If one’s ventricles are large compared to what is normal for a brain of a particular size, that means that there is less functional brain tissue. Butcher, S. Mineka, and J.M. American Experience,"Transcript." The brain abnormalities found so far are non-specific and can also show up on people with quite different disorders, for example people with other psychiatric disorders such as schizophrenia. Garrison, also a member of the psychology department, said the investigators think "PCS is involved in brain networks that help us recognize information that has been generated ourselves."

Non-invasive brain imaging techniques such as Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT), have documented structural differences between normal brains and those with schizophrenia. Study leader Jon Simons, a neuroscientist from Cambridge's psychology department, said, "Schizophrenia is a complex spectrum of conditions that is associated with many differences throughout the brain, so it can be difficult to make specific links between brain areas and the symptoms that are often observed.
