Read our privacy policy Blind people's brains rewire themselves to allow them to track moving objects by sound, a study has found. “For a sighted person, having an accurate representation of sound isn’t as important because they have sight to help them recognise objects, while blind individuals only have auditory information,” said Kelly Chang, one of the study's authors from the University of Washington. “This gives us an idea of what changes in the brain explain why blind people are better at picking out and identifying sounds in the environment.” The findings are published in two papers. One study in the Journal of Neuroscience used MRIs to scan the brain activity of blind subjects and test how finely tuned their neurons were to subtle changes in frequency.
