Blind People Really Do Have More Sensitive Hearing, MRI Study Finds
The authors behind this latest study, published in the Journal of Neuroscience, say theirs is one of the first to look at what’s happening in the auditory cortex of people living with blindness. They scanned the auditory cortexes of people who were born blind or developed blindness early in life (including some people with anophthalmia, a condition where the eyes are completely absent) via MRI. In those who were blind, the auditory cortex appeared to be more attuned to frequencies of sound played in the test, based on the kinds of brain activity the researchers saw in the scans.
