  Carl Wernicke (www.whonamedit.com)
Karl Wernicke was born in the small town of Tarnowitz in Upper Silesia, which was then a part of Prussia, where his father was a civil servant.
Wernicke was only 26 years of age when he, in 1874, published "Der aphasische Symptomenkompleks" in which he first described sensory aphasia, localised at the temporal lobes, as well as alexia and agraphia.
Wernicke did not believe in specific psychiatric disease entities, and he was an ardent adversary of Emil Kraepelin (1856-1926), considering the latter's classification as not being sufficiently scientific.

 Wernicke - Medicow   (Site not responding. Last check: 2007-10-08)
Wernicke's area, which occupies a crescentic zone in the posterior third of the superior temporal convolution of the dominant hemisphere, just lateral to the transverse temporal gyrus of Heschl, has been called the center for the recognition, interpretation, and recall of word symbols and their association as a function of language.
Wernicke's aphasia, by contrast, results from damage to the posterior region of the left hemisphere, specifically in the areas adjacent to the primary auditory cortex on the posterior portion of the superior left temporal gyrus.
Wernicke's area is located within the left superior temporal lobe and extends from the border zones of the primary auditory reception area toward the inferior parietal lobule.

 Aphasiology
Such a view is supported by the complementary nature of Wernicke's aphasia, described by the German neurologist Karl Wernicke, a contemporary of Broca.
Wernicke's aphasics produce speech that seems fluent and grammatical, but is largely devoid of sensible content.
Wernicke's aphasia is associated with the posterior superior temporal gyrus, known as "Wernicke's area", an area adjacent to cortex responsible for auditory processing.

 MedFriendly.com: Wernicke’s syndrome
Wernicke's syndrome is a deficiency in the vitamin, thiamin that is due to poor nutrition.
Wernicke's syndrome is also associated with double vision, difficulty in spontaneous eye movements, altered size of the pupils (the small fl circle in the middle of each eye), and nystagmus (rhythmic involuntary jerking or swinging movements of the eyes).
Brain damage in Wernicke's syndrome typically occurs in the hypothalamus (an area in the lower part of the brain that is important for many bodily functions such as sleep, thirst, and hunger) and the mammillary bodies (a part of the hypothalamus that is important for memory).

 Free Essay Broca vs. Wernicke's aphasia - a double dissociation
Wernicke’s patients demonstrated other types of language problems, their speech is rapid, fairly well formed, but empty of meaning, neologisms are very common and comprehension is severely impaired.
Wernicke’s area is therefore located in the temporal lobe (rather than the frontal lobe), between the primary auditory cortex and the angular gyrus.
Wernicke’s area is responsible for connecting symbols to their referents and for the access and manipulation of words, as it is located behind the auditory projection zone.

 Carl Wernicke (1848-1904)
Wernicke estableció la afasia sensorial como entidad clínica situando la lesión en la parte posterior del lóbulo temporal (primera circunvolución temporal izquierda), y cuya principal evidencia era la pérdida de la comprensión verbal o auditiva.
Wernicke también formuló una teoría general sobre la afasia que proponía la relación entre cada uno de los componentes del lenguaje y un área cerebral determinada.

Wernicke was a 1965 graduate of the St. Francis School of Nursing and a regular member of Christ the King Church in Columbus for almost 40 years.
Wernicke often served the most underprivileged areas and would not hesitate to visit the roughest neighborhoods at all hours of the day and night to care for her patients.
She is survived by her son, Bryon Wernicke of Columbus; daughters, Amy Fox of Columbus and Dr. Annamarie Wernicke (Dr. Tim) Milburn of Medina; sister, Margaret Zerwick; brother, Ralph Schwob; and seven grandchildren.

 Wernicke-Korsakoff syndrome - Definition, Description, Causes and symptoms, Demographics, Diagnosis, Treatments, ...
The first phase of the condition, called Wernicke's encephalopathy, was described by German neurologist and psychiatrist Karl Wernicke in 1881.
The classic presentation with acute onset of Wernicke's encephalopathy is fairly rare, about 0.05% of all hospital admissions, although this does not account for patients who do not seek medical attention.
Wernicke's encephalopathy is diagnosed when patients seek medical attention and have the classic trio of signs: mental confusion, eye movement disorders, and ataxia.

 [No title]
He was aware of a toxic factor being important in its etiology, but he did not realize that this was nutritional. Wernicke aimed at a natural system for the classification of mental disorders, chiefly based on the anatomy and pathology of the nervous system.
He had not much contact with his younger pupils, but his way of examining patients and his demonstrations were so lucid and stimulating that those who had the good fortune to attend his clinics were deeply influenced in their further consideration of neurological and psychiatric problems.
His influence can be seen in the work of a whole generation of German psychiatrists.

After death, this patient was found to have a lesion in the lower posterior portion of his left frontal lobe, a region that continues to be labeled as Broca's area.
In 1874, Karl Wernicke followed this observation with a description of a patient who was able to speak, but could not understand language.
This patient's brain abnormality was found in what is now called Wernicke's area, a portion of the left posterior temporal lobe.

WERNICKE’S AREA - Wernicke’s area lies in the temporal lobe and is most typically found in the left hemisphere, as this is where the majority of people have brain areas specialized for language skills.
The German neurologist Karl Wernicke discovered in 1874 that damage to this area could cause a type of aphasia, resulting in a pronounced impairment of language comprehension and speech.
One theory of language production holds that Wernicke’s area is responsible for individual words, while Broca’s area is responsible for grammar.

The two areas of the brain that are used for learning and speaking language are Broca’s Area and Wernicke’s Area.
In 1876, Karl Wernicke found that damage to a different part of the brain, caused similar problems.
Broca’s area and Wernicke’s area are joined by a group of nerves called arcuate fasciculus (Which resembles a bunch of guitar strings).

Karl Wernicke, a Polish neurologist, published his description of Wernicke’s encephalopathy in 1881 and Sergei Korsakoff, a Russian psychiatrist, published the first of a number of papers describing the condition which bears his name in 1887.
If the patient has experienced an episode of Wernicke’s encephalopathy then the date of that episode may be the ‘cut-off point’ after which they are unable to retain memories for very long.
Wernicke’s encephalopathy is an acute neuropsychiatric condition due to an initially reversible biochemical brain lesion caused by overwhelming metabolic demands on cells which have depleted intracellular thiamine (vitamin B1).

Back in the 1860s and 1870s, two neurologists (Paul Broca and Karl Wernicke) observed that when people had damage to a particular area on the left side of the brain that they had speech and language problems.
They noticed that people with damage to these specific areas on the right side usually did not have any language problems.
