Fig. 1 Summary of this research (IMAGE) Osaka University Caption The problem in this research field(left) and approaches to address the problem (center, right) are described. In this study, we developed a fluorescent sensor for real-time measurement of brain oxytocin dynamics in living mice. This new tool will pave the way for the elucidation of how oxytocin acts on the brain during a variety of biological processes.
