Overactivation in the inferior frontal gyms including Broca's area
. Some investigators have found more activation using MEG (magnetoencephalography) or fMRI among dyslexics in heteromodal regions of the inferior frontal gyrus, including Broca's area
, on a reading task visually presented (Salmelin et al., 1996; Shaywitz et al., 1998).

"We showed that distinct linguistic processes are computed within small regions of Broca's area
, separated in time and partially overlapping in space," said Sahin.
According to a report in New Scientist, to get a better handle on how Broca's area
may have changed in the 6 million years since humans and chimpanzees last shared a common ancestor, Sherwood's team examined thin sections of Broca's area
, collected from 12 chimpanzees after they died of natural causes.
"Engaging the part of the brain called the Broca's area
helps disengage the area responsible for all that internal worry dialogue.
"So while the results broadly agree with each other, there's no standard set of regions that we know are involved in humor, the way we know about Broca's area
Neuroimaging studies revealed that PhonoS recruits the left dorsal pathway via the angular gyrus (AG) or supramarginal gyrus (SMG) and involves the ventrolateral prefrontal cortex (VLPFC) and the lower part of Broca's area
. On the other hand, LogoS recruits the left ventral pathway via the inferior medial temporal lobe involving the fusiform gyrus (FG) and the pars triangularis/pars opercularis [5-8].
Surprisingly, P3 with a tumor near Broca's area
did not suffer from preoperative language deficits probably due to functional reorganization.
Traditionally, it has been accepted that speech production is controlled by the so-called Broca's area
corresponding to Brodmann's area (BA) 44 (pars opercularis of the left inferior frontal gyrus) (e.g., Goldstein, 1948; Damasio & Geschwind, 1984; Head, 1926; Hecaen, 1972; Luria, 1947/1970).
of the brain is active not only when you speak, but also when you wave your hands.
Since the tumour was in the Broca's area
, the neurosurgeon indicated surgical treatment in awake condition under intraoperative neurophysiological monitoring of the patient.
