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. [1]
Wernicke's area contributes to phonological retrieval. [7] All speech production tasks (e.g. word retrieval, repetition, and reading aloud) require phonological retrieval. The phonological retrieval system involved in speech repetition is the auditory phoneme perception system, and the visual letter perception system is the one that serves for ...
Although Wernicke's area (left posterior superior temporal cortex) is known as the language comprehension area of the brain, defining the exact region of the brain is a more complicated issue. A 2016 study aimed to determine the reliability of current brain models of the language center of the brain.
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. [2] [3]
Wernicke encephalopathy (WE), also Wernicke's encephalopathy, [1] or wet brain is the presence of neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine (vitamin B 1). [2]
Wernicke's Area Wernicke's area was discovered in 1976 by Carl Wernicke and was found to be the site of language comprehension. Wernicke's area is also found in the left hemisphere in the temporal lobe. Damage to this area of the brain results in the individual losing the ability to understand language.
The model is known as the Wernicke–Geschwind model. For listening to and understanding spoken words, the sounds of the words are sent through the auditory pathways to area 41, which is the primary auditory cortex (Heschl's gyrus). From there, they continue to Wernicke's area, where the meaning of the words is extracted.
