TL;DR: It is proposed that simultaneous α-, β- (14–30Hz) and γ- (30–70Hz) frequency band oscillations are required for unified cognitive operations, and hypothesize that cross-frequency phase synchrony between α, β and ι oscillations coordinates the selection and maintenance of neuronal object representations during working memory, perception and consciousness.

TL;DR: It is demonstrated, using magnetoencephalography, that robust cross-frequency phase synchrony is present in the human cortex among oscillations with frequencies from 3 to 80 Hz and that it is modulated by cognitive task demands.

TL;DR: Data suggest that interareal phase synchrony in the α-, β-, and γ-frequency bands among frontoparietal and visual regions could be a systems level mechanism for coordinating and regulating the maintenance of neuronal object representations in VWM.

TL;DR: It is concluded that ongoing 0.01–0.1 Hz EEG fluctuations are prominent and functionally significant during execution of cognitive tasks, suggesting that the infraslow fluctuations reflect the excitability dynamics of cortical networks.

TL;DR: In this article, the authors used source reconstructed magneto-and electroencephalographic recordings to characterize the dynamics of ongoing cortical activity and found robust power-law scaling in neuronal LRTCs and avalanches in resting-state data and during the performance of audiovisual threshold stimulus detection tasks.
