Objective measures of Cochlear Implant (CI) outcome as assessed by a synergistic use of combined Electroencephalography (EEG) and Positron Emission Tomography (PET)

Introduction (background / research question) Despite decades of optimization, understanding speech with cochlear implants (CIs) remains variable, especially in complex listening scenarios. Combining electroencephalography (EEG) and positron emission tomography (PET) with O-15 water enables an objective study of neural correlates of speech perception, leveraging the high spatial resolution of the PET and the high temporal resolution of the EEG.
