Adults 18 to 65 Years Old with Cochlear Implants Needed for Research Study

What is the purpose of this study?

The purpose of this research study is to improve EEG techniques for those who have a cochlear implant and examine how the brain responds to sensory stimuli such as sounds or pictures.

An EEG is a test that measures and records the electrical activity of the brain (or “brainwaves”).

Who can participate?

Adults 18 to 65 years old who have cochlear implants and are not currently taking medication for a neurologic condition may be eligible to participate.

What is involved?

You will be in the research study for about 2 hours and have 1 study visit.

During your study visit, you will take part in an EEG test. Tiny disk electrodes will be placed on top of your scalp and will record brainwave activity in response to sounds or images you see or hear while watching a computer screen.

Depending on the task, you may be required to actively respond by pressing a button or verbal responding to sounds or images. Other tasks will not require any active participation. In those cases, you may sleep, read, play games on a handheld device or watch a closed-captioned movie of your choice.

What are the benefits?

You will not receive a direct medical benefit. However, the information gained from this study may help our understanding of language development and language and attention disorders in people with a cochlear implant in the future.

Will I get all the facts about the study?

As someone interested in participating, you will be given a consent form that thoroughly explains all of the details of the study. The form covers all of the procedures, the risks, the benefits, the pay, who to contact with questions or concerns and more. A member of the study staff will review the consent form with you and will be sure that all of your questions are answered.

What are the risks and discomforts of the study?

There are no known risks to EEG testing, however some people find that wearing an EEG cap for extended periods of time may be uncomfortable. Should that be the case, the EEG cap will be re-positioned, or exchanged for a more comfortable one. There may be unknown or unforeseen risks associated with study participation.

A detailed list of possible risks or discomforts will be provided to you if you are interested in knowing more about this study.

Do participants receive pay, compensation or reimbursement?

Participants will receive $50 for their time and travel.
