The amplitude of the resting-state fMRI global signal is related to EEG vigilance measures

TLDR
The amplitude of the global signal exhibited a significant negative correlation with EEG vigilance across subjects studied in the eyes-closed condition and increases in EEG vigilance were significantly associated with both a decrease in global signal amplitude and an increase in the average level of anti-correlation between the default mode network and the task-positive network.

Frequency-specific altered global signal topography in drug-naïve first-episode patients with adolescent-onset schizophrenia.

TL;DR: The influence of the GS on brain networks altered in a frequency-specific way in schizophrenia, and significant frequency-by-group interaction was observed in the frontoparietal network.

Multi-band MEG signatures of BOLD connectivity reorganization during visuospatial attention.

TL;DR: In this article, the authors reported behaviorally relevant BOLD-FC modulations between visual and dorsal attention regions when subjects performed a visuospatial attention task as compared to central fixation.

Physiological and head motion signatures in static and time-varying functional connectivity and their subject discriminability

TL;DR: It is found that head motion, as well as heart rate and breathing fluctuations, induce artifactual connectivity within distinct resting-state networks and that they correlate with recurrent patterns in time-varying FC.

Mind blanking is a distinct mental state linked to a recurrent brain profile of globally positive connectivity during ongoing mentation

TL;DR: In this paper , the authors used fMRI experience-sampling to characterize the brain's neurobehavioral profile with the aim to delineate its role during ongoing mentation, showing that MB is reported less frequently, faster, and with low transitional dynamics among other mental states, pointing to its role as a transient mental relay.

EEGLAB: an open source toolbox for analysis of single-trial EEG dynamics including independent component analysis.

TL;DR: EELAB as mentioned in this paper is a toolbox and graphic user interface for processing collections of single-trial and/or averaged EEG data of any number of channels, including EEG data, channel and event information importing, data visualization (scrolling, scalp map and dipole model plotting, plus multi-trial ERP-image plots), preprocessing (including artifact rejection, filtering, epoch selection, and averaging), Independent Component Analysis (ICA) and time/frequency decomposition including channel and component cross-coherence supported by bootstrap statistical methods based on data resampling.

Advances in functional and structural MR image analysis and implementation as FSL.

TL;DR: A review of the research carried out by the Analysis Group at the Oxford Centre for Functional MRI of the Brain (FMRIB) on the development of new methodologies for the analysis of both structural and functional magnetic resonance imaging data.

A default mode of brain function.

TL;DR: A baseline state of the normal adult human brain in terms of the brain oxygen extraction fraction or OEF is identified, suggesting the existence of an organized, baseline default mode of brain function that is suspended during specific goal-directed behaviors.

AFNI: software for analysis and visualization of functional magnetic resonance neuroimages

TL;DR: A package of computer programs for analysis and visualization of three-dimensional human brain functional magnetic resonance imaging (FMRI) results is described and techniques for automatically generating transformed functional data sets from manually labeled anatomical data sets are described.

Functional connectivity in the motor cortex of resting human brain using echo-planar MRI.

TL;DR: It is concluded that correlation of low frequency fluctuations, which may arise from fluctuations in blood oxygenation or flow, is a manifestation of functional connectivity of the brain.
