The brain structure of adults has been shown to vary with smoking status, particularly in the insula—a part of the cerebral cortex involved in monitoring internal states and decision-making. In a study published in Neuropsychopharmacology, Dr. Edythe London and colleagues took smoking histories, assessed cigarette craving and dependence, and examined the insula using magnetic resonance imaging (MRI) in 16-22-year-old participants. The results suggest that participants with greater smoking exposure had more severe nicotine dependence, more cigarette craving, and less insular thickness than those with less exposure.\"\"/","author_name":"Springer Nature"}
