Emergence of synchronous EEG spindles from asynchronous MEG spindles
Paper · 2011
Summary
While sleep spindles are traditionally viewed as synchronous brain-wide events, this research demonstrates they actually emerge from a much more dynamic, focal process. Most spindles begin as localized, asynchronous oscillations-detectable only by MEG—before recruiting a "critical mass" of cortical surface area to finally appear as a synchronous wave on the EEG. Essentially, MEG captures the private, early "spark" of a spindle in specific brain regions, whereas EEG records the eventual "forest fire" of global synchronization that follows about 200 milliseconds later.
