Research Summary

Why do we eat even when we are not hungry? Consumption behaviors can be well triggered not only by the homeostatic need but also by pleasure. While hunger neuronal circuits have been extensively studied recently, but the neural mechanisms which are responsible for overeating and how to control them to reduce binge eating are not clear. To explore it, I combine electrophysiology, optogenetics and quantitative behavior analysis to investigate how the motivations for meeting the homeostasis and seeking rewards shape the higher brain functions to further influence binge eating behavior.
