STUDY GUIDE
Ventral Stream - ANS ✔✔maps sensory phonological representations into lexical conceptual
information (sound to meaning)
e.g /kat/ is understood as cat
Dorsal Stream - ANS ✔✔maps sensory phonological representations into articulatory
representations (sound to articulation)
e.g. processes cat as /k/ /a/ /t/
Conceptual network - ANS ✔✔semantic understanding
Brocas aphasia - ANS ✔✔-nonfluent
-areas 44 and 45 of the frontal lobe
-difficulty with passives and complex grammar
-agrammatism, telegraphic speech, anomia, phonemic paraphasia
-IS aware of deficits
Transcortical Motor - ANS ✔✔-non fluent
-frontal lobe watershed region (6,8,9,10,46)
-difficulty with passives and complex grammar
-telegraphic speech, literal and semantic paraphasia
-differs form Broca''s aphasia because repetition is intact
Global - ANS ✔✔-non fluent
-MCA vascular territory
, -severe impairments
-may be nonverbal, jargon and sterortypy
-gestures and facial expression
Wernicke's Aphasia - ANS ✔✔-fluent
-posterior portion of temporal lobe (22)
-anomia, semantic and phonemic paraphasia, jargon, neologism, circumlocutions, press of
speech, logorrhea
-poor self monitoring skills
-lack of awareness of deficits
-relatively intact syntactic production
Transcortical Sensory Aphasia - ANS ✔✔-temporal watershed region, angular gyrus (39),
posterior middle temporal gyrus (37)
-paraphasia, neologisms, logorrhea
-intact repetition (echo others words sometimes)
-impaired repetition
-awareness is good
Conduction Aphasia - ANS ✔✔-arcuate fasciciulus, supramarginal gyrus (40)
-repetition impairment
-phonemic paraphasia and conduit dapproache
Anomic Aphasia - ANS ✔✔-lesion site is varibale, often angular gyrus (39)
-word finding issues, paraphasia, circumlocution, filers
-comprehension and syntactic production is spared
