11-Language Flashcards
receptive language
brain derives meaning from auditory speech or visual language input
-comprehension
expressive language
brain produces spoken or written language output to communicate meaning
-production
anomia
difficulty finding words
-difficulty generating the words used to label things in the world.
dysarthria
difficulty controlling the muscles used in speech
-difficulty saying words
apraxia
impairment of motor planning of speech articulation
-difficulty pronouncing words
aphasia
deficit in language comprehension or production
historically Broca’s area has been associated with speech production…what new information do we have on this topic
- Broca’s area does not participate in production of individual words, but coordinates the transformation of information processing across large-scale cortical networks involved in spoken word production, prior to articulation.”
- Connects representations of words in temporal cortex to motor areas for articulation
Wernicke’s area is associated with speech comprehension deficits …how has this view recently changed
there isn’t a completely clear association with lesions in Wernicke’s Area and Wernicke’s Aphasia – also involves surrounding tissue
mental lexicon.
the collective store of information about the semantics, syntax, orthography, and phonology of words
what is the neural correlated of the mental lexicon
- inferior and medial temporal cortex
- left temporal lobe
process of spoken word comprehension and neural correlates
- PMTG :posterior middle temporal gyrus
- MTG: middle temporal gyrus
- ITG: inferir temporal gyrus
- PCC: posterior cingulate cortex
process of written language comprehension and neural correlates
-left occipitotemporal cortex
language production …neural correlates
- inferior temporal
- left frontal operculum (Brocas)
- motor cortex
- supplementary motor area
- insula
- basal ganglia
- cerebellum
- thalamus
language is in left or right hemisphere
left
which brain area connects words to motor
Broca’s area
