Activated permutation entropy for graph signals

Om Roy, Avalon Campbell-Cousins, John Stewart Fabila Carrasco, Mario A. Parra et autres

Nonlinear dynamics play an important role in the analysis of signals. A popular, readily interpretable nonlinear measure is Permutation Entropy (PE). PE has recently been extended for the analysis of graph signals, thus providing a framework for non-linear analysis of data sampled …

Source-space EEG alpha activity reveals brain age gaps due to neurodegeneration and disparity

Mónica Otero, Felipe I. Carriel-Rubilar, Hernan Hernandez, Jhosmary Cuadros et autres

Brain clocks are promising tools for evaluating brain health. However, most current methods rely on structural neuroimaging. Functionally based approaches remain scarce, especially for assessing age-related neurodegenerative diseases. This study examines whether the brain age gap (BAG), the difference between chronological and …

The exposome of brain aging across 34 countries

Agustina Legaz, Sebastián Moguilner, Pablo Barttfeld, Jhosmary Cuadros Castro et autres

The physical and social exposome affects human aging, and brain clocks may track its effects. However, most studies neglect multidomain exposures (physical, social and political) across diverse settings globally and their associations with brain aging. In this study, we characterized the associations …
