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.
The differentiation of speech production into only two large sections of the brain (i.e. Broca's and Wernicke's areas), which was accepted long before medical imaging techniques, is now considered outdated. Broca's area was first suggested to play a role in speech function by the French neurologist and anthropologist Paul Broca in 1861.
In neuroanatomy, the arcuate fasciculus (AF; from Latin 'curved bundle') is a bundle of axons that generally connects Broca's area and Wernicke's area in the brain. It is an association fiber tract connecting caudal temporal lobe and inferior frontal lobe. [1]
The arcuate fasciculus is a white matter pathway in the brain which contains two branches: a ventral branch connecting Wernicke's area with Broca's area and a dorsal branch connecting the posterior temporal region with the middle frontal gyrus. This dorsal branch appears to be particularly important for phonological working memory processes. [183]
Many researchers now include BA45 in the prefrontal cortex because together with BA44 it makes up an area of the frontal lobe called Broca's area. [20] Broca's Area is widely considered the output area of the language production pathway in the brain (as opposed to Wernicke's area in the medial temporal lobe, which is seen as the language input ...
Two structures are often described in this brain regions, namely the nuclei of the vertical and horizontal limbs of the diagonal band of Broca (nvlDBB and nhlDBB, respectively). nvlDBB projects to the hippocampal formation through the fornix and it is the second largest assembly of cholinergic neurons in the basal forebrain whereas nhlDBB projects to the olfactory bulb and it does not have a ...
