Thursday - 1 - Fitz - language Flashcards
prosody
emotional emphysis of words
primary language pathway
name the areas in the brain it goes to
audio and visual corticies
to wernicke’s area (posterior temoral lobe)
to arcuate fascilicus
to broca’s area
to motor cortex
Gershwind’s territory
where in brain
synapses with what
lesions cause what
inferior parietal lobe
synapses with wernicke’s and broca’s area
“tip of the tounge”
lesions in this area make it so you can think of somthing but just cant say it
stereonosis
what is it
contralateral or ipsilateral
feeling a ball in you hand for example
contralateral to the brain
writing and speech
which side of the brain
left side of the brain
prodosy
what is it
which side of brain
emotional context of speech
right side of the brain
Most of language function is in which cortex
which handed-ness is this more true for?
left
at least for
95% of RH
60% of LH
fluent speech aphasia
results from lesion in what
can generate speech
cannot comprehend i.e. they don’t know that their speech is babble
wernike’s
nonfluent (expressive) speech aphasia
results from lesion in what
cannot generate speech
can comprehend
broccas area
most common aphasia
lesion where
Sx
receptive aphasia aka fluent aphasia (wernicke’s)
deficits in auditory and written comprehension
patient doesn’t notice there is a problem, but they don’t make sense
conduction aphasia
lesion where
Sx
lesion in arcuate fasiculate nucleus:
inability to repeat words back
lesion in gershwind:
inability to come up with words
global aphasia
lesion where
Sx
large areas of damage, no distinctive area
profound deficits in comprehension and expression
aprosody
lack comprehension and expression of emotional qualities (right brain equivalent of lesions in wernike’s)
apraxia of speech
different outputs each time a word is attempted
most likely in children
dysarthrias
problems in the efferent output from the motor cortex in speech
cant articulate
aphasia
etymology of the word
a - without
phasia - speech
TRUE APHASIA IS SUPER RARE, THE TERM IS USED A LOT BUT DYSPHASIA IS A MORE ACCURATE TERM
what area executes the final pathway for speech?
nucleus ambiguus
go from thought to spoken word in a brain pathway
prefrontal cortex
gerschwind’s
wernicke’s
arcuate fasciculus
broca’s (prosody from right side comes in as well)
motor cortex
nucleus ambiguus
vagus, hyoglossal, glossopharyngeal, nerves
Where does Fitz have a lesion in her brain from a concussion?
gerschwinds
pathway in your brain as you are taking notes
cochlea
primary auditory cortex
wernicke’s area
arcuate fasiculus
brocas
motor cortex
corticospinal tract
alpha motor neurons in ventral horn of cervical spine
Name the main structures in the brain that we know are lateralized
what is flipped if you are left handed
visual fields
right touch/left touch (stereognosia)
following may be flipped in left handedness:
positive emotion on left, negative on right
writing (this is 100% for sure flipped in) and speech on left, rudimentary speech and prosody on right
