A deletion on human chromosome 22 (22q11.2) is one of the largest genetic risk factors for schizophrenia. Mice with a corresponding deletion have problems with working memory, one feature of schizophrenia. It is now found that these mice also show disruptions in synchronous firing between neurons of the prefrontal cortex and of the hippocampus, an electrophysiological phenomenon that has been linked to learning and memory and which is also thought to be disrupted in schizophrenia patients.
