Clustering of resting state networks. [PDF]

PLoS ONE, 2012
The goal of the study was to demonstrate a hierarchical structure of resting state activity in the healthy brain using a data-driven clustering algorithm.The fuzzy-c-means clustering algorithm was applied to resting state fMRI data in cortical and ...

Resting-state “physiological networks”

NeuroImage, 2020
Slow changes in systemic brain physiology can elicit large fluctuations in fMRI time series, which manifest as structured spatial patterns of temporal correlations between distant brain regions. Here, we investigated whether such “physiological networks”—

The Amsterdam Resting-State Questionnaire reveals multiple phenotypes of resting-state cognition [PDF]

Frontiers in Human Neuroscience, 2013
Resting-state neuroimaging is a dominant paradigm for studying brain function in health and disease. It is attractive for clinical research because of its simplicity for patients, straightforward standardization, and sensitivity to brain disorders ...

Metastable Resting State Brain Dynamics [PDF]

Frontiers in Computational Neuroscience, 2019
Metastability refers to the fact that the state of a dynamical system spends a large amount of time in a restricted region of its available phase space before a transition takes place, bringing the system into another state from where it might recur into

Electroencephalographic Microstates in Schizophrenia and Bipolar Disorder

Frontiers in Psychiatry, 2021
Schizophrenia (SCH) and bipolar disorder (BD) are characterized by many types of symptoms, damaged cognitive function, and abnormal brain connections. The microstates are considered to be the cornerstones of the mental states shown in EEG data.

Resting state functional connectivity in perfusion imaging: correlation maps with BOLD connectivity and resting state perfusion. [PDF]

PLoS ONE, 2011
Functional connectivity is a property of the resting state that may provide biomarkers of brain function and individual differences. Classically, connectivity is estimated as the temporal correlation of spontaneous fluctuations of BOLD signal.

Intraoperative Resting-State Functional Connectivity Based on RGB Imaging

Diagnostics, 2021
RGB optical imaging is a marker-free, contactless, and non-invasive technique that is able to monitor hemodynamic brain response following neuronal activation using task-based and resting-state procedures. Magnetic resonance imaging (fMRI) and functional

Network connectivity in epilepsy: Resting state-fMRI and EEG-fMRI contributions

Frontiers in Neurology, 2014
There is a growing body of evidence pointing towards large scale networks underlying the core phenomena in epilepsy, from seizure generation to cognitive dysfunction or response to treatment.

State-Dependent Effective Connectivity in Resting-State fMRI

Frontiers in Neural Circuits, 2021
The human brain at rest exhibits intrinsic dynamics transitioning among the multiple metastable states of the inter-regional functional connectivity. Accordingly, the demand for exploring the state-specific functional connectivity increases for a deeper ...

The VWFA: It’s Not Just for Words Anymore

Frontiers in Human Neuroscience, 2014
Reading is an important but phylogenetically new skill. While neuroimaging studies have identified brain regions used in reading, it is unclear to what extent these regions become specialized for use predominantly in reading versus other tasks.
