متن کاملPrenatal Exposure to Maternal Cigarette Smoking and Adolescents’ Reward Processing
Introduction Previous neuroimaging studies demonstrate that drug addiction is characterized by altered reward processing. For example, smokers show an increased reactivity to drug related stimuli in the reward circuitry compared to non-smokers (Due et al., 2002). On the other hand they demonstrate a decreased neural response to non-drug rewards in these areas (Bühler et al., 2010). Animal studi...
