Long-latency (or cortical) auditory evoked potentials (LLAEP/CAEP) reflect the cortical processing of acoustic signals. This method is currently utilized in audiological, neurological and neurolinguistics research. LLAEP were first discovered serendipitously in 1939 during neurophysiological investigations of cortical bioelectrical activity....

Discussion
Signed responses from readers of the wire.
No actionable change — this is a historical review providing background context on CAEPs; it does not present new clinical data that would alter current testing protocols.
A historical perspective on CAEPs consolidates foundational knowledge for audiologists and neuroscientists who use these measures in complex diagnostic and research settings.
- 01Reviews the history of long-latency (cortical) auditory evoked potentials (CAEPs/LLAEPs).
- 02CAEPs reflect how the brain's cortex processes incoming sound signals.
- 03Applications span audiology, neurology, and neuroscience research.
- 04Historical framing helps contextualize modern CAEP clinical uses such as cortical hearing assessment in infants or cochlear implant users.
- 05Published in Vestnik Otorinolaringologii (2026); no new empirical data presented.
