Behavioral flexibility enables us to tailor actions to the ever-changing demands and constraints of our environment. Different regions of the prefrontal cortex, such as the orbitofrontal cortex (OFC) and the medial prefrontal cortex (mPFC), are known to be differentially involved; yet, their complementary roles in behavioral flexibility remain unclear. In order to dissect their relative contributions, we developed a reversal learning task using Freibox, a custom-built, open-source platform for behavioral experiments. Reversal learning performance in this task depends on the OFC, which we demon

Freedom of choice enhances the sense of agency over the outcomes of our actions and has been suggested to benefit experiential learning. Yet, how agency experience influences the neurophysiological processing of feedback during goal-directed behavior is not clearly understood. We performed two EEG studies to examine how freedom of choice influences feedback processing during reinforcement learning. Participants received performance feedback in form of monetary gains and losses following binary item choices by the self or the computer. Study 1 (N = 30) revealed augmented feedback-induced midfro
