| Title | Cortical Processing of Vocal and Nonvocal Sounds in Cochlear-Implanted Children: An Electrophysiological Study |

| Summary, etc | Objectives: For prelingually deaf children, cochlear implants (CIs) can<br/>restore auditory input to the auditory cortex and the ability to acquire<br/>spoken language. Language development is strongly intertwined with<br/>voice perception. The aim of this electrophysiological study was to<br/>investigate human voice processing using measures of cortical auditory<br/>evoked potentials (AEPs) in pediatric CI users.<br/>Design: Cortical AEPs were measured in 8 CI children (4 to 12 years old)<br/>with good auditory and language performance and 8 normal-hearing<br/>(NH) age-matched controls. The auditory stimuli were nonspeech vocal<br/>sounds (laughing, sighing, coughing) and environmental sounds (e.g.,<br/>telephones, alarms, cars, bells, water, wind). Independent component<br/>analysis was used to minimize the CI artifact in cortical AEPs.<br/>Results: Fronto-temporal positivity to vocal sounds was found in NH<br/>children, with a significant effect in the 140 to 240 msec latency range.<br/>In CI children, there was a positive response to vocal sounds in the 170<br/>to 250 msec latency range, with a more diffuse and anterior distribution<br/>than in the NH children.<br/>Conclusions: Cortical responses to vocal sounds were recorded in CI<br/>children. The topography and latency of response to voice differed from<br/>that of NH children. The results suggest that cortical reorganization for<br/>processing vocal sounds may occur in congenitally deaf children fitted<br/>with a CI. |
