O15-PET Imaging of Cochlear Implant Speech in Noise Processing
Phillip Gander
Summary
The study will help us in understanding the neural mechanisms by which listeners with a cochlear implant detect speech in noisy environments.
Description
Despite the success of a cochlear implant (CI) for providing or improving hearing ability for people with severe hearing loss, everyday conversations in background noise are still the main clinical complaint. The goal of this study is to understand the neural mechanisms by which listeners with a CI detect speech in noisy environments, and to understand how these mechanisms differ across a variety of CI listeners, in order to determine what variables are most relevant for predicting successful outcome. Therefore the purpose of PET neuroimaging in this study is to find the brain regions that rel…
