Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production.
Broca area, region of the brain that contains neurons involved in speech function. This area, located in the frontal part of the left hemisphere of the brain, was discovered in 1861 by French surgeon Paul Broca, who found that it serves a vital role in the generation of articulate speech.
Broca's area, crucial for language production and speech control, is primarily associated with Brodmann Area 44 and 45, located in the left hemisphere's frontal lobe. These regions play a central role in speech generation, language processing, and syntactical aspects of communication.
The French physician and anatomist, Pierre Paul Broca, may have discovered the most crucial part when he identified a common region in the brain in two of his speech-impaired patients; this came to be known as the Broca (Broca's) area.
Broca's area is a region of the brain in in the frontal lobe that is associated with language production and comprehension. Learn how to keep Broca's area healthy.
Our nervous system has two dedicated areas that allow us to communicate. The production of speech takes place in Broca’s area located in the frontal lobe. However, the interpretation of speech happens elsewhere. Wernicke’s area – located in the temporal lobe – processes what is being spoken.
Broca’s area is located in the inferior (lower) posterior (back) section of the frontal lobe, quite close to the speech centers and the auditory canal. It houses specialized cell types grouped into two Brodmann areas – 44 and 45.
Theories of human cognition prominently feature Broca’s area, which causally contributes to a myriad of mental functions. However, Broca’s area is not a monolithic, multi-purpose unit; it is structurally and functionally heterogeneous.
The Broca area is located in the inferior frontal gyrus, the part of the brain known as the motor speech area. The area is responsible for speech production, including regulating breathing while speaking and vocalizing. It’s also linked to language processing and comprehension.
Broca's area, named after pathologist Paul Broca (1824–1880), lies in the posterior inferior frontal gyrus (Dronkers et al., 2007). Damage to this area can cause non-fluent aphasia, under which patients retain speech comprehension but experience dysprosody and agrammatism during speech production ( Acharya & Wroten 2021 ).
