Carrier-frequency specific omission-related neural activity in ordered sound sequences are independent of omissions-predictability

Regularities in our surroundings lead to predictions about upcoming events. Previous research has shown, that omitted sounds during otherwise regular tone sequences elicit frequency-specific neural activity related to the upcoming but omitted tone. We tested whether this neural response is depending on the unpredictability of the omission. Therefore we recorded MEG data while participants listened to ordered or random tone sequences with omissions occurring either ordered or randomly. Using multivariate pattern analysis shows that the frequency-specific neural pattern during omission within ordered tone sequences occurs independent of the regularity of the omissions suggesting that the auditory predictions based on sensory experiences are not immediately updated by violations of those expectations. ### Competing Interest Statement The authors have declared no competing interest.
