...strokes, brain tumors and other neurological conditions. But as the technology has become more sophisticated, researchers have started to employ it to tease out some of the subtle changes associated with mental illness. "We're not yet able to use these scans in a diagnostic way," says Dr. David Silbersweig of the Weill Cornell Medical College in New York City. "But we're getting pretty specific about the areas of the brain that are implicated in a number of psychiatric disorders...
...article published last week in Nature, a team of U.S. and British researchers report that they have pinpointed brain circuits that seem to control the auditory and visual hallucinations of schizophrenia. "We've identified the areas that are responsible for the brain creating its own reality," says neurologist David Silbersweig at New York Hospital-Cornell Medical Center. "This may help us tailor the medications...
...research suggests that hallucinations are jointly generated by the brain's deep structures that regulate thinking and emotions and surface regions that process sights and sounds. Silbersweig says that by integrating fleeting voices and visions with emotions, the schizophrenic brain may give these simulacra an acute sense of reality.
