The brains of people with schizophrenia may attempt to heal from the disease

New NeuRA research shows that the brains of people with schizophrenia may attempt to repair damage caused by the disease, in another example of the adult brain’s capacity to change and grow.

Prof Cyndi Shannon Weickert, Dr Dipesh Joshi and colleagues from Neuroscience Research Australiastudied the brains of people with schizophrenia and focused on one of the hardest-hit regions, the orbitofrontal cortex, which is the part of the brain involved in regulating emotional and social behaviour. Most neurons (brain cells that transmit information) are found in tissue near the surface of the brain. However, in the brains of people with schizophrenia, the team found a high density of neurons in deeper areas.

“For over a decade we’ve known about the high density of neurons in deeper brain tissue in people with schizophrenia. Researchers thought these neurons were simply forgotten by the brain, and somehow didn’t die off like they do during development in healthy people,” says Prof Shannon Weickert.

“What we now have is evidence that suggests these neurons are derived from the part of the brain that produces new neurons, and that they may be in the process of moving. We can’t be sure where they are moving to, but given their location it is likely they are on their way to the surface of the brain, the area most affected by schizophrenia,” Prof Shannon Weickert concluded.
