Remembrance of rewards past.
Using event-related fMRI, Wittmann and colleagues report in this issue of Neuron that reward value enhances cue memory and that this process is associated with midbrain modulation of hippocampal consolidation. We propose that their findings introduce a novel mechanism by which positive arousal induced by reward anticipation may promote memory.
