BACIC Project | What to expect as a participant in this study
Brain Activation of Cochlear Implant Candidates (BACIC) Project researchers aim to identify brain-based factors that predict future hearing improvements among candidates for cochlear implants. In the future, this knowledge will help guide clinical practices and empower individuals seeking solutions for severe to profound hearing loss.
Although cochlear implants can significantly improve auditory speech perception in individuals with severe to profound hearing loss, the procedure’s success rate is difficult to predict.
Certain factors in the brain may contribute to the large unexplained variance in individuals’ abilities to hear and understand spoken language after getting CI(s).
Nebraska’s innovative brain imaging research may shed light on brain-based factors, particularly those driven by brain plasticity, that contribute to why some adults with CI have better outcomes than others.

[00:00:08.730]Hello and welcome to the BACIC project.
[00:00:11.830]BACIC stands for brain activation
[00:00:13.950]of cochlear implant candidates.
[00:00:15.800]In this study Nebraska researchers aim to identify
[00:00:19.140]the brain based factors that predict
[00:00:21.360]future hearing improvements among candidates
[00:00:23.830]for cochlear implants.
[00:00:25.430]we use magnetic resonance imaging,
[00:00:27.430]or MRI scanners to produce detailed images of the brain.
[00:00:31.430]These images help us understand why some adults
[00:00:34.020]with cochlear implants have better results than others.
[00:00:37.159]In this short video,
[00:00:39.260]we'll outline what to expect as a participant in this study.
[00:00:44.230]During this study,
[00:00:45.380]you will be making three separate visits to
[00:00:47.510]the Center for Brain Biology and Behavior,
[00:00:50.150]or CB3 for short.
[00:00:52.090]CB3 is located in the Southeast corner of Memorial Stadium
[00:00:55.970]at the University of Nebraska Lincoln.
[00:00:58.130]Free parking is available for study participants in the lot
[00:01:01.080]directly east of the stadium.
[00:01:02.960]Just look for the white signs that say
[00:01:04.810]east stadium research labs.
[00:01:06.880]From there head to the Southeast corner of the stadium,
[00:01:09.700]and look for the CB3 entrance.
[00:01:12.055]Enter the lobby area and check in with Linda
[00:01:15.010]at the front desk.
[00:01:16.376]To validate your parking,
[00:01:18.380]Linda will ask for the make model
[00:01:20.340]and license plate number of your vehicle.
[00:01:22.400]So be sure to have that information available.
[00:01:24.856]Next, a researcher will greet you
[00:01:27.150]and bring you to the MRI suite.
[00:01:31.810]Since the scanner uses magnets,
[00:01:33.870]nothing metal can be taken into the suite.
[00:01:36.590]This includes things like jewelry, piercings, belts, keys,
[00:01:40.820]cell phones, and coins.
[00:01:42.920]Prior to entering you will fill out a metal screening form
[00:01:45.920]to be sure you don't have anything metal on or in your body.
[00:01:49.710]A locker is available to safely store
[00:01:51.960]any belongings that cannot enter the suite.
[00:01:55.650]After you complete your metal screening form,
[00:01:58.750]a researcher will explain the project to you together,
[00:02:01.400]and you will go through the informed consent form.
[00:02:04.501]When all of your questions are answered
[00:02:06.600]and you have signed the informed consent
[00:02:08.680]our MRI technician will take some pictures of your brain
[00:02:11.640]using an MRI scanner.
[00:02:13.500]You can't feel an MRI scan.
[00:02:15.870]The machines do not move or spin you around,
[00:02:18.470]but the machine is loud.
[00:02:20.890]We will provide ear protection and we will be communicating
[00:02:23.699]with you to ensure you're comfortable
[00:02:26.020]throughout the whole session.
[00:02:28.441]During your scan we ask that you remain perfectly still.
[00:02:32.360]This will make sure that the images do not blur.
[00:02:36.780]After we wrap up your MRI session,
[00:02:39.300]we will walk you to another area
[00:02:41.260]to look at your brain activity,
[00:02:42.810]using functional near infrared spectroscopy or fNIRS.
[00:02:47.280]This involves wearing a special head cap
[00:02:50.534]covered in sensors that highlight your brain activity
[00:02:52.630]and detect brain activations during specific tasks.
[00:02:57.098]After the fNIR scan,
[00:02:59.359]we will ask you to fill out some forms
[00:03:01.420]regarding your hearing, executive functions,
[00:03:04.040]and some demographic information.
[00:03:06.300]This will conclude your first visit.
[00:03:10.100]Your second and third visits will be the same as your first,
[00:03:13.200]except there will be no MRI session.
[00:03:16.350]You will only need to do that part once.
[00:03:19.310]We appreciate you taking the time to assist us
[00:03:21.660]with the BACIC project
[00:03:22.820]and look forward to analyzing the results.
