Switching between tasks in cue-based decision-making has been studied intensively, e.g. putting on hold one task while performing another one, with a fixed reward. Here, the frontopolar cortex (FPC) is engaged when subjects are required to keep in mind a main goal while performing parallel subgoals, and the anterior cingulate cortex (ACC) associates actions to outcomes. During my thesis, I investigated switching on different levels of action abstraction in value-based decision-making: choosing freely on the one hand between two simple actions, and on the other hand between two abstract structures, i.e. competing tasks. fMRI BOLD signals were recorded on healthy subjects during a probabilistic reversal-learning para-digm, with anti-correlate...
