In response to this process, the low amplitude, high frequency, spatially differentiated EEG of wakefulness is replaced by a large amplitude, low frequency, spatially synchronous EEG waveform.

The hypothesis of linking PR during the background spontaneous EEG provides a new definition of the term “desynchronization” used to describe ERD and the waxing and waning of the spontaneous EEG. That is desynchronization is actually “spatially differentiated phase reset” or “micro bonding” of local clusters of neurons connected across long distances to other local clusters for brief periods of time.

Usually, several electrodes are distributed across the skull in order to allow for a spatially differentiated measurement of brain activity.

The timecourse of event-related attenuations in alpha-band EEG was first quantified by Pfurtscheller (1977), using a term, event-related desynchronization (ERD), derived from the concept that cortical arousal involves "desynchronization" of relatively slow, spatiotemporally coherent cortical rhythms, and their replacement with faster, more spatially differentiated activity.
