Scientists at Imperial College London have been comparing samples of brain tissue donated by people with and without schizophrenia. They analysed 51 samples altogether, 28 of which were from people with schizophrenia. The study found 49 genes that worked differently in people with schizophrenia, many of them involved in the chemical signalling between brain cells. The research suggests that abnormalities in the way in which cells signal each other are involved in the development of the condition.
