Increased connectivity between DMN and executive control regions following mindfulness training could underlie increased capacity for volitional shifting of attention. The increased PCC-DLPFC rsFC following MBET was related to PTSD symptom improvement, pointing to a potential therapeutic mechanism of mindfulness-based therapies.

Major depressive disorder (MDD) affects multiple large-scale functional networks in the brain, which has initiated a large number of studies on resting-state functional connectivity in depression. We review these recent studies using either seed-based correlation or independent component analysis and propose a model that incorporates changes in functional connectivity within current hypotheses of network-dysfunction in MDD. Although findings differ between studies, consistent findings include: (1) increased connectivity within the anterior default mode network, (2) increased connectivity between the salience network and the anterior default mode network, (3) changed connectivity between the anterior and posterior default mode network and (4) decreased connectivity between the posterior default mode network and the central executive network. These findings correspond to the current understanding of depression as a network-based disorder.
In 1992 the Dalai Lama offered neuroscientist Richard Davidson, founder and director of the Center for Investigating Healthy Minds at the University of Wisconsin-Madison, the opportunity to scan brains of Tibetan monks to learn if years of cultivating well-being created changes in the brain. The monks had lifetime practices of mindfulness meditation with focus on compassion and loving kindness. Their functional MRIs showed very well-developed insula, the region of the brain that is activated by focus and attention on the body and on feelings. This finding also extends to the brains of those who have training in Mindfulness Based Stress Reduction, a program designed by Jon Kabat-Zinn (Davidson and Begley 2012).
