I have a question that got me for a long time.
Gerstman's syndrome: leision in the parietal lobe-angular gyrus lesion. this
syndrome is characterized with alexia and agraphia. I understand alexia is
b/c it blocks the written language function from visual cortex. But why it
also has agraphia? Consider the Broca's area is not affected at all.
VS in left visual cortex lesion:
this lesion is characterized by alexia WITHOUT agraphia.
b/c the lesion affected the corpus collosum which linked the right visual
cortex and left Wernicke area. So it make sense that the patient will have
alexia(cut off from the visual cortex) and NO agraphia (b/c the Broca's area
is intact). | b****5

while the angular gyrus is generally involved in translating visual patterns
of letter and words into meaningful information. |
