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).

Broca's area," Cognitive Brain Research, vol.
"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.
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).
Broca's area of the brain is active not only when you speak, but also when you wave your hands.
