Brain Research on Mood

Your mood affects how you react to daily events, and how you react to daily events affects your mood. We want to understand the details of the two-way connection between mood and reactions to good and bad events. We hope this will help us better understand why people with certain mental disorders have persistently low or unstable mood.
