Wernicke's area is a functionally defined structure that is involved in language comprehension.
Wernicke's area is a functionally defined structure that is involved in language comprehension. In about 97% of humans (including a large majority of left–handers) major language functions are contained in the left hemisphere of the brain and for most people, Wernicke's area is lateralized to the left side. It takes its name from Carl Wernicke, who worked with language-impaired patients to distinguish separate regions for language comprehension from production.
