Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...
From there, they continue to Wernicke's area, where the meaning of the words is extracted. In order to speak, the meanings of words are sent from Wernicke's area via the arcuate fasciculus to Broca's area, where morphemes are assembled. The model proposes that Broca's area holds a representation for articulating words.
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 middle cerebral arteries supply blood to the cortical areas involved in speech, language and swallowing. The left middle cerebral artery provides Broca's area, Wernicke's area, Heschl's gyrus, and the angular gyrus with blood". [20] Therefore, in patients with Wernicke's aphasia, there is typically an occlusion to the left middle cerebral ...
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]
Two areas of the brain, Broca's area and Wernicke's area, are responsible for various disruptions in speech when damaged. Each is defined by their distinct characteristics. Broca's aphasia is characterized by non-fluent or telegraphic-type speech - where articles, conjunctions, prepositions, auxiliary verbs, pronouns and morphological ...
The discoveries of Paul Broca were made during the same period of time as the German Neurologist Carl Wernicke, who was also studying brains of aphasiacs post-mortem and identified the region now known as Wernicke's area. Discoveries of both men contributed to the concept of localization, which states that specific brain functions are all ...
Wernicke's research into the fiber pathways connecting the posterior and anterior regions lead him to theorize that damage to the fibers under the insula would lead to conduction aphasia. Ludwig Lichtheim expanded on Wernicke's work, although he labeled the disorder commissural aphasia, to distinguish between aphasias tied to processing centers ...
