TL;DR: Electroencephalography data indicate that collateral modulations of posterior α-activity, the momentary bias of visuospatial attention, and imminent visual processing are linked, and suggest that the Momentary direction of attention, predicting spatial biases in imminent visualprocessing, can be estimated from a lateralization index of posterior β-activity.

TL;DR: The data directly link momentary levels of posterior alpha-band activity to distinct states of visual cortex excitability, and suggest that their spontaneous fluctuation constitutes a visual operation mode that is activated automatically even without retinal input.

TL;DR: During voluntary orienting of attention, α‐synchronization is found to dominate over desynchronization, to be topographically specific for each of eight attention positions, and to occur over areas processing unattended space in a retinotopically organized pattern, which indicates that α‐ synchronized activity is an important component of selective attention, serving active suppression of unattended positions during visual spatial orienting.

TL;DR: The test in the human brain whether the oscillation in the alpha band is causally shaping perception through directly stimulating visual areas via short trains of rhythmic TMS shows that the posterior alpha rhythm is actively involved in shaping forthcoming perception and, hence, constitutes a substrate rather than a mere correlate of visual input regulation.

TL;DR: A neuroimaging study reveals how coupled brain oscillations at different frequencies align with quasi-rhythmic features of continuous speech such as prosody, syllables, and phonemes.
