TLDR
Continuous and simultaneous EEG/fMRI is implemented to identify BOLD signal changes related to spontaneous power fluctuations in the alpha rhythm, the dominant EEG pattern during relaxed wakefulness, and a strong negative correlation of parietal and frontal cortical activity with alpha power was found.Citations

Spontaneous fluctuations in brain activity observed with functional magnetic resonance imaging.
Michael D. Fox,Marcus E. Raichle +1 more
TL;DR: Recent studies examining spontaneous fluctuations in the blood oxygen level dependent (BOLD) signal of functional magnetic resonance imaging as a potentially important and revealing manifestation of spontaneous neuronal activity are reviewed.
Journal ArticleDOI
EEG alpha oscillations: The inhibition–timing hypothesis
TL;DR: The general conclusion is that alpha ERS plays an active role for the inhibitory control and timing of cortical processing whereas ERD reflects the gradual release of inhibition associated with the emergence of complex spreading activation processes.

Shaping functional architecture by oscillatory alpha activity : gating by inhibition
Ole Jensen,Ali Mazaheri +1 more
TL;DR: It is proposed that information is gated by inhibiting task-irrelevant regions, thus routing information to task-relevant regions and the empirical support for this framework is discussed.

Glover,Javier Gonzalez-Castillo,Daniel A. Handwerker,Shella D. Keilholz,Vesa Kiviniemi,David A. Leopold,Francesco de Pasquale,Olaf Sporns,Martin Walter,Martin Walter,Catie Chang +21 more
TL;DR: Emerging evidence suggests that dynamic FC metrics may index changes in macroscopic neural activity patterns underlying critical aspects of cognition and behavior, though limitations with regard to analysis and interpretation remain.

Electrophysiological signatures of resting state networks in the human brain.
TL;DR: This work has identified six widely distributed resting state networks and supports for the first time in humans the coalescence of several brain rhythms within large-scale brain networks as suggested by biophysical studies.

A mathematical theory of communication
TL;DR: This final installment of the paper considers the case where the signals or the messages or both are continuously variable, in contrast with the discrete nature assumed until now.

The mathematical theory of communication
Claude E. Shannon,Warren Weaver +1 more
TL;DR: The Mathematical Theory of Communication (MTOC) as discussed by the authors was originally published as a paper on communication theory more than fifty years ago and has since gone through four hardcover and sixteen paperback printings.
Journal ArticleDOI
Control of goal-directed and stimulus-driven attention in the brain
TL;DR: Evidence for partially segregated networks of brain areas that carry out different attentional functions is reviewed, finding that one system is involved in preparing and applying goal-directed selection for stimuli and responses, and the other is specialized for the detection of behaviourally relevant stimuli.
Journal ArticleDOI
The Mathematical Theory of Communication
TL;DR: The theory of communication is extended to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the original message anddue to the nature of the final destination of the information.

TL;DR: In this paper, the authors present a general approach that accommodates most forms of experimental layout and ensuing analysis (designed experiments with fixed effects for factors, covariates and interaction of factors).
