Default mode network and theory-theory

Continuing some recent posts (like this one), I appreciate this article from the Journal of DCN, how developmental psychology and social neuroscience can work together. Concerning theory-theory, it suggests that our "default mode network, a coordinated network that is activated by task-independent introspection or self-referential thought," might be critical to support it. It involves several brain regions connected in a cohesive network, which seems more like 'supramodal space,' although they didn't use that expression.
