Previous studies have shown that the functional areas of the brain are not static. Researchers use functional magnetic resonance imaging to scan the visual area of the brain when a congenital blind performs a sentence understanding task. If the visual cortex of the brain has language processing capabilities, then When exposed to linguistic information, it will show the same sensitivity as the classical brain language area. It was found that the brain visual area is sensitive to sentence structure and word meaning performance. Researchers believe that the visual cortex of innately blind people can process language. ['Studies show that congenitally blind people are active in the left visual cortex when performing tasks that read Braille.', 'Under the condition that the language center plays a normal function, the visual cortex of the congenital blind will compete with other functions because it has not obtained visual functions.', 'If surgery is performed early in human life, such as connecting its nerves to the visual cortex of the brain, the visual cortex will process sound information.', 'Different parts of the human visual cortex acquire different functions during development, and part of the left visual area acquires language processing functions.']
