Document Summary

Reading 8: broca"s area and broca"s aphasia mohr why it is wrong: Broca"s aphasia was the first aphasic syndrome attributed to focal injury (lesion) of the brain. The literature suggests that the destruction of broca"s area and its immediate surrounding does not reliably produce the deficits currently envisioned as characteristic of the syndrome of broca"s aphasia. Instead, little persisting disturbance in articulation seems to occur, and frequently no significant persisting disturbance in language function is present. The syndrome currently referred to as broca"s aphasia arises instead from a considerably larger brain injury that encompasses most of the operculum, insula, and subjacent white matter. Fleichsig"s rule: was devised from studies of the anatomy of the cerebral white matter, and arose in part from speculations concerning the function of broca"s area. According to this theory, the primary cortex related the brain to the periphery by the major motor and sensory pathways.
