Researchers discovered that six psychiatric disorders seemed linked to the same underlying brain wiring.

Scientists have uncovered a mysterious network of brain connections that is linked to several psychiatric disorders, including schizophrenia, depression and obsessive-compulsive disorder .

In total, the study identified six disorders — schizophrenia, bipolar disorder, depression, addiction, OCD and anxiety — that share this underlying circuitry, and"we suspect that other psychiatric disorders may also be linked to the same network," said Taylor, who is also an associate psychiatrist at Brigham and Women's and an instructor in psychiatry at Harvard Medical School.

Named for its color, the brain's gray matter is made up of the bodies of brain cells, or neurons, and the uninsulated wiring that extends from those cells. Gray matter is found in the wrinkled outer surface of the brain, the cerebral cortex, as well as in some structures beneath the cortex.—What the folds of your brain could tell you about schizophrenia riskThe team pinpointed brain regions where gray matter had atrophied, or shrunk, in the context of psychiatric disorders.
