Question

60c. Patients with Broca's aphasia (defined clinically by their language deficits, including apraxia of speech) will always have lesions in Brodmann's areas 44 and 45 (Broca's area).

a. true

b. false

60 d. The left hemisphere language network involves white matter tracks connecting the temporal and frontal lobes. One dorsal track connects the posterior temporal cortex and the lateral inferior frontal cortex, and is call the ______, while the other ventral track connects more anterior and medial temporal cortex with the inferior and orbital frontal cortex, and is called the _________.

a. optic chiasm/centre median

b. trigeminal nerve/optic nerve

c.corpus callosum/fornix

d. arcuate fasciculus/uncinate fasciculus

Answer 1

60c. The answer is , "true".

Patients with Broca's aphasia will always have lesions in Brodmann's areas 44 and 45. This is because a lesion in these areas imply difficulty in speech, word pronunciation, motor aphasia, dysphagia, agraphia.

60d. The answer is d, "arcuate fasciculus/uncinate fasciculus".

Arcuate fasciculus is a bundle of axons that forms part of the superior longitudinal fasciculus, forming an association of fibre tract. The uncinate fasciculus is a white matter association tract of the brain that links parts of the limbic system in the temporal lobe with frontal ones such as orbitofrontal cortex. This part is affected in several psychiatric conditions.
