Sometimes negative results are also beautiful.

Our key idea: We haven't been looking at these responses the right way. Serotonin neurons aren't (only) activated by current reward, they're (mainly) activated by changing expectations of reward in the future!
We call this a prospective code for value.

Come hear about our new re-analysis of a free reward consumption experiment from the Minmin Luo lab, and how heterogeneous discounting might fit in! 2/3

What makes serotonin neurons tick?
Stop by #COSYNE2025 poster 1-116 on Thursday to hear about how an energy-efficient code for value explains the in vivo responses of serotonin neurons to rewards and punishments. 1/3
