Researchers have been able to solve a long standing mystery about the deaf and their extraordinary vision.

Scientists have been able to establish the reason why some deaf people tend to have a superior peripheral vision. In a study done on deaf cats (as their brains are organized just like humans’), they found that the brain regions usually responsible for hearing get ‘co-opted’ to the visual system, thus augmenting the vision. However, the deaf cats didn’t have better overall vision; instead they were found to have greater peripheral vision and motion detection, which perhaps explains why deaf people are able to assess their surroundings much more accurately.
