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 ...
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 ...
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 .
The sensory speech region, Wernicke’s area, and the motor speech region, Broca’s area, are interconnected by a large axonal fiber system known as the arcuate fasciculus which passes directly beneath the insular cortex. On account of this anatomical architecture, ischemic strokes in the insular region can disrupt the arcuate fasciculus. [15]
Broca's area is located in the left hemisphere prefrontal cortex above the cingulate gyrus in the third frontal convolution. [16] Broca's area was discovered by Paul Broca in 1865. This area handles speech production. Damage to this area would result in Broca aphasia which causes the patient to become unable to formulate coherent appropriate ...
The superior temporal gyrus also includes Wernicke's area, which (in most people) is located in the left hemisphere. It is the major area involved in the comprehension of language. The superior temporal gyrus is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition.
Most language processing takes place in Broca's area usually in the left hemisphere. [9] Damage to this region often results in a type of non-fluent aphasia known as Broca's aphasia. Broca's area is made up of the pars opercularis and the pars triangularis, both of which contribute to verbal fluency, but each has its own specific contribution.
