Research Overview

The goal of this team is to elucidate the causes of bipolar disorder to develop new treatment and diagnostic methods. Elucidating the neurobiological basis of bipolar disorder will change clinical practice of depression and will lead to understanding molecular neurobiological basis of mood regulation. We are taking an approach to analyze animal models as well as clinical samples including cellular models and postmortem brains using advanced technologies of genomics or neuroscience. Currently we are also focusing on the roles of paraventricular thalamic nucleus in mood disorders.
