A patient named Sally recently suffered a stroke that damaged her right parietal lobe without affecting other parts of the brain. The left side of her body¿controlled by the right hemisphere¿was paralyzed. But she was mentally normal and continued to remain the talkative, intelligent woman that she was before the stroke.
Yet Sally¿s father observed other disturbing symptoms to which¿oddly enough¿Sally herself seemed oblivious. When she attempted to move around the room in her wheelchair, she would sometimes bump into objects on her left.
