Smokers typically undergo well-characterized emotional and physical withdrawal symptoms that make quitting extremely difficult However, N. effortlessly quit smoking immediately after his stroke and never relapsed. He told doctors, "My body forgot the urge to smoke."

Bechara says, "What is striking is that it was as if a switch had been turned off--he quit just like that, without any effort at ally

They spotted damage in the insula, a region deep inside the cerebral cortex. The insula had previously been associated with monitoring the body's internal conditions and controlling conscious urges, such as the desire to eat.

The researchers next identified 69 smokers or former smokers with a variety of damaged brain areas caused by strokes, surgery, or other factors. Nineteen of these patients had damaged insulas, and all had quit smoking. …
