PAIN

A common ground for pain and depression

Chronic pain is associated with anxio-depressive comorbidities, but the neuroanatomical substrates remain unknown. A specific serotonergic pathway from the dorsal raphe nucleus to the lateral habenula via the central amygdala is now uncovered as a key neural circuit governing comorbid depressive symptoms in chronic pain.
