- The DMN allows for expansive, imaginative, and creative thinking.
- The back half of the DMN — called the posterior cingulate — facilitates your autobiographic memory, and your personal history.
- This allows you to think back, draw upon, and pick apart the past.
- The front part, the medial prefrontal cortex, is the opposite. It enables you to look forward and to think about, imagine, and plan for the future.
- In the DMN mode you can daydream or make interesting connections between concepts.
- People with ADHD or VAST often get stuck in the DMN, leading to horribly negative, gloomy, and self-critical thoughts.
