In this research project, the aim is to discover the role specific brain networks play in the relationship between stress reactions and the desire for alcohol and alcohol consumption. To investigate this question, various brain imaging methods as well as cognitive tasks are combined. Various questionnaires are sampled and brain scans are conducted.
