Gray matter loss in schizophrenia
WebGray matter loss in the cortex is extensive in schizophrenia, especially in the prefrontal-temporal-network (PTN). Several molecules such as neuregulin-1 (NRG1) and its ErbB4 receptor are encoded by candidate susceptibility genes for schizophrenia. The question arises as to how these genes might contribute to the observed changes in gray matter.
