The relationship between evoked and induced EEG/MEG changes: going beyond labels

Research output: Chapter in Book/Report/Conference proceedingChapter (peer-reviewed)peer-review


Researchers using EEG/MEG to study the link between brain activity and cognition have relied on one central tenant: the event-locked averaging of single trials of activity in the time-domain will result in the cancellation of any aspect of the signal not time-locked AND phase-locked to the event. However, while this assumption has led to a wealth of discoveries about how the brain processes information from the outside world, there is evidence that it’s not necessarily correct. In the current chapter, I will go over the evidence that the ongoing electrophysiological signals detected at the scalp can never entirely be averaged out. Moreover, I will argue that this assumption has led to the labelling of the different types of event-related changes to the EEG/MEG which while making the interpretations of data easier can serve to limit the questions we can ask about how the brain functions.
