Still, Broca's area frequently emerges in functional imaging studies of sentence processing. [36] However, it also becomes activated in word-level tasks. [37] This suggests that Broca's area is not dedicated to sentence processing alone, but supports a function common to both. In fact, Broca's area can show activation in such non-linguistic ...
The differentiation of speech production into only two large sections of the brain (i.e. Broca's and Wernicke's areas), which was accepted long before medical imaging techniques, is now considered outdated. Broca's area was first suggested to play a role in speech function by the French neurologist and anthropologist Paul Broca in 1861.
He is best known for his research on Broca's area, a region of the frontal lobe that is named after him. Broca's area is involved with language. His work revealed that the brains of patients with aphasia contained lesions in a particular part of the cortex, in the left frontal region. This was the first anatomical proof of localization of brain ...
The arcuate fasciculus is a white matter pathway in the brain which contains two branches: a ventral branch connecting Wernicke's area with Broca's area and a dorsal branch connecting the posterior temporal region with the middle frontal gyrus. This dorsal branch appears to be particularly important for phonological working memory processes. [183]
The left opercular part of the inferior frontal gyrus is a part of the articulatory network involved in motor syllable programs. The articulatory network also contains the premotor cortex, and the anterior insula. These areas are interrelated but have specific functions in speech comprehension and production.
The brain structures of chimpanzees are very similar to those of humans. Both contain Broca's and Wernicke's homologues that are involved in communication. Broca's area is largely used for planning and producing vocalizations in both chimpanzees and humans.
In neuroanatomy, the arcuate fasciculus (AF; from Latin 'curved bundle') is a bundle of axons that generally connects Broca's area and Wernicke's area in the brain. It is an association fiber tract connecting caudal temporal lobe and inferior frontal lobe .
Signers with damage in Broca's area have problems producing signs. Those with damage in the Wernicke's area (left hemisphere) in the temporal lobe of the brain have problems comprehending signed languages. Early on, it was noted that Broca’s area was near the part of the motor cortex controlling the face and mouth.
