Researchers at NORMENT and University of California San Diego (UCSD) have found a link between six different gene variants and certain personality traits. Further, specific gene variants seem to influence both personality traits and psychiatric disorders such as schizophrenia and bipolar disorder. The results are published in Nature Genetics.
The English newspaper Daily Mail has described a study conducted at NORMENT, which suggests that schizophrenia may be a by-product of the complex evolution of the human brain.
