Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production. Language processing has been linked to Broca's area since Pierre Paul Broca ...
The area is involved in eye movements and possibly in the management of uncertainty. A functional magnetic resonance imaging study demonstrated that Brodmann area 8 activation occurs when test subjects experience uncertainty, and that with increasing uncertainty there is increasing activation.
The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [1] of the primate brain. In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus , consisting of a frontal and parietal portion. [ 2 ]
Most language processing takes place in Broca's area usually in the left hemisphere. [9] Damage to this region often results in a type of non-fluent aphasia known as Broca's aphasia. Broca's area is made up of the pars opercularis and the pars triangularis, both of which contribute to verbal fluency, but each has its own specific contribution.
The subcallosal area (parolfactory area of Broca) is a small triangular field on the medial surface of the hemisphere in front of the subcallosal gyrus, from which it is separated by the posterior parolfactory sulcus; it is continuous below with the olfactory trigone, and above and in front with the cingulate gyrus; it is limited anteriorly by the anterior parolfactory sulcus.
In 1861, Paul Broca studied patients with the ability to understand spoken languages but the inability to produce them. The damaged area was named Broca's area, and located in the left hemisphere’s inferior frontal gyrus (Brodmann areas 44, 45). Soon after, in 1874, Carl Wernicke studied patients with the reverse deficits: patients could ...
Brodmann area 45 (BA45), is part of the frontal cortex in the human brain.It is situated on the lateral surface, inferior to BA9 and adjacent to BA46.. This area in humans occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of the lateral sulcus (H), a portion of the orbital part of the inferior frontal gyrus (H).
Brodmann area 46, or BA46, is part of the frontal cortex in the human brain.It is between BA10 and BA45.. BA46 is known as middle frontal area 46.In the human brain it occupies approximately the middle third of the middle frontal gyrus and the most rostral portion of the inferior frontal gyrus.
