1. Several brain regions have been found to respond differently to information relating to the self than they do to information relating to others, even to very familiar others. For instance, such regions may be more active when people think about their own attributes than when they think about the characteristics of other individuals. These regions could be part of a self-network.
2. The sight of someone being touched made her feel as if someone were touching her in the same place on her own body. She thought everyone had that experience.
That last one is a real kicker - apparently our brain has to learn how to differentiate what is "self" and what is "other", and some people get it wrong!
Of course, as a Buddhist, I am convinced…
