Furthermore, we found that in people who intentionally mind wander, two main brain networks broadly overlap each other: the default - mode network, which is active when focusing on information from memory, and the fronto - parietal network, which stabilizes our focus and inhibits irrelevant stimuli as part of our cognitive control system.»

This suggests that the default mode network could be responsible for our sense of self.

A network of interacting brain regions known as the default mode network (DMN) was found to have stronger connections in adults and children with a high risk of depression compared to those with a low risk.

The results, published in 2015, showed that the drug - induced religious mindset was due to a change in activity in the default mode network — a region associated with how we relate information about the world to ourselves.
