Broca’s Area

Definition:

Broca’s Area, named after the French physician Pierre Paul Broca, is a region of the frontal lobe located in the dominant hemisphere of the brain, typically in the left hemisphere for about 95% of right-handed individuals and 70% of left-handed individuals. It is involved in the production and comprehension of language.

Function:

Broca’s Area plays a crucial role in language production, including speech formation and articulation. It is primarily responsible for coordinating the muscles involved in speech production and generating the motor commands necessary for fluent verbal communication.

Location:

Broca’s Area is located in the posterior part of the frontal lobe, usually in the left hemisphere of the brain. It is situated in the frontal cortex, specifically in the posterior inferior frontal gyrus, adjacent to the lateral sulcus, also known as the Sylvian fissure.

Broca’s Aphasia:

Damage to Broca’s Area can result in a language disorder called Broca’s Aphasia. Individuals with Broca’s Aphasia have difficulty with speech production and struggle to form words and sentences. Although their comprehension of language remains relatively intact, their ability to express themselves is severely impaired.
