Network analysis of EEG related functional MRI changes due to medication withdrawal in focal epilepsy

open access: yesNeuroImage: Clinical, 2015
Anti-epileptic drugs (AEDs) have a global effect on the neurophysiology of the brain which is most likely reflected in functional brain activity recorded with EEG and fMRI.

Statistical power and prediction accuracy in multisite resting-state fMRI connectivity

open access: yes, 2017
Connectivity studies using resting-state functional magnetic resonance imaging are increasingly pooling data acquired at multiple sites. While this may allow investigators to speed up recruitment or increase sample size, multisite studies also ...

EEG Alpha Power Modulation of fMRI Resting-State Connectivity [PDF]

open access: yesBrain Connectivity, 2012
In the past decade, the fast and transient coupling and uncoupling of functionally related brain regions into networks has received much attention in cognitive neuroscience. Empirical tools to study network coupling include functional magnetic resonance imaging (fMRI)-based functional and/or effective connectivity, and electroencephalography (EEG ...

Clinical applications of resting state functional connectivity

open access: yesFrontiers in Systems Neuroscience, 2010
During resting conditions the brain remains functionally and metabolically active. One manifestation of this activity that has become an important research tool is spontaneous fluctuations in the blood oxygen level dependent (BOLD) signal of fMRI.

Learning and comparing functional connectomes across subjects [PDF]

open access: yes, 2013
Functional connectomes capture brain interactions via synchronized fluctuations in the functional magnetic resonance imaging signal. If measured during rest, they map the intrinsic functional architecture of the brain.

Examining resting-state functional connectivity in first-episode schizophrenia with 7T fMRI and MEG

open access: yesNeuroImage: Clinical, 2019
Schizophrenia is often characterized by dysconnections in the brain, which can be estimated via functional connectivity analyses. Commonly measured using resting-state functional magnetic resonance imaging (fMRI) in order to characterize the intrinsic or

Information flow between resting state networks [PDF]

open access: yes, 2015
The resting brain dynamics self-organizes into a finite number of correlated patterns known as resting state networks (RSNs). It is well known that techniques like independent component analysis can separate the brain activity at rest to provide such ...

A study of neural activity and functional connectivity within the olfactory brain network in Parkinson's disease

open access: yesNeuroImage: Clinical, 2019
Olfactory dysfunction is an early manifestation of Parkinson's disease (PD). The present study aimed to illustrate potential differences between PD patients and healthy controls in terms of neural activity and functional connectivity within the olfactory

Loss of resting-state posterior cingulate flexibility is associated with memory disturbance in left temporal lobe epilepsy. [PDF]

open access: yesPLoS ONE, 2015
The association between cognition and resting-state fMRI (rs-fMRI) has been the focus of many recent studies, most of which use stationary connectivity.

Resting-State Functional Connectivity in Mathematical Expertise

open access: yesBrain Sciences, 2021
To what extent are different levels of expertise reflected in the functional connectivity of the brain? We addressed this question by using resting-state functional magnetic resonance imaging (fMRI) in mathematicians versus non-mathematicians.
