Lesion and Language part 2 Flashcards
Wernicke’s area is responsible for what?
Language perception (speech sounds)
Arcuate Fasciculu is responsible for what?
Fiber tract from wernicke’s area to Broca’s area
Broca’s area is responsible for what?
Language production (speech actions)
Angular gyrus is responsible for what?
converting written words to spoken words
What is the pathway of spoken language perception? (4)
Auditory sensory pathway
Primary auditory cortex
wernicke’s area
higher level cortex
written language perception pathway (6)
visual sensory pathway
primary visual cortex
secondary visual cortex
angular gyrus
wernicke’s area
higher level cortex
Spontaneous spoken language production pathway (5)
higher level cortex
wernicke’s area
arcuate fasciculus
Brocas area
primary motor cortex
Repetition of speech pathway (6)
auditoru sensory pathway
primary auditory cortex
wernicke’s area
arucate fasciculus
brocas
primary motor cortex
Brocas aphasia: spontaneous speech repetition comprehension writing
- Slow, laboured, nonfluent, greatest difficulty with verbs, articles, pronouns, makes sense but ungrammatical, better fluency for memorized phrases, singing
- slow laboured, non fluent
- relatively spared (poor syntax/grammar comperhension_
- shows same errors as speech with impaired production
Wenicke's aphasia spontaneous speech repetition comprehension writing
- fluent, unlaboured, prosodic, but relatively meaningless (meaningless nonsense roundabout expression of meaning)
- fluent, unlaboured, but with neologisms
- severely impaired
shows same errors as speech with impairment in perception or comprehension
Global aphasia: spontaneous speech repetition comprehension writing
- severely impaired
- severely impaired
- severely impaired
- severely impaired
associated with damage to broca’s and wernicke’s area
Transcortical motor aphasia exhibits what symptoms
Broca’s aphasia with intact sentence repetition
Transcortical sensory aphasia exhibits what symptoms?
Wernicke’s aphasia with intact sentence repetition
mixed transcortical aphasia exhibits what symptoms?
Global aphasia with intact sentence repetition
Conduction aphasia: spontaneous speech repetition comprehension writing
- relatively intact, phonemic paraphasia and conduit d’approche
- severely impaired
- relatively intact
- relatively intact
associated with damage to arcuate fasciculus
