We’ve posted quite frequently about mind-wandering on this blog (here, here, and here — to pick just a few). This post introduces a comprehensive article about the brain activity that correlates with various mind-wandering states.
As John Leiff (M.D.) notes, when you just lie still and think about nothing in particular, your brain isn’t quiet; a well-defined set of neural networks is firing. This group is called the Default Mode Network (DMN, or DN), and it has gotten a lot of research love in recent years.
Lieff’s article explores — in detail — the relationships between different parts of the DN and different kinds of mind-wandering and meditation.
This comprehensive review doesn’t offer any immediate teaching implications. However — and this is a big however — if you’re interested in mindfulness, and want to use brain research to make you case to your admin team, you will benefit from knowing the information that Lieff offers you here.
