Health: they stop smoking suddenly after a stroke, researchers find out how to stop tobacco addiction by manipulating the brain

An evil for a good? A study reveals that brain damage causes the end of tobacco dependenceas reported by our colleagues from TV3.

Des chercheurs americans et suédois have published the results of their work in the journal Nature Medicine. They observed patients who had a sudden urge to quit after a stroke and noticed that these had lesions in at least one of the three areas of the brain namely the dorsal cingulate, lateral prefrontal cortex, or insular cortex.

The researchers concluded that there was one brain circuit responsible for addictions. In contrast, no lesions were detected in the cortex medial prefrontal cortex, suggesting that it blocks dependence.
