In the 1st FP we developed an experimental and statistical framework that allows to formally model and validate reward and aversion discounting, and to identify their underlying neurobiological mechanisms in human fMRI and animal experiments. In the 2nd FP we aim to investigate these specific cognitive processes for their individual and combined contribution to addiction. By an iterative experimental approach, we will identify the most relevant processes by computational modeling of observed behaviors and then examine their underlying mechanisms by fMRI. We further hypothesize that core regions of behavioral control are comparable between humans and animals. Therefore, in rats we will characterize the neuronal activity and connectivity patterns expressed during specific discounting behaviors and identify neural trait markers of discounting behavior.
