lecture 10 Flashcards
brocas aphasia
language production impaired
wernickes aphasia
difficulty comprehending speech
but perfect fluent speech
speech is meaningless
Wernickes geschwind model
describes how different regions with different functional roles interact in the production and comprehension of language
brocas area is involved in
planning
wernickes area is involved in
comprehension
auditory cortex is involved in
sensory processing od speech sounds
motor cortex is involved in
production of articulatory movements
arcuarte fascículos
bundles of axons that link Wernicke and brocas area
repeating spoken words
auditory cortex processes speech sounds, meaning accessed in Wernicke area , signals transmitted via arcuarte fasciculus to brocas area
Broca forms speech
repeating written words
written words processed by visual cortex , info transmitted to angular gyrus, visual code is converted into phonological code , interrupted in wernickes area
brocas area formulates
speech plan the is implanted by motor cortex
wernickes area responsible for
comprehension and process of meaning
without connection of acrualte fabuculus
impossible to read out loud and repeat info
regions intact - arcuate fasculusus
comprehension and production - unaffected
reading and repetition disrupted = conduction aphasia
when repeating words we expect
brocas area to be active but its not
