Background Functional connectivity (FC) measures statistical dependence between cortical
brain regions. Studies of FC facilitate understanding of the brain's function and architecture …

Estimation of functional connectivity (FC) has become an increasingly powerful tool for
investigating healthy and abnormal brain function. Static connectivity, in particular, has …

Epilepsy is a neurological disorder characterized by recurrent epileptic seizures. The
involvement of abnormal functional brain networks in the development of epilepsy and its …

Previous research suggests that age-related differences in attention reflect the interaction of
top-down and bottom-up processes, but the cognitive and neural mechanisms underlying …

Objective A fundamental challenge in treating epilepsy is that changes in observed seizure
frequencies do not necessarily reflect changes in underlying seizure risk. Rather, changes in …

Brain function emerges from the collective interactions of distributed brain regions. A central
effort in the analysis of functional imaging data has been to elucidate the spatial topologies …

Despite subjective cognitive decline (SCD), a preclinical stage of Alzheimer's disease (AD),
being widely studied in recent years, studies on centrality frequency in individuals with SCD …

Resting-state functional magnetic resonance imaging (fMRI) studies using static functional
connectivity (sFC) measures have shown that the brain function is severely disrupted after …

A common assumption in the study of brain functional connectivity is that the brain network is
stationary. However it is increasingly recognized that the brain organization is prone to …

Alzheimer's disease (AD) is the main cause of dementia in the elderly. To date, it remains
largely unknown whether and how dynamic characteristics of the functional networks differ …
