It has recently been demonstrated that in nicotine-deprived smokers, reward and attention circuits are reactivated by mere exposure to smoking-related images, in contrast with neutral images (Due et al., 2002). In our experiment, prior to stimulation onset 14 'neutral' or 'nicotine-related' colored photographs will be presented on a computer screen to the participants while there are seated. The 'nicotine-related' photographs will be composed from smoking-related scenes, such as lighting up a cigarette, smoking puffs etc. 'Neutral' photos will consist of matched pictures without any nicotine related content (e.g. inanimate objects, hands, faces etc.). As the investigators have previously shown with the figure-8 coil experiment, there was a stronger effect of the rTMS treatment in subjects exposed to the nicotine photographs. The investigators propose that presentation of the nicotine photographs causes the nicotine-related memories to become activated and therefore, labile for interference, as previously has been shown (Dudai, 2004 ).
