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 ...
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 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 ...
Carl (or Karl) [a] Wernicke (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]; 15 May 1848 – 15 June 1905) was a German physician, anatomist, psychiatrist and neuropathologist.He is known for his influential research into the pathological effects of specific forms of encephalopathy and also the study of receptive aphasia, both of which are commonly associated with Wernicke's name and ...
The belt is the area immediately surrounding the core; the parabelt is adjacent to the lateral side of the belt. [6] Besides receiving input from the ears via lower parts of the auditory system, it also transmits signals back to these areas and is interconnected with other parts of the cerebral cortex.
Wernicke's area, which spans the region between temporal and parietal lobes of the dominant cerebral hemisphere (the left, in the majority of cases), plays a key role (in tandem with Broca's area in the frontal lobe) in language comprehension, [13] whether spoken language or signed language.
Damage to this area would result in Broca aphasia which causes the patient to become unable to formulate coherent appropriate sentences. [17] 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.
Therefore, when Broca's area or surrounding areas in the left hemisphere are damaged, hemiplegia or hemiparesis often occurs on the right side of the body in individuals with Broca's aphasia. Severity of expressive aphasia varies among patients. Some people may only have mild deficits and detecting problems with their language may be difficult.
