Speech and Language Flashcards
different levels of motor speech system
conceptual
linguistic planning
motor planning/programming
motor execution
conceptual brain areas
prefrontal cortex
temporal-parietal regions
what happens in conceptual
generate desire and thought to communication
disorder of conceptual
cognitive communication disorder (dementia, tbi)
linguistic planning areas
wernickes area
brocas area
arcuate fasciculus
what happens in linguistic planning
choose words, organize grammar and syntax
disorders of linguistic planning
aphasia
motor planning and programming areas
premotor cortex
supplementary motor area
basal ganglia
cerebellum
what happens in motor planning
plan HOW to move articulators to produce sounds
disorders in motor planning
apraxia of speech
execution areas
primary motor cortex
brainstem
motor nuclei
what happens in execution
send motor signals to muscles for speech
disorders of execution
dysarthria
symptoms of aphasia
difficulties in speech, understanding, reading, writing
fluent aphasia
wernickes
intact fluency, impaired comprehension
non fluent aphasia
brocas
impaired fluency
intact comprehension
alexia
difficulty reading
agraphia
difficulty writing
brain and language connection: language processing relies on a network
brocas area
wernickes area
arcuate fasciculus
basal ganglia and cerebellum
brocas
speech production and syntax
wernickes
language comprehension
arcuate fasciculus
connects brocas and wernickes
basal ganglia and cerebellum
fine tune motor aspects of speech
brain and language connection: knowledge of these pathways helps SLPS
diagnose accurately
plan treatment
educate patients
