Title: Specific Aims Presentation: Reliable measures of functional cortical processing of speech in adult cochlear-implant recipients
Abstract: Cochlear implants (CIs) have the potential to provide excellent speech-recognition ability to individuals with hearing loss. This potential, however, is not realized in every CI recipient; some individuals receive significant benefits in their speech-recognition ability, while others only receive minimal benefit. Collectively, only 10-20% of the variance in speech-recognition ability is accounted for by known factors. A lesser-studied factor that could substantially impact CI outcomes is the cortical activation patterns elicited by speech following implantation. The gap in knowledge is that how and where naturalistic auditory speech is processed in the brain in CI recipients and its impact on speech-recognition performance is largely unknown, which represents a significant barrier toward the understanding of individual variability in CI outcomes. The goal of this project is to investigate auditory-evoked cortical activity in adults with CIs and its relationship to speech-recognition scores. The first aim will pilot new methodologies to maximize the within-subject reliability of fNIRS measures in a normal-hearing group. The second aim will investigate the relationship between auditory-evoked activity in the brain and speech-recognition scores using naturalistic, pseudo-connected speech stimuli that mimics everyday listening. Results will provide a critical understanding of the relationship between speech-recognition ability and functional cortical auditory processing in adult CI recipients.
