WDEL's Delaware HealthWatch

Deaf Brains

New research deaf people's brains process information differently than the brains of people who can hear. Details coming up in WDEL's Delaware Healthwatch.

The brain's auditory cortex processes sound and contributes to most people's ability to hear, but profoundly deaf people's auditory cortexes are not exposed to auditory stimuli, so what's happening there? That's the focus of a new study by the National Institutes of Health. Here's NIH's Doctor Christina Karns.

"The reason that we want to know the answer to this question is, it tells us something about how the brain develops."

NIH recently conducted a study examining activity in the auditory cortexes of hearing and deaf people.

"And what we found was that in deaf participants, Heschl's gyrus, which is primary auditory cortex, had a much stronger response to touch and vision than in the hearing participants."
