The P300 Auditory Evoked Potential in Cochlear Implant Users: A Scoping Review.

 The P300 auditory evoked potential is a long-latency cortical potential evoked with auditory stimulation, which provides information on neural mechanisms underlying the central auditory processing.  To identify and gather scientific evidence regarding the P300 in adult cochlear implant (CI) users.  A total of 87 articles, 20 of which were selected for this study, were identified and exported to the Rayyan search software.

Behavioral and Electrophysiological Assessment of Adults Who Underwent Cochlear Implantation After Hearing Aid Experience.

 Cochlear implantation has been considered a viable option to restore hearing perception in adults with severe to profound postlingual hearing loss.  To analyze behavioral hearing responses and P300 latency and amplitude measurements in adults with bilateral sensorineural hearing loss at two phases, first when they were using hearing aids (HAs) and, then, after 12 months of cochlear implant (CI) use. The association between behavioral and electrophysiological evaluations was explored, as it is believed that the study of auditory processing with different hearing devices can contribute to future CI adjustments and fittings, especially for patients who cannot give subjective feedback (such as small children and individuals with multiple disabilities).
