Functional connectivity hubs in the human brain
Brain networks appear to have few and well localized regions with high functional connectivity density (hubs) for fast integration of neural processing, and their dysfunction could contribute to neuropsychiatric diseases. However the variability in the distribution of these brain hubs is unknown due in part to the overwhelming computational demands associated to their localization. Recently we ...
متن کاملFunctional connectivity hubs of the mouse brain
Recent advances in functional connectivity methods have made it possible to identify brain hubs - a set of highly connected regions serving as integrators of distributed neuronal activity. The integrative role of hub nodes makes these areas points of high vulnerability to dysfunction in brain disorders, and abnormal hub connectivity profiles have been described for several neuropsychiatric diso...
متن کاملFunctional Connectivity Hubs and Networks in the Awake Marmoset Brain
In combination with advances in analytical methods, resting-state fMRI is allowing unprecedented access to a better understanding of the network organization of the brain. Increasing evidence suggests that this architecture may incorporate highly functionally connected nodes, or "hubs", and we have recently proposed local functional connectivity density (lFCD) mapping to identify highly-connect...
متن کاملFunctional Connectivity Hubs and Modules in Resting-state Rat Brain
Introduction: Resting state fMRI (rs-fMRI) is widely used to investigate the brain’s intrinsic organizational structure in humans (for review see [1]) and is currently evaluated for its diagnostic and potentially prognostic value in elucidating the relationship between abnormal functional connectivity networks (FCN) and neuropsychiatric disorders such as Alzheimer’s disease, schizophrenia and a...
متن کاملAssociation between functional connectivity hubs and brain networks.
Functional networks are usually accessed with "resting-state" functional magnetic resonance imaging using preselected "seeds" regions. Frequently, however, the selection of the seed locations is arbitrary. Recently, we proposed local functional connectivity density mapping (FCDM), an ultrafast data-driven to locate highly connected brain regions (functional hubs). Here, we used the functional h...
