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. Language processing has been linked to Broca's area since Pierre Paul Broca ...

Cytoarchitecturally the opercular part of the inferior frontal gyrus is known as Brodmann area 44 (BA44). The triangular part of the inferior frontal gyrus is known as Brodmann area 45 (BA45), and the orbital part of the inferior frontal gyrus is known as Brodmann area 47. The opercular part and the triangular part (BA44 and BA45) make up Broca ...
The angular gyrus is represented in orange, the supramarginal gyrus is represented in yellow, Broca's area in blue, Wernicke's area in green, and the primary auditory cortex in pink. In neuroscience and psychology , the term language center refers collectively to the areas of the brain which serve a particular function for speech processing and ...
Many researchers now include BA45 in the prefrontal cortex because together with BA44 it makes up an area of the frontal lobe called Broca's area. [20] Broca's Area is widely considered the output area of the language production pathway in the brain (as opposed to Wernicke's area in the medial temporal lobe, which is seen as the language input ...
Damage to the dominant hemisphere (usually the left hemisphere) results in aphasia (i.e. Broca's area or Wernicke's) Damage to the non-dominant hemisphere (usually the right hemisphere) results in contralateral neglect syndrome, inaccurate localization in the half field, impaired ability to judge distance (nondominant parietal lobe).
In neuroanatomy, the arcuate fasciculus (AF; from Latin 'curved bundle') is a bundle of axons that generally connects Broca's area and Wernicke's area in the brain. It is an association fiber tract connecting caudal temporal lobe and inferior frontal lobe. [1]
The planum temporale is a brain region within Broca's Area, and is thought to be the most asymmetric area of the human brain; with the left side having shown to be five times the size of the right in some individuals. [9] However in people who are left handed, this asymmetry has shown to be reduced [10]
