The article reports that researchers at the Stanford University School of Medicine have identified one unifying principle that could explain how a variety of causes and treatments for depression converge. Their findings, which were published in the July 2007 edition of "Science Express," found that in rats, the differing mechanisms of depression and its treatment in the end appear to funnel through a single brain circuit. Changes in how the electrical signals spread through the circuit appear to be the cause of depression-related behavior. The author reveals that because the brain is essentially a complex electrical circuit, researchers set out to test whether brain circuitry malfunction is at the root of depression.
