As a result of receiving cochlear implants, children begin to develop new pathways for processing auditory and complementary visual information. We are studying brain activity using non-invasive methods to learn how a cochlear implant influences language and cognitive ability, particularly among children who are developing spoken English and ASL.
Recording the brain activity of children while they are listening to sounds and watching images can reveal insights about how children adapt to and process aural stimulation and develop listening capability. We follow some children year after year to investigate developmental changes that take place as they grow and mature. Participating children wear a soft, stretchy swimming cap with sensors that passively detect their brain activity, while they play with toys and interactive video games, or watch cartoons, accompanied by their parents.
