscillatory relaxation processes [article]

Suresh Daniel Muthukumaraswamy, David TJ Liley
2017 bioRxiv   pre-print
We develop and test a unifying model which can explain, the 1/f nature of electrophysiological spectra, their dynamic interaction with oscillatory rhythms as well as the sensitivity of 1/f activity to  ...  excitation-inhibition balance by considering electrophysiological spectra as being generated by a collection of stochastically perturbed damped oscillators having a distribution of relaxation rates.  ...  As mentioned, previous work has 479 demonstrated that scale-free, 1/f activity can be modified by task states 7, 13 and can be altered in 480 special populations suggesting functional relevance 11, 45  ...

Mate Gyurkovics, Grace M Clements, Kathy A Low, Monica Fabiani, Gabriele Gratton
2020 bioRxiv   pre-print
Using resting-state EEG data from 80 participants, we found that the level of 1/f activity and alpha power are not positively correlated within participants, in line with the additive but not the multiplicative  ...  Typically, time-frequency analysis (TFA) of electrophysiological data is aimed at isolating narrowband signals (oscillatory activity) from broadband non-oscillatory (1/f) activity, so that changes in oscillatory  ...  J.

Mouse Activity across Time Scales: Fractal Scenarios

G. Z. dos Santos Lima, B. Lobão-Soares, G. C. do Nascimento, Arthur S. C. França, L. Muratori, S. Ribeiro, G. Corso, Clayton T. Dickson
2014 PLoS ONE  
In both situations we find roughly the same pattern: for short time intervals we observe high correlation in activity -a typical 1/f complex pattern -while for large time intervals there is anti-correlation  ...  Furthermore, we find that the waking state is characterized by longer time scales than SWS and by a softer transition from correlation to anticorrelation.  ...  Finally, the accelerometerbased DFA analysis can be used as a robust tool for evaluating promising therapies in models of motor alterations induced by drugs or in neuromuscular diseases.  ...

Resting-State Pallidal-Cortical Oscillatory Couplings in Patients With Predominant Phasic and Tonic Dystonia

2018 Frontiers in Neurology  
Pallidal deep brain stimulation (DBS) improves the symptoms of dystonia. The improvement processes of dystonic movements (phasic symptoms) and tonic symptoms differ.  ...  In phasic patients, the alpha spectral peaks emerged in the GPi oscillatory activities, and alpha GPi coherence with the GPe and MCx was higher than in tonic patients.  ...  Patients were instructed to lie in the supine position and to be awake in the relaxed condition with eyes closed for around 10 min.  ...

Robert Becker, Alexis Hervais-Adelman
2020 eNeuro  
The functional roles of these resting-state networks are yet to be fully elucidated.  ...  Examination of inter-areal coupling of resting state oscillatory activity has revealed that the brain's resting activity is composed of functional networks, whose topographies differ depending upon oscillatory  ...  In fact, one could go even further and claim that all oscillatory activity is only one part of the broader picture of neuronal dynamics and including 1/f dynamics is a crucial extension of describing neuronal  ...
