NIH study shows the deaf brain processes touch differently – 3
Narrator: This is NIH Health Matters, I’m Joe Balintfy. Researchers have learned that vision and touch together are processed differently in deaf people.
Karns: We scanned the brain of hearing people and people born profoundly deaf while they did a task.
Narrator: Dr. Christina Karns is an NIH postdoctoral research associate.
Karns: 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.
Narrator: This research adds to a growing list of discoveries that confirm the impact of experiences and outside influences in molding the developing brain. For details, visit www.nidcd.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
