The violation of these automatically made predictions lead to the observation of so called [[Event-related potential|ERPs]] (event related potential, a stereotyped electrophysiological response to an internal or external stimulus). Two forms of ERPs can be detected in the context of processing music. One is the [[Mismatch negativity|MMN]] (mismatch negativity), which has first been investigated only with physical deviants like [[frequency]], [[sound intensity]],{{Disambiguation needed|date=June 2011}} [[timbre]] deviants (referred to as [[phMMN]]) and could now also be shown for changes of abstract auditory features like tone pitches (referred to as [[afMMN]]). The other one is the so called [[Electroencephalography|ERAN]] (early right anterior negativity) which can be elicited by syntactic irregularities in music. Both the ERAN and the MMN are ERPs indicating a mismatch between predictions based on regularities and actually experienced acoustic information. As for a long time it seemed to be, that the ERAN is a special variant of the MMN, the question arises, why they are told apart today. There are several differences between the MMN and the ERAN found in the last years:
