Auditory event-related potentials reflect dedicated change detection activity for higher-order acoustic transitions

► Auditory change-detection relies in part on dedicated change-detector structures. ► Their activity is reflected by transient event-related potentials (ERPs). ► Previously, the N1 of the ERP was found to first-order but not higher-order changes. ► We show that high-speed frequency glide-to-constant transitions elicit N1. ► Therefore, dedicated change detectors also exist for higher-order changes.
