Geschwind’s area is associated with which aphasia?
Transcortical sensory aphasia
Language is lateral: please mention what the left and right hemispheres are involved in.
- Left hemisphere: primary site of speech comprehension and production
- Right hemisphere: involved in the control of prosody (patterns of stress and intonation in a language)
What is this: Difficulty in producing or comprehending speech, not because of deafness or simple motor deficit caused by brain damage
Aphasia
Are motor deficits aphasia?
No, the patient has difficulty comprehending, repeating, or producing meaningful speech
Identify the aphasia:
Right: Picture of a boy being hit in the head by a baseball
Wrong: The boy is catch… the boy is hitch… the boy is hit the ball.

What’re the 3 characteristics of broca’s aphasia?

Damage to left superior temporal lobe
What defines pure word deafness?
Impairment in recognizing words (comprehension would affect written words)
- Does not understand speech, recognize non-speech sounds (barking, honking)
Where is the lesion for transcortical sensory aphasia?
The damage extends past Wernicke’s area into a region that surrounds posterior part of the lateral fissure where temporal, occipital and parietal lobes converge
- Damage to Geschwind’s area
Define the aphasia: difficulty comprehending speech and producing meaningful spontaneous speech but can repeat the speech
Transcortical sensory aphasia
What lesion exists for the transcortical motor aphasia?
Lesion to frontal lobe proximal to Broca’s area
Define the aphasia: difficulty making speech and but can comprehend and repeat speech. Impaired fluency but intact comprehension and repetition.
Transcortical motor aphasia
What are the 3 characteristics of Wernicke’s aphasia?
1) Recognition of spoken word (PWD)
2) Comprehension of the meaning of words (TSA)
3) Ability to convert thoughts into words
What defines conduction aphasia?
Meaningful fluent speech, good comprehension but poor repetition
What lesions exist for individuals with conduction aphasia?
