Damage to left hemisphere region commonly associated with reading and language processing is which area?

• A. Angular Gyrus
• B. Supramarginal Gyrus
• C. Heschl's Gyrus
• D. Occipital Lobe

Answer: (A)

The left angular gyrus sits where the parietal, temporal, and occipital lobes meet and is key for translating visual word forms into language meaning. When this area is damaged, the ability to read and connect written text to language breaks down, leading to difficulties like alexia and agraphia. This makes it the region most directly linked to reading and language processing in the left hemisphere.

Heschl's gyrus is the primary auditory cortex, so damage there would disrupt hearing rather than reading. The occipital lobe handles general vision. The supramarginal gyrus supports phonological processing in language, but the angular gyrus is the strongest link to reading and semantic integration, which is why it’s the best answer.
