Wernicke–Geschwind model

The Wernicke - Geschwind model ( after Carl Wernicke and Norman Geschwind ) provides a simplified representation of the neural representation of language ability dar. This language ability is dependent on the correct functioning of two areas of the left hemisphere. On the one hand from that of the Broca's area, which is responsible for producing language, is understood to others of the Wernicke's area, which is the area in which language.

Are these parts of the brain damaged by lesions, so it comes to aphasia. Is Broca's area is affected, it is called a Broca's aphasia. In this, the ability to understand language remains largely unaffected, however, the speech production is nearly impossible. Case of damage to Wernicke's area is located in front of a Wernicke's aphasia. In this case, speech understanding is affected in the first place. If the connection ( fasciculus arcuatus ) between these two parts of the brain is disturbed, this is referred to as conduction aphasia. In this both language comprehension and language production are intact. Badly hit only the ability to repetition because this forwarding the sequences understood by the Wernicke's area via the arcuate fasciculus the necessary in the body responsible for speech production Broca's area.
