  2. Broca's area - Wikipedia

    en.wikipedia.org/wiki/Broca's_area

    Still, Broca's area frequently emerges in functional imaging studies of sentence processing. [36] However, it also becomes activated in word-level tasks. [37] This suggests that Broca's area is not dedicated to sentence processing alone, but supports a function common to both. In fact, Broca's area can show activation in such non-linguistic ...

    Furthermore, Broca's area is structurally related to the thalamus, and both are engaged in language processing. [5] The connectivity between both areas is two thalamic nuclei, the pulvinar, and the ventral nucleus, which are involved in language processing and linguistic functions similar to BA 44 and 45 in Broca's area. [5]

  4. Arcuate fasciculus - Wikipedia

    en.wikipedia.org/wiki/Arcuate_fasciculus

    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 .

  5. Inferior frontal gyrus - Wikipedia

    en.wikipedia.org/wiki/Inferior_frontal_gyrus

    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.

  6. Brain asymmetry - Wikipedia

    en.wikipedia.org/wiki/Brain_asymmetry

    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 ...

  7. Wernicke's area - Wikipedia

    en.wikipedia.org/wiki/Wernicke's_area

    Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...

  8. Insular cortex - Wikipedia

    en.wikipedia.org/wiki/Insular_cortex

    The sensory speech region, Wernicke’s area, and the motor speech region, Broca’s area, are interconnected by a large axonal fiber system known as the arcuate fasciculus which passes directly beneath the insular cortex. On account of this anatomical architecture, ischemic strokes in the insular region can disrupt the arcuate fasciculus. [15]

  9. Expressive aphasia - Wikipedia

    en.wikipedia.org/wiki/Expressive_aphasia

    Therefore, when Broca's area or surrounding areas in the left hemisphere are damaged, hemiplegia or hemiparesis often occurs on the right side of the body in individuals with Broca's aphasia. Severity of expressive aphasia varies among patients. Some people may only have mild deficits and detecting problems with their language may be difficult.
