Association between cortical auditory evoked potentials recorded directly through cochlear implants and post-implantation auditory and speech outcomes

These findings provide near-field neurophysiological evidence supporting the critical role of sensitive periods in auditory cortical development. The results underscore the value of intracochlear eCAEPs as a neuroscience-based, objective biomarker of auditory cortical function and plasticity in CI users. This approach enables real-time monitoring of neuroplastic changes and offers a novel platform for translational auditory neuroscience in both pediatric and adult implant recipients.
