- Substance cues (e.g. pictures of drug use) make an important contribution to low abstinence rates of drug users by triggering strong craving or habitual behavioral tendencies. Among other things, a strong neuronal response to substance cues is a predictor of high consumption and relapse probability. One possible mechanism is that the processing of substance cues interferes with the implementation and maintenance of self-regulation and goal-directed behavior. The aim of the study is therefore to investigate to what extent substance cues (cigarette pictures) influence the performance of smokers in two tasks (working memory and behavioral inhibition) and to identify the neuronal correlates of this process. It is assumed that the presentation of substance cues versus neutral images leads to impaired performance in these tasks, which is associated with an increase in the activity of subcortical (e.g. ventral striatum, amygdala) and a decrease of frontal (e.g. dorsolateral prefrontal cortex, inferior frontal gyrus) brain regions.
