I am grateful for this video, as the heading is written in bold. Images, and brain scan pic are also in this video. Thank you.

Wow, from 2:22 this is what I do most of the day, unless I am engaged in something, and DMN thought processes tend to distract me from doing things I should be engaged in.

Hi! Great video. I've been having songs "playing" in my mind since I was a teenager. I don't choose to think of them, they simply come, like a background song, sometimes even when I'm actively thinking about something else. Only when I'm speaking they seem to be out of my mind. I've asked doctors and psychologists about this issue but no one's ever heard anything similar. I wonder if it's something related to my DNM. Sometimes I feel tired because my mind can't seem to rest.

How does it relate to ADHD and how can one work around it?

Hey, I’m not a specialist but I have done a lot of research and maybe these findings can help you. The DMN is opposite to the Task Positive Network (TPN) This network activates when we are focused, goal oriented, present, etc. The activation of one network deactivates the other one. In other words, they don’t function at the same time. But this is the difference in people with ADHD. Both networks can’t be properly exchanged and so they can be focused on soemthing (TPN activated) but also be swayed by the distraction caused by the activation of the DMN. The reason this is different in ADHD is because the main molecule in charge of activating and deactivating both networks insist Dopamine (the reward/motivating chemical). This molecule is less present in adhd. The only time people with ADHD can stay focused or even hyper focused on soemthing is when it is naturally soemthing they really enjoy. Only like this can they release enough dopamine for them to stay motivated to keep doing the same activity for long periods of time. My assumption is that you could work around it by finding ways to feel excited about certain activities. Mindfulness/meditation also strengthens the ability to turn off your DMN more easily. Sorry it was so much information. I hope it makes some kind of sense. I tried cramping all the information I’ve gathered. I hope you can make use of it in your personal journey :)

@@aslyngonzalez5923 hi that's very helpful of you to explain in simple terms. Do you mind telling me if there are certain kind of research on this topic. I myself have adhd and want to go for research on this, i am reading about neurofeedback saying it helps but I'm not sure.

@@aslyngonzalez5923 Thats a great information. I came to know about the phenomena of DMN and it has been quite helpful to understand my thought pattern. My mind wanders a lot and I feel I have an overactive DMN. Your info on how this relates to ADHD is game changing and I feel the same case with me. Do you have reference to more resources (Books , Websites , KZbin channels etc) where I can learn more about it ? Thanks.

Is it disrupted in other diseases like Alzhiemers and others?

Does anyone know where "focused visualization" fits in as far as which network is most activated? For example, a basketball player wants to improve his free throws when he can't get to the gym. So, he chooses to focus on visualizing himself at the free throw line, shooting, and making the basket. Although that seems kind of like planning for the future or daydreaming, it's different, and I thought I heard someone somewhere say that kind of focused visualization of a specific actionable outcome actually involves the Task Positive Network and calms or deactivates the DMN.

When the brain is focused, the default mode network is turned off, however what you are explaining sounds like it is more involved in the hippocampus because you are using autobiographical information to visualize it and you are using the medial prefrontal cortex whenever you are making judgements on your shot next time and planning how you will shoot in the future because the medial prefrontal cortex is involved in judgements about yourself and planning

@@wordswithoutwords52 Thanks for your feedback. That makes sense. But also, please share how you feel about the real thing... the basketball player is literally, physically at the free throw line during practice and attempts to make a good free throw. It seems he's really focused on the external world and deeply engaged in it, so that would be the task positive network, yet at the same time of course he's judging himself in wanting to make the ball go into the hoop. I also wonder if, during the visualization, if the person visualizes exactly as he would if it were real, in other words, he's seeing the external would from "inside" his body looking out, rather than visualizing watching himself from a distance. And during that visualization, time goes away and hopes for the future go away, and he's just in that moment making the shot in his mind. I just know that studies have shown that basketball players improved almost as much when they visualized properly as when they literally, physically practiced because they said the mind can't tell the two apart.
