Network connectivity in epilepsy: Resting state-fMRI and EEG-fMRI contributions [PDF]
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.

Caffeine-Induced Global Reductions in Resting-state BOLD Connectivity reflect Widespread Decreases in MEG Connectivity [PDF]
Frontiers in Human Neuroscience, 2013 In resting-state functional magnetic resonance imaging (fMRI), the temporal correlation between spontaneous fluctuations of the blood oxygenation level dependent (BOLD) signal from different brain regions is used to assess functional connectivity ...

State-Dependent Effective Connectivity in Resting-State fMRI [PDF]
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 ...

A comparison of resting state functional magnetic resonance imaging to invasive electrocortical stimulation for sensorimotor mapping in pediatric patients [PDF]
NeuroImage: Clinical, 2019 Localizing neurologic function within the brain remains a significant challenge in clinical neurosurgery. Invasive mapping with direct electrocortical stimulation currently is the clinical gold standard but is impractical in young or cognitively delayed ...

Resting State fMRI: Going Through the Motions [PDF]
Frontiers in Neuroscience, 2019 Resting state functional magnetic resonance imaging (rs-fMRI) has become an indispensable tool in neuroscience research. Despite this, rs-fMRI signals are easily contaminated by artifacts arising from movement of the head during data collection.

On consciousness, resting state fMRI, and neurodynamics [PDF]
Nonlinear Biomedical Physics, 2010 During the last years, functional magnetic resonance imaging (fMRI) of the brain has been introduced as a new tool to measure consciousness, both in a clinical setting and in a basic neurocognitive research. Moreover, advanced mathematical methods and theories have arrived the field of fMRI (e.g.

Resting-state fMRI confounds and cleanup [PDF]
NeuroImage, 2013 The goal of resting-state functional magnetic resonance imaging (fMRI) is to investigate the brain's functional connections by using the temporal similarity between blood oxygenation level dependent (BOLD) signals in different regions of the brain "at rest" as an indicator of synchronous neural activity.

Resting-State fMRI in Studies of Acupuncture [PDF]
Evidence-Based Complementary and Alternative Medicine, 2021 Research exploring the mechanism of acupuncture has been a hot topic in medicine. Resting-state functional magnetic resonance imaging (rs-fMRI) research is a noninvasive and extensive method, which is aimed at the research of the mechanism of acupuncture. Researchers use fMRI technologies to inspect the acupuncture process.

An approach for identifying brainstem dopaminergic pathways using resting state functional MRI. [PDF]
, 2014 Here, we present an approach for identifying brainstem dopaminergic pathways using resting state functional MRI. In a group of healthy individuals, we searched for significant functional connectivity between dopamine-rich midbrain areas (substantia nigra;
