Input, output
What is the function of the motor association areas?
Organizing and planning actions (planner)
What is the function of the sensory association areas?
Interpreting and making sense of incoming sensory information (interpreter)
What are the frontal association cortices?
Premotor regions
Frontal eye fields
Prefrontal cortex
Broca’s area***
What is the frontal association area that is important for language?
Broca’s area
Where is Broca’s area located?
Ventral lateral
Inferior frontal gyrus
Pars triangualris, pars opercularis
What is the function of Broca’s area?
Motor programming for speech
Processing phonological and syntactic information
Verbal working memory
Lexical semantic processing
What happens with deficits to Broca’s area?
Deficit in production of language
Content words better
Nouns better than verbs
Agrammatism (telegraphic speech because function words are left out)
Apraxia of speech
What is the temporal association cortex area that is important for language?
Wernicke’s area in superior temporal gyrus
What is the function of Wernicke’s area?
Auditory association
Make sense of auditory information
Language comprehension
Lexical/semantic processing
Temporal association cortex: the medial temporal gyrus is involved with
Lexical/semantic
Comprehension
