TLDR
Event-related desynchronization is the short-lasting attenuation or blocking of rhythms within the alpha (beta) band and reflects primary visual processing and feature extraction, the latter is more related to cognitive processing and mechanisms of attention.Citations

Rhythms of the brain
TL;DR: The brain's default state: self-organized oscillations in rest and sleep, and perturbation of the default patterns by experience.

α-Band Electroencephalographic Activity over Occipital Cortex Indexes Visuospatial Attention Bias and Predicts Visual Target Detection
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.

Measuring neurophysiological signals in aircraft pilots and car drivers for the assessment of mental workload, fatigue and drowsiness.
TL;DR: Review of the literature suggests that there exists a coherent sequence of changes for EEG, EOG and HR variables during the transition from normal drive, high mental workload and eventually mental fatigue and drowsiness.

Imagery of motor actions: differential effects of kinesthetic and visual-motor mode of imagery in single-trial EEG.
TL;DR: To improve motor-imagery-based BCI control, user training should emphasize kinesthetic experiences instead of visual representations of actions.

High-frequency gamma oscillations and human brain mapping with electrocorticography.
TL;DR: These ECoG studies have confirmed and extended the original non-Invasive observations of ERD/ERS phenomena in lower frequencies, and have discovered novel event-related responses in gamma frequencies higher than those previously observed in non-invasive recordings.

Is the P300 component a manifestation of context updating
TL;DR: The amplitude of the P300 component is controlled multiplicatively by the subjective probability and task relevance of eliciting events, whereas its latency depends on the duration of stimulus evaluation as mentioned in this paper.

Neural mechanisms underlying brain waves: from neural membranes to networks.
TL;DR: In this review, a number of experimental findings and theoretical concepts that have led to new insights into the mechanisms underlying brain waves are presented and the possibility that neural networks may behave as complex dynamic systems with the properties of deterministic chaos is discussed.

Event-related synchronization (ERS): an electrophysiological correlate of cortical areas at rest.
TL;DR: It was found that alpha band activity can be enhanced over the visual region during a motor task, or during a visual task over the sensorimotor region, which means ERD and ERS can be observed at nearly the same time.

Comparison of subcortical, cortical and scalp activity using chronically indwelling electrodes in man.
TL;DR: Intracerebral recordings show that there is little field spread in brain tissue and that cerebral models with dipoles deep within the brain are not satisfactory and model experiments indicate that cortical areas of at least 6 sq cm must be involved in synchronous or near synchronous activity before the scalp EEG is observed, using standard working gains.

Patterns of cortical activation during planning of voluntary movement
TL;DR: The influence of planning of self-paced voluntary finger movements on alpha band components was studied and it is concluded that the side of movement is predetermined more than 1 sec before movement onset.
