- In a neurotypical brain, when the TPN is turned on and you’re on task, the DMN is turned off.
- In the ADHD brain, the fMRI shows that when the TPN is turned on, the DMN is turned on as well, trying to muscle its way in and pull you into its grasp, thereby distracting you.
- Therefore, the DMN competes with the TPN, which in most people it does not do.
- When trapped in the past or future in the DMN, you’re likely to abandon projects you once started with enthusiasm, make careless mistakes, or, worse, fall into a state of misery and despair, for no good reason whatsoever.
