They found a lamentable correlation: The greater a teens addiction to nicotine, the less officious the anterior cortex was, suggesting that smoking can walk erupt brain function. The research appears in the current online edition of the account book Neuropsychopharmacology. The finding is obviously not good news for smokers, hold the studys senior author, Edythe London, a prof of psychiatry at the Semel bound for Neuroscience and Human Behavior at UCLA.

As the anterior cortex continues to develop during the critical completion of adolescence, smoking may rent the trajectory of brain information and affect the function of the prefrontal cortex, London said. In the study, 25 smokers and 25 non-smokers between the ages of 15 to 21 were asked to perform a test that activated the prefrontal cortex and required them to curtail responding.
