Broca
Broca's Area
Broca's Area (pronounced: /ˈbroʊkəz ˈɛəriə/) is a region in the frontal lobe of the brain that is associated with language processing.
Etymology
The term "Broca's Area" is named after Paul Broca, a French physician, anatomist, and anthropologist, who discovered this area of the brain during the 19th century. He found that damage to this area resulted in speech and language deficits, a condition now known as Broca's aphasia.
Function
Broca's Area is involved in various language and speech functions. It is responsible for the production of speech, language comprehension, and also plays a role in language processing and understanding. It is connected to Wernicke's area through a bundle of nerve fibers called the arcuate fasciculus.

- Wernicke's Area: Another crucial area for language processing, located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left hemisphere in about 95% of right-handed individuals and 70% of left-handed individuals.
- Arcuate Fasciculus: A bundle of axons that forms part of the superior longitudinal fasciculus, connecting Broca's area and Wernicke's area.
