What is the Default Mode Network (DMN)? How does it relate to our daily mental activities?
The Default Mode Network (DMN) is a group of interconnected brain regions that typically show increased activity when an individual is not engaged in goal-directed tasks. These regions include the medial prefrontal cortex, posterior cingulate cortex, the precuneus and the angular gyrus among others. DMN's functions are quite diverse, including self-referential processing, introspection, memory consolidation, and mind-wandering.

In our daily mental activities, DMN plays a significant role in<dummy00008> when we're not actively focusing on the outside world. For instance, it tends to be more active during rest, daydreaming or even meditation. This network is also implicated in rumination, which is repetitive thought about oneself and one's circumstances.
