How does mindfulness meditation impact DMN activity?
Mindfulness meditation is a practice that aims to cultivate present moment awareness, often by focusing attention on an external object such as the breath or bodily sensations. This practice has been shown to affect Default Mode Network (DMN) activity in several ways.

Research conducted by Zeidan et al. (2013) showed that after just 8 weeks of mindfulness meditation training, individuals exhibited a decrease in DMN activity during a resting state and while performing an attentional task. This suggests that mindfulness meditation could potentially reduce the tendency of the brain to default into self-referential thinking or mind-wandering.

Furthermore, another study by Tang et al. (2015) showed that mindfulness training increased connectivity between the DMN and regions associated with attention control, implying that meditation may help to integrate the DMN more effectively into goal-directed tasks. This could result in better focus and concentration during daily activities.
