Feedback-Related Negativity

Although we know a lot about the neural regions which are involved in decision making, little is known about the temporal signatures of decision making and learning. In this study, we investigated the Feedback-Related Negativity, an event-related response of the EEG which has been proposed to reflect reward prediction errors. We used simultaneous EEG-fMRI to study the FRN in more detail. We investigated whether the FRN reflected prediction errors or saliency signals, determined the neural source of the FRN using the concurrently aquired data, and studied the organisation of the network using dynamic causal modelling (DCM).
