Nr 569 final exam
language is a _____ hemisphere dominant function in ___% of
right handed people, and _______% of left handed people
- left
- 97%
- 60-70%
broca's area is responsible for _________. It s located in the
________ lobe, and is associated with Brodmann area(s)
_______
- speech production
- L frontal
- 44 and 45
wernicke's area is responsible for _________. It s located in the
________ lobe, and is associated with Brodmann area(s)
_______
- speech comprehension
- L temporal lobe
- 22
speech comprehension (sensory) connects to speech production
(motor) via the _________, which is a bundle of _________
- arcuate fasciculus
- white matter tract
what type of aphasia occurs when the arcuate fasciculus has a
lesion?
,conduction aphasia
aphasia
syndromes that diminish or abolish the ability to comprehend
and/or produce language as a vehicle for communicating
meaningful statements
broca's aphasia speech characteristics (3):
- comprehension is intact/impaired
1) labored, slowed speech, impaired articulation, lacking normal
intonation
2) cannot complete complex sentences
3) speech lacks grammatical structure but grammatical
judgments intact
- comprehension is intact
wernicke's aphasia speech characteristics (2):
- comprehension is intact/impaired
1) effortless, melodic speech produced at normal rate
2) content unintelligible with frequent errors
- comprehension is impaired
conduction aphasia characteristics (5)
- some components of both Broca's and Wernicke's aphasia
- comprehension of simple sentences
- production intelligible speech
- cannot repeat sentences verbatim
- cannot assemble sounds effectively
, T/F: broca's and wernicke's aphasia affect writing
true
T/F: language processing involves motor cortex
true
- e.g.: the language circuitry for the word "kick" wold
preferentially activate sensorimotor circuitry involved in
performing leg-related actions
cortical activation during movement vs. passive reading of
action words
during movement, get activity in tongue, finger, and foot areas
when asked to move
during reading, get similar activity in tongue, finger, foot areas
of motor cortex ("lick" "pick" "kick")
what happens if you apply HF-rTMS to area of the motor cortex
that correspond to a body part (e.g.: arm; leg)
decreased response time for word recognition
e.g. TMS stimulates L motor cortex leg area --> faster
recognition of "kick"
left hemisphere functions
- lexical and syntactic language
- writing
- speech
language is a _____ hemisphere dominant function in ___% of
right handed people, and _______% of left handed people

- 60-70%
