About this trial

The study will help us in understanding the neural mechanisms by which listeners with a cochlear implant detect speech in noisy environments.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Between 18 and 99 years of age.

Have a cochlear implant activated for more than one year.

Eligible for research under the Iowa Cochlear Implant Project VIII.

Ability to understand and willingness to sign a written informed consent document.

Disqualifiers

Medical history includes seizure disorder, head injury, neurologic, metabolic, cardiovascular disease, or previous cerebrovascular event (unless approved by PI).

Female self-reporting pregnancy. A urine pregnancy test will be performed prior to injection of the radiopharmaceutical.

Currently taking medications which may affect cerebral blood flow (e.g., papaverine, ginkgo biloba, acetazolamide).

Uncontrolled intercurrent illness that would limit compliance with study requirements per investigator.

To identify the cortical bases for speech-in-noise understanding in cochlear implant users

PET imaging will be used to identify the brain regions for listeners ability to recognize speech in noise at different signal-to-noise ratios.
