NIH study shows the deaf brain processes touch differently – 4
Narrator: This is NIH Health Matters, I’m Joe Balintfy. Researchers have been able to show that deaf people use their auditory cortex to process touch and vision to a much greater degree than occurs in hearing people. Dr. Christina Karns an NIH postdoctoral researcher says in a recent study, hearing participants’ auditory cortex specialized for hearing.
Karns: But in the deaf people the brain has reorganized or organized in a way that’s not typical so that they're responding to these other senses. And in fact the response to touch was about twice as strong as for vision.
