Very exciting news! Our first preprint has made it to its final published form in the Journal of Neuroscience.
In our new work, we report evidence for a 6–12 Hz theta rhythm that is generated by the medial frontal cortex (MFC) and synchronized with ongoing consummatory actions. Previous studies of MFC reward signaling have inferred value coding upon temporally sustained activity during the period of reward consumption. Our findings suggest that MFC activity is temporally sustained due to the consumption of the rewarding fluids, and not necessarily the abstract properties of the rewarding fluid. Two other major findings were that the MFC reward signals persist beyond the period of fluid delivery and are generated by neurons within the MFC.
