DMN: “if nothing else is happening, this is where you are”.
I do not have major depressive disorder.
Seeing how the “default mode network” when it is strongly connected to the areas where depression happens seems to cause the continuous negative “rumination” (a great word I so rarely see) found in major depressive disorder, is helping me analogize to myself where the “default mode network” links to.
So for example, music continually composing in my head may be a “default mode network” operation, similar to rumination in major depressive disorder. So DMN is basically “if nothing else is happening, this is where you are”.
