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 ...
Higher order functions of the association cortical areas are also consistently localized to the same Brodmann areas by neurophysiological, functional imaging, and other methods (e.g., the consistent localization of Broca's speech and language area to the left Brodmann areas 44 and 45).
Brodmann area 44, or BA44, is part of the frontal cortex in the human brain.Situated just anterior to premotor cortex and on the lateral surface, inferior to BA9.. This area is also known as pars opercularis (of the inferior frontal gyrus), and it refers to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex.
Broca's area is located in the left hemisphere prefrontal cortex above the cingulate gyrus in the third frontal convolution. [16] Broca's area was discovered by Paul Broca in 1865. This area handles speech production. Damage to this area would result in Broca aphasia which causes the patient to become unable to formulate coherent appropriate ...
[1] [2] [3] There are also specific functional differences in activity in the right and left VLPFC. [4] Neuroimaging studies employing various cognitive tasks have shown that the right VLPFC region is a critical substrate of control. [4] At present, two prominent theories feature the right VLPFC as a key functional region.
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).
In nine out of ten people with tone deafness, the superior arcuate fasciculus in the right hemisphere could not be detected, suggesting a disconnection between the posterior superior temporal gyrus and the posterior inferior frontal gyrus. Researchers suggested the posterior superior temporal gyrus was the origin of the disorder.
The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
