Scientists have found boys with autism have larger-than-average brains with more neurons in the prefrontal cortex, the part linked to social relationships and communication.
It is significant because neurons in almost all brain areas are generated before birth.
If confirmed, this makes it less likely that environmental factors after birth, such as vaccination, could be implicated in autism.
