A maniacal grizzly bear impersonator resects portions of your right cerebral cortex, specifically, your posterior superior temporal sulcus and dorsolateral Frontal Cortex.

ANSWERS AND EXPLANATIONS
A) Gerstmann syndrome
This answer is incorrect.
Gerstmann syndrome (a constellation of dysgraphia, dyscalculia, finger agnosia, and left-right confusion) is associated with lesions in the dominant hemisphere near the angular and supramarginal gyri. A lesion of the posterior superior temporal sulcus and dorsolateral Frontal Cortex would not produce Gerstmann syndrome.
