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 ...
Carl Wernicke was an influential nineteenth century neuropsychiatrist specifically interested in understanding how abnormalities could be localized to specific brain regions. Previously held theories attributed brain function as one singular process but Wernicke was one of the first to attribute brain function to different regions of the brain ...
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.
The best example of an established lateralization is that of Broca's and Wernicke's areas, where both are often found exclusively on the left hemisphere. Function lateralization, such as semantics , intonation , accentuation , and prosody , has since been called into question and largely been found to have a neuronal basis in both hemispheres ...
Freud was skeptical of Wernicke's findings, citing a paucity of clinical observation as his reason. Although he conceded the fact that language is linked to neurological processes, Freud repudiated a model of localization of brain function, according to which specific regions of the brain are responsible for certain cognitive functions. In ...
While descriptions of behavioral syndromes go back to the ancient Greeks and Egyptians, it was during the 19th century that behavioral neurology began to arise, first with the primitive localization theories of Franz Gall, followed in the mid 19th century by the first localizations in aphasias by Paul Broca and then Carl Wernicke.
In 1874 Carl Wernicke also made a similar observation in a case study involving a patient with a brain lesion whom was unable to comprehend speech, the part of the brain with the lesion is now deemed Wernicke's Area. [6] Both Broca and Wernicke believed and studied the theory of localization. [6]
Wernicke's aphasia, also known as receptive aphasia, is a language disorder characterized as having difficulty comprehending language. This disorder varies in outcomes based on severity and localization of the brain damage, which is most commonly due to having a stroke. [ 3 ]
