Wernicke's area also has massive connections through the arcuate fasciculus with Broca's area
(B), which tends to show later peaks of activation in language tasks (Thierry, Boulanouar, Kherif, Ranjeva, & Demonet, 1999).
The inferior margin borders on the Sylvian fissure (lateral fissure) separating it from the temporal lobes.[18,23] The prefrontal region lies anterior to the motor area, located just anterior to the central fissure, while Broca's area
is situated at the inferior frontal gyrus.

and inflectional morphology: evidence from Broca's aphasia and computer modeling," Cortex, vol.
Instead, it was Broca's area
-- a primary language center of the brain -- that was sensitive to the syllable hierarchy.
These additional targets included regions involved in speech production, such as Broca's area
in the prefrontal cortex.
* 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.
Thus, for example, the left posterior inferior frontal region, Broca's area
, was linked to speech production (where brain damage would result in articulatory problems); the left posterior temporal region, Wernicke's area, to auditory speech recognition (where damage would yield impaired language comprehension); and the arcuate fasciculus connecting these anterior and posterior regions to repetition (where damage would impair production by repetition but preserve comprehension).
"This finding raises the possibility that the premotor circuits important to planning and controlling speech in our own brains also play an important role in auditory learning of speech sounds during early infancy." This brain region, known as Broca's area
, is located in the frontal lobe of the left hemisphere.
The researchers found that an area of the brain known as the left pars opercularis - part of the Broca's area
, a region of the brain involved in speech production but also in analysing and separating speech sounds - correlated with the amount of training in transcription that a phonetician had undergone.
These 'perception-and-action' cells reside within Broca's area
, a brain structure involved in speech production and situated roughly where the monkey premotor cortex lies.
, 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.
Hearing unexpected chords was linked to magnetic activity in a left-brain region known as Broca's area
and in adjacent right-brain tissue.
