Chap. 3 Audition And Language Flashcards
What is the precentral gyrus responsible for?
Motor
What is the postcentral gyrus responsible for?
Sensory
Genetic foundation for language?
FOX P2 gene demonstrates deficits in sequencing articulatory patterns (ex: problems with pronunciation, syntax, and grammar)
Differences in gross anatomical structures between those who were affected and those who weren’t by the gene.
What is aphasia? What are the types?
Deficits in language comprehension/production
- broca’s
- wernicke’s
- conduction (rare)
What is dysarthria?
Loss of control of articulatory muscles (could affect how speech is produced, lots of errors)
What is apraxia?
Deficits in motor planning of articulations
Issue with the brain’s planning system for speech movement
What is anomia?
Specific form of aphasia, deficit in object naming
Broca’s aphasia
Difficulties in speech production
Mostly content words & effortful
Wernicke’s aphasia?
Difficulties in language comprehension
May not understand, so they put out meaningless sentences even though it is intact
What is the wernicke’s-Lichtheim model?
Deficits characterized along the pathway from sound input to speech input.
Proposed conduction aphasia
What is conduction aphasia?
Poor speech repetition.
The result of the damage between Broca’s area and wernicke’s area.
IMPORTANT for the consideration of connectivity
What is the most common stroke site?
MCA = middle cerebral artery
What is the POST ITL responsible for?
Access/ integrating semantics
What is the frontal regions responsible for?
Speech comprehension
For understanding speech, what is the perisylvian language system (spoken language comprehension) composed of?
2 ventral pathways and 2 dorsal pathways
