How has scientific research linked DMN to mind-wandering specifically?
Studies have shown that the Default Mode Network (DMN) is particularly active during self-referential thinking or mind-wandering, which is a state of mind where our thoughts drift off to unguided internal reflections rather than staying focused on the external task.

One study by Mason et al. (2007) found that the DMN's activity increased when participants were asked to let their minds wander, and decreased when they focused on an external task. This suggests a strong link between DMN and mind-wandering.

Moreover, another study conducted by Christoff et al. (2009) showed that the degree of mind-wandering in daily life was associated with the strength of functional connectivity within the DMN. Stronger connections within the DMN were linked to higher rates of mind-wandering.
