[@kevinwhite6176]

I've made enormous strides in dealing with my anxiety since I learned about this a couple of years ago. I saw something quoting Ethan Kross from University of Michigan talking about how third-person self-talk would suppress the default mode network in people. I started doing it when I would catch myself having these "I'm going to make up a story about how something will happen in the future that isn't pleasant" and suddenly, as soon as I'd tell myself in the third person that I was doing it, it was like someone hit the pause button on something in my brain. That eventually led me to ACT (acceptance and commitment therapy), which is based around "relational frame theory", however I think it dovetails into this whole DMN thing. The DMN is where those negative thoughts are 'coming from' and getting circulated back into when you get stuck in anxiety.

[@barryk7227]

If you happen to have a link to the Ethan Kross material I’d be interested!

[@jind0sh]

Hey I had a similar experience. I also have social anxiety. And one of my strategies when in a social situation is to clearly picture how the interlocutor would see me, my micro expressions, etc, and then sort of emulate how I usually see how a "normal", socially fluent person would act. Picturing myself from a third person pov usually helps take me off my self-conscious tendencies and, like you described, felt like someone hit the pause button on something. Somehow felt lighter on my feet, didn't need to focus too much inwards on how I should act, but on the other person, and this makes everything more instinctual (system 2?). Sort of when watching this video or writing this comment in a cafe, I can feel something definitely paused my everlasting "that person definitely thinks I'm weird, I need to adjust my frozen bitch face" inner voice. So I think I'm starting to get it when Jordan Peterson (I know) said "anxiety is all about where you direct your attention. There is narcissism in anxiety: all you see is yourself. Look outwards, to the dragon's eyes, observe, listen, and you will have something to talk about." I'm wondering whether this is why humans felt the need for religions in a non-engineered, natural way. As an atheist, picturing an all seeing father watching and judging your every move definitely has an effect on one's behavior. Perhaps it plays on these networks on the brain somehow? Because being in a well functioning community like a church (ekklesia: group, congregation, church) needs everyone's self reflection (prayers), participation, clear communication, cooperation; the correct amount of ratio (?) of these two networks? To which, finding the optimal solution to any multivariable ratio is hard enough but the brain is a different beast, it's like everything affects everything. Maybe why these "holy" books are these complicated, self-referencing, long winded collection of narratives (to establish the validity "God"/the "right" structure in oneself) written in hundreds of years by numerous people. I feel like it's unintentionally our earliest pilot massive project tackling this exact behavioral regulation problem. Maybe some people believing these narratives as "truer than true" has to do with how these networks are affected by the narratives. I mean in the bible John said "Jesus is the Word". I looked it up, some say John meant that "Jesus is the physical manifestation of God the Father, just as a spoken word is the physical manifestation of our inner thoughts". But more believe that this establishes the point of faith (Christian at least), which is to believe in the words and act accordingly, to do the "right" thing to others in self-reflection. *I might have digressed, but it feels intuitive because these topics always show up in the same breath. There are people who vehemently believe religions can cure depression, anxiety, and so forth.* Again, not promoting any religion, just making connections that I think is interesting here as an atheist.

This is very interesting stuff and touches on where the self comes from. Perhaps sometime in the future this research may provide answers to how consciousness is produced. Very cool. Thanks for the post!

[@eeveelution8035]

The reason consciousness seems so elusive is that any attempt at explaining it within materialist metaphysics must be either insufficient in explaining how brain activity connects to qualitative experience ('explanatory gap') and/or must silently presuppose consciousness to prove itself*. Also people often mistake consciousness for self-aware behaviour, but consciousness can exist without having a sense of self, the detached self is just a thought. * To demonstrate - let us first assume that conscious experience is 'produced' by arrangements of or interactions between unconscious matter. This is the view that consciousness is an emergent phenomenon. The flaw here is a misunderstanding of emergence. All emergent phenomena require a field of *potential* to *emerge onto*. Notice that these fields of potential exist only within mind, and thus all emergent phenomena are made of thought/feeling. A picture can not emerge from pixels separate from the thought that groups those pixels together. A traffic jam similarly is a mental fabrication, all statements you can make about it - such as how long it exists for - are only ever statements about the thought which groups the cars together. So if we claim consciousness to be emergent, we must necessarily claim that consciousness only exists as a thought/mental fabrication, which leads to cyclical reasoning as we need consciousness to explain consciousness. 21st century conscious research is showing us the limitations of materialism. Finding that consciousness is not produced, but maybe tuned into like a radio signal or filtered like a beam of light, would be much more groundbreaking than finding how it is produced. A metaphysical framework more capable of investigating consciousness moving forward is Analytical Idealism.

[@NadimShaikh-qv7zj]

Have researchers even proved that the self actually exists? Or is it just one of those metaphysical constructs that scientists take for granted?

[@eduardoaraujo8174]

I was constantly on daydreaming mode while I was a kid. When I was on the car my mind was always wandering and loved the ideas that would come out of it. Also I saw things a lot clearer and everything was easier to learn. In my teenage years I tried drugs for the first time and immediately you could tell I was very susceptible to psychosis. One time, very early in my drug carreer (less than 10 joints I smoked in total), I started getting into actual psychosis. I stopped drugs immediately, but I felt like I was always on the edge of having an full strength episode without actually having it. My dmn became scrambles and pretty painfull to experience mentally. I am being treated for that for some years now and while I did not have major episodes I still battle with minor ones constantly. I feel like I am not a quick learner anymore and my dmn is not the same as before. A bit more foggy and devoid of mind wandering experiences . I miss the sharpness of my years before this event although overall I am doing pretty well.

My personal take, as I'm experiencing this "default mode" more and more these days (no drugs involved, rather an "om" phase I'm having), is that the brain is "listening" to a large extent but also "quietly processing" (without any rush nor particular priority).

[@TheSummoner]

Your default mode network is always on without the need for drugs or meditation. Psychedelics and meditation actually shutdown the DMN not boost it up

[@LuisAldamiz]

@@devilsposterboy - I don't think they do. Meditation and default seem to be very similar if not the same thing. Drugs are another story altogether because they "force" your brain to altered and possibly chaotic forms (which may be very interesting at times but not really meditation, something else). In fact meditating on yews under the sun was part of the process of achieving "default".

[@klawiehr]

I was hoping you’d go into psilocybin’s effect on neuroplasticity here :) amazing that the idea of the default mode network is so new

[@brianquigley1940]

Define "nothing". As I understand it, there's two basic types of meditation used to focus your mind. 1. busy meditation, i.e. mantras used to focus the mind. 2. stilness meditation, i.e. shutting off all thought. Form 1 is often used to get to Form 2, e.g. counting breaths. Having practised both, I can tell you that stilness meditation is virtually impossible. Usually, I can minimize the stray thoughts floating around, but it is a very, very rare moment that I find myself floating in that odd state of "no thoughts". And by "no thoughts" I mean no distress due to a physical pain in my body, no verbalizations, no static or moving images, no memories replaying, just a state of awareness of body and nothing else. This state of mind is so infrequent and so "alien" that I immediately pop out of this state of mind. If I'm lucky I can hold that state of mind for some seconds, maybe a minute. Reason? Millions of years of evolutionary survival that created the lizard brain (basal ganglia) and the surrounding mammalian surrounding cortex trained us to always be on the alert and/or preparing for the next crisis.

[@Shockysho]

You are lucky, I can easily remain in that state of ZERO thought, with only a sort of passive awareness of subconscious (beyond my conscious and intentional control) actions like biting my cheek. My struggle is being alert and aware of my external world

[@brianquigley1940]

@Shockysho The "perception" that there is a difference between "external" and "internal" is an illusion. Consciousness and awareness are epiphenomena of our brain.

[@newenglandgreenman]

I do something apparently similar to Form 2, but in fact almost the opposite. I agree that repressing thought doesn't work well. What does work for me is embracing presence and awareness. Don't repress thought. Embrace awareness. Let the sounds and other phenomena around you happen. Focus on your awareness of them. Focus on awareness itself. Instead of rejecting thought, embrace awareness. If an occasional thought pops up, embrace your awareness of that thought. That returns the focus to awareness.

[@brianquigley1940]

@newenglandgreenman Nice. Thanks for the advice. Actually, it's not far off what I already do. Just be aware of it, the thought, or emotion, or physical pain. Just let it be. Just be aware of it. If it's a pain, it fades away. If it's a thought, it dissipates. Usually(!) Being aware of the awareness seems "contradictory", but I get what you mean (I think!).

[@dann_y5319]

Default Mode Network is involved in introspection. Executive Control Network is involved in outward concentration. Saliance network switches between the two. Also, creativity or even a "flow" state arises in the optimal condition where these large-scale neural networks can fluidly communicate, activating and reactivating, enabling you to think and gain insight about a certain task, like when mind-wandering or even after focusing on work in a more restful, imaginative state

I used to have a rich imagination. However I suppose that the DMN in my case is not working properly at all. All it does is to reanalyze events which already happened and worry about mundane life questions. I have basically nothing to dream of and this sucks. I can't understand, what do people do in their life? What they can do? For what? At one time metaphysics slightly helped me to imagine that there is something 'outta there' which is waiting for us. But now I'm not so sure and it doesn't comfort me. I simply see everything as meaningless, and I understand that this is a problem with me.

[@PueMonTen]

The test subjects weren't doing "nothing", they were resting. Resting is doing something. I regularly dive into sensory deprivation so I have the right to this opinion. The brain does not want to be denied sensation so in the absence of that, it will create its own. In doing so, the brain is effectively doing gymnastics. You may be laying down with your eyes closed just simply breathing but a lot of energy is still being used. You can settle brain down and eventually you can reach "nothing" but that is a field apart from this study. I just felt that this was a very important distinction to make

Even more fascinating is that as early as 2500 B.C., the Buddha discovered that the mind creates a thought that masquerades as the self (the ego) and is the root cause of human suffering. In the 20th century, the Indian philosopher J. Krishnamurti explained to the world that the Default Mode Network (DMN) consists of past memories and future projections, as well as the sense of oneself in relation to ideas, people, situations, and so on. He transcended the ego and claimed that anyone who observes and deeply understands these mental processes will be liberated from the ego, and thus from all suffering.

The human body especially the brain is amazing! Not too long ago, I came across a experiment/ study of 2 groups “Control-C & Normal- N” where both groups did the same thing in seven days however the control group was blindfolded “ Don’t remember exactly how, but they were blinded During the experiment” Doing the same basic “everyday” task + more Extensive task “learning braille etc”! Obviously, I’m summing this up but the findings were At First the C Struggled, adjusting to not being able to see. After that almost like unlocking a new sense. The brain no longer had to process visual information, freeing up brain “processing” power! Comparing both groups learning braille, the C learned it relatively quicker than the N group. Along with some other stuff! However, on the last day when the C group regained access to their eyes. Almost immediately the majority of what they learned of braille, faded away. Kind of like the brain needed that space back! I look at the human body as an engineering masterpiece, a machine! The brain is the computer running that machine! The brain has a hard drive “long term memory”, RAM “short term memory” it’s consistently processing a ton of information from all senses! Filtering Information received giving a value to it “relevant, irrelevant, important, Possibly important, garbage etc” kind of like an algorithm “or multiple algo’s” always adjusting learning from new Information! Requiring energy “bioelectric” if its low on power there are issues and if it completely looses power, the HDD & RAM may be corrupted or “almost” completely wiped! From every few days to over a decade “if I remember correctly” your body gets a complete hardware update “growing & replacing new skin, hair, muscle, bone” whilst the brain is constantly making new connections storing data, overwriting older data! Again this is a massively oversimplification, but what logical person wouldn’t think that the body is amazing! Understanding a tiny bit of how one of the almost perfectly engineered biomechines functionality, w/ a brain “computer” to to control & maintain it. Plus its own immune system “antivirus” sleep mode, even when the body or part/ parts of z body is lacking, starved it shuts down parts to preserve the vital, most crucial parts. If it’s overwhelmed with extreme pain causing the person to pass out! It even can over heat! Depending on the environment, habitat, lifestyle, parents genetics and a sh¡t avoirdupois of other variables. Evolving to gain or loose something “up or downgrade” ie the “model” consistently in the sun, hot climates their “shell, case” skin pigmentation will adjust “evolve” to a darker tone better suiting the brutal pounding of that radioactive lamp in our solar system! Millions of years in humanities past, when sky islands existed out of reach. Humans ancestors evolved to have wings “along w/Other things such as 6ft+ long tails” along with more complex brains. Allowing us to dominate those sky Islands, Molding nature to our will forcing said islands back to the earth. Creating great, fisher and cracks upon the massive land surfaces. With a side effect breaking that large single land mass into multiple pieces, slowly separating from each other! Over Millennia Some of that land sunk below the waves, others rose above. So the human body is a advanced being controlled by advanced computer, Perhaps capable of wireless connections “Bluetooth and or Wi-Fi” that been forgotten or gradually used less & less, eventually no longer used leading to have been forgotten. Annndddd if that’s the case then Information would have been transferred the same way between people and something like the cloud “universal consciousness” storing data on a level FB, Goog’s etc would be envious of. Storing each and every experience, thought, emotion, action, Interpretation, outlook, knowledge along with that individual’s unique understanding or lack their of. When the hardware eventually completely fails or gets fatal damaged beyond repair. That energy “consciousness” is transferred in some for or another back to the cloud, absorbed into a pool mixed with all of those billions of consciousness’s that completely the same process and billions that inevitably will! Only for that pool/ cloud to upload a relatively identical average “scoop” of all of that mixed cocktail of consciousness to another human fetus, auto downloading upon reaching a point of assembly when that individual brain goes online. As if it had a BIOS, once the process of all the cells reaching a point of progress during the assembly, enough wiring ran over the frame & through the internals connecting everything to turn on the power, running the necessary parts “organs, blood flow etc” establishing a connection to the brain thus allowing automated control whilst the rest continues to be built. Receiving a lot from its host “z Mum” until reaching a point its able to be removed from the factory. Hopefully without any defects, issues etc. as once it leaves z factory, that’s it! Even though the process isn’t complete, It continues on outside said baby factory. As adjustments are made, parts grown expand with time including z brain. Given it only has Essentially factory settings however, one could argue when z baby’s downloaded Consciousness APK…. Хорошо, я был бы полностью шокирован, если бы вы прочитали все это!

So it sounds like the DMN is a figurative "bridge" or interface between our primal input processing centres (ie. vital sensory inputs for survival) and the conscious ideation levels of our brain. "Doing Nothing" is just a social construct of ideas between people. If we truly "did nothing" we would stop existing because all of our atoms would need to "do nothing" as well :P Thus our DMN continues acting full-time as the distributor between the vital inputs and would explain why psilocybin generates that detached sensory experience. It could also explain our Intuitions. When the DMN interface harmonises our conscious time/ideation/memory centres and unconscious vital sensory functions, we experience a "flow" or "calling" as though being guided by an invisible hand. What some might think of as a spiritual or enlightening experience may simply be a result of this amazing organ COMPUTING THE VERY FABRIC OF REALITY. If for example ADHD is our mind attempting to "boost" our lack of dopamine production via the salience network, then it would explain how performing meditation and exercise would regularly lower this network interruption and allow the DMN to operate more fully for longer periods. I'd be interested if the ADHD tendency to slip into hyperfocus could be at moments when the salience network is 'satisfied' and the DMN facilitates it fully? and then at other times we are in a daydreaming mind fog because other networks are too active and the constant switching between DMN and salient throws us around? Hence why we have no control over moments of hyperfocus and how the disorder can undermine self esteem without external support frameworks.

And you lose all sense of self, you lose the ability to form new (or recall old) episodic memories and connectivity between your major brain regions no longer allows for the kind of mediation essential to a working theory of mind. That’s what happened to me, and despite over a decade of brain scans, dementia tests and studies by eminent UK neuroscientists I am still a long way from recovered.

there was this time that I solved a problem after sleeping. Like when I woke up the solution suddenly came to me and was so obvious.

[@KopyErr]

We need to use the subconscious and stuff more like this :0 I saw a video talking about how powerful the subconscious is It said smth like for example you can say out loud "I want to wake up at 8am" or smth and if you want/mean it then your body will just wake you up I tried to practice it myself, I said out loud "I want to wake up at 11am" I was worried that I would be too tired to even want to wake up if I did wake up at 11am though, but didn't rlly pay that much attention to the thought Then that morning my body did smth weird, it woke me up from like 8am every hour untill 11am 💀 Maybe they were trying to make it easier for me to wake up :o But anyways I love that we can use our subconscious, it's a superpower A second brain Not talked about enough I should probably research and test it, it's absolutely phenomenal

[@lunapam2447]

@@KopyErr That wake up thing is real. I tried that. after sunmer, first day of college, I had to wake up early. So I set my mind to wake up 8 AM, I was also afraid to be late. So what happend was I woke up at 7:30 much more earlier than the alarm. This was unusual because I usually wake up 10:00 Am in the summer hahaha. it was weird because I did not feel sleepy or anything, My eyes just opened and I woke up exactly before 8 AM, this was before the alarm.

I wonder how ADHD might affect the default mode…

[@liam78587]

"It sounds like you're interested in how ADHD (Attention-Deficit/Hyperactivity Disorder) might impact the default mode network (DMN) in the brain. The DMN is a network of interacting brain regions that is active when a person is at rest and not focused on the outside world, like when daydreaming or thinking about the past or future. In individuals with ADHD, research suggests that the DMN behaves differently compared to those without ADHD. Here are some key points: Impaired Switching: In people without ADHD, the brain switches efficiently between the DMN and other networks, such as the task-positive network (TPN), which is active during focused, goal-oriented tasks. In ADHD, this switching is often less efficient. This can lead to difficulties in sustaining attention on tasks, as the DMN might remain more active even when focus is needed. Overactivity of DMN: Some studies suggest that the DMN may be more active in individuals with ADHD, even when they are trying to focus on tasks. This overactivity might contribute to the distractibility and mind-wandering often seen in ADHD. Functional Connectivity: The connections between different regions within the DMN might be altered in ADHD. This could affect how different parts of the brain communicate during rest and how the brain transitions between different states of activity. Developmental Differences: The DMN typically undergoes significant changes during development, and these changes might be different in individuals with ADHD. This could contribute to the persistence of ADHD symptoms as a person grows older. Overall, these differences in the DMN could help explain some of the core symptoms of ADHD, such as inattention, distractibility, and difficulties with executive function. The relationship between the DMN and ADHD is an active area of research, with ongoing studies aiming to better understand these neural dynamics." chatgpt

Caltech discussed the kind of signals processing eyes do in the Retina, heterodyne transmission of wave-packaging formation. The period doubling of default frequencies, alpa, beta, gamma and delta suggest that math-music type harmonics and counterpoint plagel integration are occurring in a to-be-expected probabilistic/logarithmic pattern of brainwaves functioning according to neurological interference positioning-location in the Singularity-point Aether of Mind-Body QM-TIME Completeness Actuality.

[@1MoreWin]

I’m confused.. how is there ever a quiet moment in anyone’s mind? I haven’t had a single second of silence from my thoughts for every second I’ve been conscious, atleast from 5-6 years old.. I typically have a half dozen thoughts running simultaneously, I will both daydream and decide whatever situation I am in from multiple perspectives. It’s mentally extremely extremely exhausting keeping track of it all and I have no ability to turn these thoughts off, they occur naturally for me atleast?.. My mind is constantly running and I’ve always been completely aware of my subconscious “daydreaming”. Is this not normal? Maybe I have ADHD. Idk

[@anywallsocket]

What is the 3rd network? There’s clearly intro and extrospection…

[@brianquigley1940]

These "systems" are just approximations in an attempt to build a model. You can strip away parts of the mammalian cortex, and the basal cortex will still keep our body alive. What "systems" have been stripped away? People that lose one half of their brain can still learn new skills... where are the "systems"?

[@Milkshakman]

One of the most interesting fallacies of human experience is that we can feel like we're not doing much whilst embedded in oceans of counterfactual mental constructs. What I don't understand is why there is typically a felt resistance to less counterfactual depth. Perhaps because you think if you go too far in that direction, you will be annihilated?

[@vladyslavkorenyak872]

Because only the counterfactuals that impact your reproduction success are being brought naturally to your attention. The brain actually does not care about logical coherency, it did not evolve to.

[@thwartificer]

What do you mean by counterfactual?

[@Milkshakman]

@@thwartificer "As soon as one is ‘away’ from the present moment, one has made an ‘abstraction’. For example, there are the wavelengths of light that represent the shape of a ‘teacup’. However, once it has been conceptualized as a teacup, there is a new level of abstraction that demands further inference from past experience than simply representing the wavelengths of light (i.e., more temporally deep processing). And yet, experiencing a ‘tea cup’ first necessitates the representation of the wavelengths of light contacting the retina (thus, hierarchical processing)." - Laukkonen & Slagter (2021) So a "counterfactual" here could perhaps be considered informally synonymous with "conceptual construction", in the sense that the construction is 'counterfactual' to the constituent parts that lead to its emergence. I recommend that paper for further discussion.

I would really love for a neuroscientist to help me understand what "envisioning" in your mind means. I have Aphantasia and I have been stuck on what imagination must look like but also if it isn't something I can see with my eyes then where is this imagery I'm told everyone can see but not see??? I know it's not debilitating, I function 'normally' to everyone else but the concept of imagination has made me question quite a lot in the past 3 years. Also just to make sure the question is worded correctly, I do not mean the parts of the brain that are active when imagining. I am asking where these images manifest to become something perceivable.

This is probably only me bit I have always found the phrase "my brain" a very odd one. As if it is someone else. We are our brain to all intents and purposes. It's like someone who refers to themselves in the third person. "I" and "my brain" is the same thing. The only time I would make a distinction is when referring to unconscious things the brain is doing, but even then I would just say "unconscious." The amount of times I hear people say things "my brain is confused, I just want it to sort this problem out" or something like that, almost like blaming a third party. What they really mean is they are not smart enough 😂
