| Effects of Cochlear Implantation on Cortical Development and Cross-Modal Cortical Re-Organization in Children with Single-Sided Deafness
Effects of Cochlear Implantation on Cortical Development and Cross-Modal Cortical Re-Organization in Children with Single-Sided Deafness
Single-sided deafness (SSD) refers to normal hearing in one ear and a severe-profound sensorineural hearing loss in the contralateral ear. The prevalence of SSD is estimated to affect 3-6% of the population with increased incidence among children. SSD is linked to impairments in auditory sound localization and speech perception in background noise. Children with SSD are also at increased risk for delays in speech and language development and educational progress, and SSD has been linked to negative affects on social-emotional well-being and health-related quality of life. Cochlear implantation is expanding as a potential treatment option for SSD. The purpose of this study is to examine the effects of cochlear implantation (CI) on cortical development and cross-modal re-organization before and after cochlear implantation in pediatric cases of SSD using cortical auditory, visual, and somatosensory evoked potential paradigms (CAEPs, CVEPs, CSSEPs) via high-density EEG. Behavioral correlates of speech perception in background noise were also measured. Further research in this area may be useful in evaluating the efficacy of CI in SSD and predicting behavioral outcomes after intervention.
- Participants will be able to describe the current status of cochlear implantation as a treatment option for pediatric single-sided deafness.
- Participants will be able to describe cortical brain organization in case studies of patients with single-sided deafness before cochlear implantation.
- Participants will be able to describe how cochlear implantation affects cortical brain organization and impacts behavioral function in pediatric cases of single-sided deafness.

Presenters/Authors
Hannah Glick
(), University of Colorado Boulder, hannah.glick@colorado.edu;
Hannah is a licensed audiologist and combined Ph.D. candidate in Speech, Langauge, & Hearing Science; Behavioral Neuroscience; and Cognitive Science at the University of Colorado-Boulder (CU-Boulder). She is the laboratory of the Brain & Behavior Laboratory under principal investigation of Dr. Anu Sharma at CU-Boulder. With a broad interest in hearing loss-related brain changes across the age spectrum, she hopes to combine her clinical and research skills in the changing landscape of audiology and neuroscience. Her special interests include brain changes in age-related hearing loss, cross-modal cortical plasticity, and cochlear implants.
