There must be an alternate neural route connecting Broca's area and Wernicke's area
An adult with damage to Wernicke's area
may articulate well and form grammatically correct sentences, but provides very little coherent information in his speech.
In the Wernicke's area
of the brain where language processing takes place, the norm in a nondyslexic is to see very structured, smaller-layered cells.
Scientists have long thought that human speech is processed towards the back of the brain's cerebral cortex, behind auditory cortex where all sounds are received - a place famously known as Wernicke's area
after the German neurologist who proposed this site in the late 1800s based on his study of brain injuries and strokes.
This region came to be known as Wernicke's area
, connected to Broca's area by a neural pathway called the arcuate fasciculus.
The brain pathway for normal reading has also been identified (from visual area to angular gyrus to Wernicke's area
to Broca's area), as have the sequences involved in memory storage.
These include Wernicke's area
, which contributes to language comprehension, as well as parts of the visual cortex and a section of the association cortex considered pivotal to integrating the sight of printed letters with their corresponding sounds.
Within this latter part of the brain, Wernicke's area
is believed to be responsible for finding words and feeding them to other parts of the brain.
(W) and surrounding areas, including angular gyrus (AG) and supramarginal gyrus (SG), are heteromodal areas that may be responsible for the integration of spoken and written word forms with arbitrary associations that give rise to meaning or semantics (Mesulam, 1998; Pugh et al.
In humans, a swath of neural tissue, known as Wernicke's area
, encompasses the entire planum temporale and helps to orchestrate language comprehension.
Broca's area, related to speech production, and Wernicke's area
, associated with comprehending speech, were supposed to be the two centers in the brain associated with verbal communication.
