Brain pattern behind bad mood identified
Scientists have identified a common pattern of brain activity behind bad mood, an advance that could help develop new therapies for depression and anxiety.
Most human brain research on mood disorders has relied on studies in which participants lie in an fMRI scanner and look at upsetting images or listen to sad stories.
These studies have helped scientists identify brain areas associated with emotion in healthy and depressed individuals, but they do not reveal much about the natural mood fluctuations that people experience over the course of a day or provide insight into the actual mechanisms of brain activity underlying mood.
Researchers identified a common pattern of brain activity that may be behind feelings of low mood, particularly in people who tend towards anxiety.
