WERNICKE'S AREAS


A large region of the parietal and temporal lobes of the left cerebral hemisphere, thought to be essential for understanding and formulating coherent, propositional speech. Also called sensory speech center, Wernicke's area.
Meaning #1: the auditory word center; located in the posterior part of the superior temporal convolution in most people Synonym: Wernicke's center
Wernicke's area is named after Karl Wernicke, a German neurologist and psychiatrist who, in 1874, discovered that damage to this area could cause a type of aphasia that is now called Wernicke's aphasia or receptive aphasia.
This condition results in an impairment of language comprehension and in speech that has a natural-sounding rhythm and a relatively normal syntax, but otherwise has no recognisable meaning (a condition sometimes called fluent or jargon aphasia).
Wernicke's work initiated the study of this brain area and its role in language. It is particularly known to be involved in the understanding and comprehension of spoken language
