Neuroimaging technology has provided unprecedented opportunities for elucidating the anatomical correlates of major depression. The knowledge gained from imaging research and from the postmortem studies that have been guided by imaging data is catalyzing a paradigm shift in which primary mood disorders are conceptualized as illnesses that involve abnormalities of brain structure, as well as of brain function. These data suggest specific hypotheses regarding the neural mechanisms underlying pathological emotional processing in mood disorders. They particularly support a role for dysfunction within the prefrontal cortical and striatal systems that normally modulate limbic and brainstem structures involved in mediating emotional behavior in the pathogenesis of depressive symptoms.
