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 ...
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 .
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 ...
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 ...
Expressive aphasia (also known as Broca's aphasia) is a type of aphasia characterized by partial loss of the ability to produce language (spoken, manual, [1] or written), although comprehension generally remains intact. [2]
The most common stroke that causes Wernicke's Aphasia is an ischemic stroke affecting the posterior temporal lobe of the dominant hemisphere of the brain. [14] "The middle cerebral arteries supply blood to the cortical areas involved in speech, language and swallowing.
Broca's, Wernicke's, and the arcuate fasiculus are left intact; however, they are isolated from other brain regions. [2] A stroke is one of the leading causes of disability in the United States. [3] Following a stroke, 40% of stroke patients are left with moderate functional impairment and 15% to 30% have a severe disability as a result of a ...
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.
