aphasias: Aphasia after lesions including the frontal operculum.
Specifically, Flinker and fellow researchers have found that Broca's area
-- which is located in the frontal cortex above and behind the left eye -- engages with the brain's temporal cortex, which organizes sensory input, and later the motor cortex, as we process language and plan which sounds and movements of the mouth to use, and in what order.
Their brains, while relatively larger than chimpanzees, are small and lack a human-like Broca's area
, indicating very limited syntactical ability; their technology also supports the notion that hierarchical thinking processes were minimal.
According to the data, processing of complex syntactic sentences, but not subvocal activity, led to an increase in blood flow in Broca's area
This region came to be known as Wernicke's area, connected to Broca's area
by a neural pathway called the arcuate fasciculus.
MR results showed that Broca's area
is apparently normal in autistic boys who have normal language capabilities.
, a region on the left side of your brain just behind your forehead is the "vocalizer.
The part of the brain involved, called Broca's area
,deals with memory, language processing and organisation.
The team, led by Kuniyoshi Sakai, assistant professor at the University of Tokyo, says a specific part of Broca's area
in the frontal cortex is responsible for grammar, while a different part manages vocabulary.
To determine if Broca's area
plays a critical role in human imitation, we conducted a repetitive transcranial magnetic stimulation (rTMS) study, transiently disrupting cortical activity in three sites: the left inferior frontal gyrus (Broca's area
), right inferior frontal gyrus, and an occipital control condition.
There seem to be a certain number of direct or indirect connections between the ambiguous nucleus and certain central areas--especially Broca's area
, the motor cortex, and the anterior cingulum--but their significance is poorly understood.
There's a part of the brain called Broca's area
that Milbank says "directs the production of clear and intelligible speech.
