Abstract

Responses to infrequently exchanging two segments of a complex tonal pattern were tested for the presence of the mismatch negativity event-related brain potential com-ponent. This component is elicited when an auditory stimulus differs from the sensory memory trace of the pre-viously presented repetitive sound. Because the segments exchanged in the tonal pattern differed from each other only in their durations, the elicitation of the mismatch res-ponse revealed that the temporal structure of sound pat-terns is encoded in the traces underlying the mismatch process. Results showing that the mismatch response was elicited even when the tonal patterns were presented con-tinuously (i.e. without silent intervals separating successive patterns) demonstrate the automatic detection of periodicity in the acoustic stream.
