Ultra-slow oscillations in fMRI and resting-state connectivity: neuronal and vascular contributions and technical confounds
Summary Ultra-slow,∼ 0.1-Hz variations in the oxygenation level of brain blood are widely
used as an fMRI-based surrogate of" resting-state" neuronal activity. The temporal …

Disruptions of network connectivity predict impairment in multiple behavioral domains after stroke
Deficits following stroke are classically attributed to focal damage, but recent evidence
suggests a key role of distributed brain network disruption. We measured resting functional …

Sources and implications of whole-brain fMRI signals in humans
Whole-brain fMRI signals are a subject of intense interest: variance in the global fMRI signal
(the spatial mean of all signals in the brain) indexes subject arousal, and psychiatric …

The global signal in fMRI: Nuisance or Information?
The global signal is widely used as a regressor or normalization factor for removing the
effects of global variations in the analysis of functional magnetic resonance imaging (fMRI) …

Re-emergence of modular brain networks in stroke recovery
Studies of stroke have identified local reorganization in perilesional tissue. However,
because the brain is highly networked, strokes also broadly alter the brain's global network …

Low frequency systemic hemodynamic “noise” in resting state BOLD fMRI: characteristics, causes, implications, mitigation strategies, and applications
Advances in functional magnetic resonance imaging (fMRI) acquisition have improved
signal to noise to the point where the physiology of the subject is the dominant noise source …

Structural disconnections explain brain network dysfunction after stroke
Stroke causes focal brain lesions that disrupt functional connectivity (FC), a measure of
activity synchronization, throughout distributed brain networks. It is often assumed that FC …

[HTML][HTML] Resting-state “physiological networks”
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 …

Cerebrovascular reactivity mapping without gas challenges: a methodological guide
Cerebrovascular reactivity (CVR) is defined as the ability of vessels to alter their caliber in
