Unformatted text preview: d form is decoded in the angular gyrus into the spoken form. Reading is all about
transforming certain sequence of letters into a particular sound. Learn to associate the speech sounds we know really well into visual word form. The agular gyrus
is critical for that. Once it is done, it sends its info to Wernicke's area, and now is is plugged into the language system. It is then sent via Arcuate fasciculus to
Brocas area, then to PMC, and M1.
Suggest to damage to any of these areas results in predictable loss of functions. Brain Damage & Language Deﬁcits! Apraxia: problems in speech production!
26:00 A patient with damage to Broca's area is not going to be able to implement this word plans to produce language; disconnect the arcuate fasciculus and you
would be able to hear the word, and produce language, but could not repeat what you just heard. Damage to those ﬁbers they couldn't repeat what they just heard.
Start w/ damage outside the language system. Speech apraxia: being unable to form motor plans, speciﬁcally to the production of speech. These actions are
speciﬁc to the motor coordination of speech (right excitation of the muscles of voice box), if they learned sign language, they would have not problems whatsoever.
But have trouble speaking words. "Know what words they want to say, but can't say it" Brain Damage & Language Deﬁcits! Apraxia: problems in speech production!
Broca’s aphasia: !
problems in language production!
Damage to Broca's area. Muscular and apparatus to produce
speech is just ﬁne, but seem "lost for words." They have a general
idea of what they want to say, but just can't produce it. Tona Tona
Tona Guy. In bilinguals, can be impaired in their ﬁrst language, but
not in their 2nd language. Brain Damage & Language Deﬁcits! Apraxia: problems in speech production!
Broca’s aphasia: problems in language production! Wernickes aphasia: Language production is ﬁne,
but have problems in language comprehension.
