New location for Wernicke's area

[Guest guest]

Someone on a different group shared this with me yesterday.

" Rauschecker and DeWitt searched the peer-reviewed, scientific literature for

studies that investigated auditory speech perception in humans using different

scanning methods — either from functional magnetic resonance imaging (fMRI) or

positron emission tomography (PET). They found 115 brain imaging studies of

speech perception, which in total had included over 1,900 participants and

generated over 800 brain coordinates for speech processing. They then used a

type of analysis that allowed them to measure the degree of agreement among

brain coordinates from these studies.

The results pinpoint the location of Wernicke's area to be in the left temporal

lobe, and specifically to be in the superior temporal gyrus, in front of the the

primary auditory cortex. "

Well, when they start with the statement that Scientists have long believed that human speech is processed towards the back of the brain's cerebral cortex, behind auditory cortex 

That kind of stops me right at the front door.  Everything I've ever seen or heard was that Broca's area is what produces speech. Wernicke's area is involved in the understanding of spoken or written language.
