Quite interesting - I wonder how I can find a test for this part..

The ventromedial seems to be the differing part:

"the magnitude of neural self-other distinction in ventromedial prefrontal cortex was strongly related to the
magnitude of early childhood social impairments in autism. Individuals whose ventromedial prefrontal cortex made the largest
distinction between mentalizing about self and other were least socially impaired in early childhood, while those whose
ventromedial prefrontal cortex made little to no distinction between mentalizing about self and other were the most socially
impaired in early childhood. These observations reveal that the atypical organization of neural circuitry preferentially coding
for self-information is a key mechanism at the heart of both self-referential and social impairments in autism."

Preferential coding... interesting!
