New Study Focuses on Anxiety Disorders

A new study at Stanford University is shedding some light on anxiety disorders, the most prevalent among all psychiatric diseases.

Stanford researchers used light to activate mouse neurons and precisely identify neural circuits that increase or decrease anxiety-related behaviors. The research team, led by Karl Deisseroth, associate professor of psychiatry and behavioral sciences and bioengineering, identified two key pathways in the brain: one that promotes anxiety and one that alleviates it.
