Event-related synchronization (ERS) in the alpha band — an electrophysiological correlate of cortical idling: A review

Pfurtscheller, G., Stancák, A., Neuper, Ch.·1996·International Journal of Psychophysiology

Abstract

EEG desynchronization is a reliable correlate of excited neural structures of activated cortical areas. EEG synchronization within the alpha band may be an electrophysiological correlate of deactivated cortical areas. Such areas are not processing sensory information or motor output and can be considered to be in an idling state. One example of such an idling cortical area is the enhancement of mu rhythms in the primary hand area during visual processing or during foot movement. In both circumstances, the neurons in the hand area are not needed for visual processing or preparation for foot movement. As a result of this, an enhanced hand area mu rhythm can be observed.

  • Cortical oscillations in the alpha band (8-14 Hz), previously considered an idling rhythm increasing in power at rest, have more recently been linked to ignoring task-irrelevant information.

    “Electroencephalography (EEG) studies have shown that cortical oscillations in the alpha band (8–14 Hz), previously considered an “idling” rhythm increasing in power at rest90, has more recently been linked to ignoring of task-irrelevant information (for review see ref. 91).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
