Relationships between event-related potentials and intracranial responses to auditory target detection: Brief report

Simultaneous scalp ERPs and intracranial frontal and intracranial temporal ERP-like responses were obtained from nine temporal lobe epilepsy patients. Deep frontal, but not temporal, waveforms were consistent across sites, hemispheres, and subjects. Consistent latency and polarity relationships were also seen between scalp and frontal intracranial waveforms. A component of the same polarity and latency as the surface N1 appeared in all deep …
