Failure to deactivate in autism: the co-constitution of self and other

A new brain imaging study demonstrates that patients with autism have a strikingly different pattern of brain activity compared with control subjects. During cognitive tasks, cortical areas known as the 'default state' network - areas that have been implicated in both self-referential processing and processing of socially relevant information - typically reduce their brain activity. In patients with autism, such a reduction was not observed. This new finding indicates that a core deficit in autism might be related to the construal of a sense of self in its relationship with others and will certainly generate exciting new research on the neurobiology of autism.
