[HTML][HTML] Resting state MEG oscillations show long-range temporal correlations of phase synchrony that break down during finger movement

M Botcharova, L Berthouze, MJ Brookes… - Frontiers in …, 2015 - frontiersin.org
The capacity of the human brain to interpret and respond to multiple temporal scales in its
surroundings suggests that its internal interactions must also be able to operate over a broad …

A maximum likelihood based technique for validating detrended fluctuation analysis (ML-DFA)

M Botcharova, SF Farmer, L Berthouze - arXiv preprint arXiv:1306.5075, 2013 - arxiv.org
Detrended Fluctuation Analysis (DFA) is widely used to assess the presence of long-range
temporal correlations in time series. Signals with long-range temporal correlations are …

Power-law distribution of phase-locking intervals does not imply critical interaction

M Botcharova, SF Farmer, L Berthouze - Physical Review E, 2012 - APS
Neural synchronization plays a critical role in information processing, storage, and transmission.
Characterizing the pattern of synchronization is therefore of great interest. It has recently …
