Tracking functional network connectivity dynamics in the elderly
Frontiers in Neuroscience, 2023 IntroductionFunctional magnetic resonance imaging (fMRI) has shown that aging disturbs healthy brain organization and functional connectivity. However, how this age-induced alteration impacts dynamic brain function interaction has not yet been fully ...

Multimodal imaging of brain dynamic functional connectivity [PDF]
Frontiers in Neurology, 2015 The study of large-scale functional interactions in the human brain with fMRI extends almost to the first applications of this technology. Due to historical reasons and preconceptions about the limitations of this brain imaging method, most studies have ...

Dynamic Functional Brain Connectivity for Face Perception [PDF]
Frontiers in Human Neuroscience, 2015 Face perception is mediated by a distributed brain network comprised of the core system at occipito-temporal areas and the extended system at other relevant brain areas involving bilateral hemispheres. In this study we explored how the brain connectivity

Assessing dynamic functional connectivity in heterogeneous samples
NeuroImage, 2017 Several methods have been developed to measure dynamic functional connectivity (dFC) in fMRI data. These methods are often based on a sliding-window analysis, which aims to capture how the brain's functional organization varies over the course of a scan.

A Statistical Characterization of Dynamic Brain Functional Connectivity
Human Brain MappingABSTRACTThis study examined the statistical underpinnings of dynamic functional connectivity in mental disorders, using resting‐state fMRI signals. Notably, there has been an absence of research demonstrating the non‐stationarity of the empirical probability distribution of functional connectivity.

Dynamic network centrality summarizes learning in human brain [PDF]
, 2013 We study functional activity in the human brain using functional Magnetic Resonance Imaging and recently developed tools from network science. The data arise from the performance of a simple behavioural motor learning task.

Topography of functional connectivity in human multichannel EEG during second language processing [PDF]
We analyze the topography of nonlinear interdependence in the EEG of two group German-native speakers, divided according to their English proficiency level (high or low), when listening to one text in German and one in English.

Assessing uncertainty in dynamic functional connectivity [PDF]
NeuroImage, 2017 Functional connectivity (FC) - the study of the statistical association between time series from anatomically distinct regions (Friston, 1994, 2011) - has become one of the primary areas of research in the field surrounding resting state functional magnetic resonance imaging (rs-fMRI). Although for many years researchers have implicitly assumed that FC
