How a Deaf Brain Is Rewired to Boost Vision

A brain is a terrible thing to waste--and your brain knows that. A new study of congenitally deaf cats has shown that some parts of their brains which would typically work on hearing are repurposed, and instead help out with vision. As a result of that clever efficiency, these deaf cats have superior peripheral vision and motion-detection abilities than cats with normal hearing. Researchers say the human brain may perform the same trick.
