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 ...

Assessing dynamic functional connectivity in heterogeneous samples [PDF]
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.

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 ...

Dynamic functional connectivity: Why the controversy? [PDF]
Imaging Neurosci (Camb), 2023 Abstract In principle, dynamic functional connectivity in fMRI is just a statistical measure. A passer-by might think it to be a specialist topic, but it continues to attract widespread attention and spark controversy. Why?

Dynamic Functional Connectivity in the Musical Brain [PDF]
, 2019 Musical training causes structural and functional changes in the brain due to its sensory-motor demands. This leads to differences in how musicians perceive and process music as compared to non-musicians, thereby providing insights into brain adaptations and plasticity.

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 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

Dynamic Properties of Functional Connectivity in the Rodent [PDF]
Brain Connectivity, 2013 Functional connectivity mapping with resting-state magnetic resonance imaging (MRI) has become an immensely powerful technique that provides insight into both normal cognitive function and disruptions linked to neurological disorders. Traditionally, connectivity is mapped using data from an entire scan (minutes), but it is well known that cognitive ...
