Really? The Brain Gets Rewired if One of the Senses Is Lost By ANAHAD O'CONNORTHE FACTS
Certain regions of the human brain are dedicated to the various senses. The visual cortex handles vision, for example, while the auditory cortex processes sound.
But what happens if one of the senses is lost? Do the neurons in the auditory cortex of a deaf person atrophy and go to waste, for instance, or are they put to work processing vision and other senses?
In studies, scientists have shown that when one sense is lost, the corresponding brain region can be recruited for other tasks. Researchers learned this primarily by studying the blind. Brain imaging studies have found that blind subjects can locate sounds using both the auditory cortex and the occipital lobe, the brain's visual processing center.
But recently a similar phenomenon was discovered in the deaf. In a study financed by…
