Which hemisphere of the brain is predominantly associated with language processing?

The left hemisphere of the brain is predominantly associated with language processing due to its specialization in managing linguistic tasks, including speech production, comprehension, reading, and writing. This lateralization is supported by a significant body of research, including studies on patients with brain lesions and functional imaging techniques, which demonstrate that areas such as Broca's area and Wernicke's area—both crucial for language function—are typically located in the left hemisphere.

Broca's area, situated in the frontal lobe, is responsible for speech production, while Wernicke's area, located in the temporal lobe, is involved in understanding spoken and written language. This specific organization allows for efficient processing and integration of language skills. While the right hemisphere does contribute to some aspects of language, such as emotional tone and prosody, its role is not as central as that of the left hemisphere.
