Abstract

Functional resonance magnetic imaging (fMRI) research indicates anhedonia is associated with blunted neural activity during reward-anticipation. However, due to low temporal resolution of fMRI, the time course of these associations remains largely unknown. We leveraged the strong temporal resolution of event-related potentials (ERPs) to examine associations between anhedonia and electrocortical activity across three temporally distinct stages of reward-anticipation: cue-evaluation, motor-preparation, and feedback-anticipation.
