Abstract In children, intracranial responses to auditory detection and discrimination processes have not been reported. We, therefore, recorded intracranial event-related potentials (ERPs) to both standard and deviant tones and/or syllables in 4 children undergoing pre-surgical evaluation for epilepsy. ERPs to detection (mean latency = 63 ms) and discrimination (mean latency = 334 ms) were highly localized to areas surrounding the Sylvian fissure (SF). These potentials reflect activation of different neuronal populations and are suggested to contribute to the scalp recorded auditory N1 and mismatch negativity (MMN).
