Damage to the left parietal lobe can result in what is called "Gerstmann's Syndrome." It includes right-left confusion, difficulty with writing (agraphia) and difficulty with mathematics (acalculia). It can also produce disorders of language (aphasia) and the inability to perceive objects normally (agnosia).
Left parietal-temporal lesions can effect verbal memory and the ability to recall strings of digits (Warrington & Weiskrantz, 1977). The right parietal-temporal lobe is concerned with non-verbal memory.
I guess I'd want to know if I had little time left. It would give one time to make things right.
