    "body_text": "Georgetown researchers scanned volunteers before and after weeks of intensive image categorization. As the skill became automatic, activity shifted away from prefrontal control toward a new category-selective temporal-cortex region; greater offloading tracked better dual-task performance. The result applies to compatible, heavily trained tasks and does not make distracted driving safe.",
