Assessing the Relationship Between Pitch Perception and Neural Health in Cochlear Implant Users

alexandrossfakianakis shared this article with you from Inoreader Assessing the Relationship Between Pitch Perception and Neural Health in Cochlear Implant Users via JARO - Journal of the Association for Research in Otolaryngology via MedWorm.com This study investigated whether the neural health estimates have stronger correlations with the temporal and place pitch sensitivity than with the speech recognition performance. On five electrodes in 12 tested ears of eight adult CI users, polarity effect (PE), multipulse integration (MPI), and interphase gap (IPG) effect on the amplitude growth function (AGF) of electrically evoked compound action potential (ECAP) were measured to estimate neural health, while thresholds of amplitude modulation frequency ranking (AMFR) and virtual channel ranking (VCR) were measured to indicate temporal and place pitch sensitivity. AzBio sentence recognition in noise was measured using the clinical CI processor for each ear. The results showed significantly poorer AMFR and VCR thresholds on the basal ele... View on Web
