The human brain structure can be affected by changes in a person's native language. Linguistic experience can shape the brain's structure, neural connections, and functions.

Left hemisphere's Broca's and Wernicke's areas, are more developed in bilingual individuals than in monolingual individuals.  

Research has also revealed that the language we speak can affect the way we think and perceive the world.  

The brain can adapt and reorganize its structure to accommodate changes in language use. This is known as neuroplasticity and is essential for learning and memory processes.

Studies have shown that children who learn multiple languages at a young age have denser gray matter in brain regions associated with language processing than monolingual children.

learning a second language later in life can also have beneficial effects on the brain, including increased gray matter density in language regions and improved cognitive functions. 

The structure of the brain can vary between individuals based on their native language.  tonal language can influence the development of the auditory cortex differently than non-tonal languages.  

Studies have shown that the brain regions involved in visual processing and motor control are more developed in sign language users than in non-signers.
