[Default Mode Network] "Idle hands do the Devil's work." Some branch of Christians said that often, which I learned in high school English class. Regardless who said it, it is a very apt description -- some (many?) humans like me have a very prominent thinking capacity and if we are in a depressed mood this idle "monkey mind" (Buddhists I think) becomes an annoying hamster wheel of negative thoughts. Combined with Bipolar Disorder and other "illnesses" it compounds into a pretty bad phenomenon in adulthood. Over time this DMN (or DeMoN(e)) works against us and we need to retrain it. We can redirect the energy in this part of the brain to the physical senses; this is what all contemporary psychologists tell us. Most instruct us to focus on the present; one person actually developed four other methods to retrain/ reframe this network. I will edit this with her name when I find it. Suffice it to say I am working on this.
