In a first-of-its-kind study, researchers have determined the underlying anatomical cause of certain symptoms of schizophrenia, then ameliorated them with non-invasive brain stimulation. The scientists reported that these symptoms arise from a breakdown in a network between the brain's prefrontal cortex and the cerebellum, and that non-invasive brain stimulation restored network function, which in turn improved schizophrenia's most debilitating symptoms.
