Your brain has a default mode network (or DMN) that comes online when you're not concentrating on anything.

你的大脑有一个默认模式网络（或称 DMN），当你不集中注意力时，它就会上线。

It's thought that the DMN helps us retrieve memories, think about the future, and understand the thought processes of other.

人们认为，默认模式网络帮助我们检索记忆，思考未来，并理解他人的思维过程。

When you practice being mindful of the present, such as when you focus on your breath, the DMN quiets down.

当你练习专注于当下时，比如当你专注于呼吸时，默认模式网络就会安静下来。

Studies show that with greater mindfulness practice, an individual can gain greater control of the DMN and get better at keeping it quiet and thus be more attentive in the present moment.

研究表明，通过更多的正念练习，一个人可以更好地控制默认模式网络，并在让其保持安静方面做得更好，从而在当前时刻更加专注。
