SallyHOST
It keeps you safe and grounded in daily life, letting your brain know where your body ends and the outside world begins, so you can manage your basic physical needs, protect yourself from harm, plan your day, and navigate your relationships without constantly feeling overwhelmed or scattered.
SallyHOST
The Lifespan Assembly, the Triple Network Model This evolutionary architecture is mirrored in the lifespan of every human child through the sequential maturation of the triple network model consisting of One, the narrative self-talk storyteller, known as the default mode network, DMN.
SallyHOST
Two, the action-oriented executive task manager, known as the central executive network, CEN.
SallyHOST
Three, the brain's internal traffic switchboard, known as the salience network, SN.
SallyHOST
Infancy 0-18 months, attachment and the unintegrated state.
SallyHOST
Functional neuroimaging reveals that the triple network model is largely offline and unintegrated during infancy.
SallyHOST
The DMN is structurally fragmented and long-range white matter tracks lack the fatty myelin insulation needed to connect distant brain regions efficiently.
SallyHOST
concurrently through repeated patterns of interaction with primary caregivers, grounded in the framework established by psychoanalyst John Bowlby in his 1969 work Attachment and Loss, and later expanded empirically by Mary Ainsworth in her 1978 observational Strange Situation Protocol.
Rebecca ChabotHOST
Perhaps if we're still trying to catch up, so to speak, from sleep.
Rebecca ChabotHOST
So there's something interesting that you guys might not yet know, and that is that when we are bored, the brain switches on to what's known as the default mode network.
Rebecca ChabotHOST
Do you know about the default mode network? So this is the part of the brain that is self-referential.
Rebecca ChabotHOST
And it actually switches on when we are actually bored.
Rebecca ChabotHOST
So not when you're watching Netflix, not when you're having a conversation with a friend, not when you're listening to music, although potentially, but probably less.
Rebecca ChabotHOST
Or it could be long term, what you did years ago, you know, what happened when you were a child.
Rebecca ChabotHOST
And then also thinking into the future long term in that kind of, you know, drifty type of way.
Rebecca ChabotHOST
So So the default mode network of the brain is really important.
Jessica McCabeHOST
That's a thing.
Jessica McCabeHOST
This is thanks to how the Default Mode Network, or DMN, works differently for those of us with ADHD, which you can learn more about in this video.
Jessica McCabeHOST
I was once anxiously talking through a scenario that was at least two years down the road when my therapist interrupted to ask, what's happening today? I was confused and kind of annoyed.
Jessica McCabeHOST
Today is fine.
Jessica McCabeHOST
Listening to a friend can be more engaging and possibly easier to focus on if you do it while being active, like on a walk or while jogging together, or if the weather outside is frightful, take turns decorating your tree or baking cookies together, something indoorsy.
Jessica McCabeHOST
When we make an activity active instead of passive, it forces the task-positive network.
Jessica McCabeHOST
in our brains to engage and dampens the default mode network, DMN, making it easier to be present.
Jessica McCabeHOST
Just make sure to note which activities make it easier to be present with someone and which make it harder, and recognize that it can be different for different people.
SallyHOST
This is the exact moment private speech goes subterranean, turning into inner speech.
SallyHOST
The ego's silent, continuous self-talk, generated by the default mode network, DMN, our brain's narrative engine and self-talk storyteller.
SallyHOST
Because inner speech internalises the relational tones of your childhood, your ego often talks to you in the exact same way your primary caregivers did.
SallyHOST
What you experience in adulthood as your inner critic is often just a subterranean echo of early relational conditioning.
SallyHOST
The impact of stress and cortisol Physical stress alters this baseline dramatically.
SallyHOST
When you are tired of running high levels of cortisol, the primary stress hormone, your nervous system triggers hypervigilance.
SallyHOST
Your DMN accelerates, making your inner critic louder, faster and more catastrophic.
SallyHOST
People often mistake a stress-induced anxiety loop for a negative intuition or a warning from spirit.
SallyHOST
How early childhood attachment conditioning and emotional states like anxiety, depression or physical exhaustion dictate the baseline volume and shape of those projections.
SallyHOST
and how modern neuroscience, specifically ironic process theory, the default mode network, and predictive processing, provides a neurological engine.
SallyHOST
We will then establish a step-by-step framework to recognise ego projection across three areas.
SallyHOST

SallyHOST
In a depressed or low energy state, the brain's prefrontal inhibitory networks weaken significantly.
SallyHOST
Unresolved shadow material, such as core worthlessness, unexpressed grief or deep-seated isolation, leaks upward continuously into conscious thought, bypassing your normal mental filters and colouring your baseline self-talk with heavy defeatist narratives.
SallyHOST
Step two, the storyteller, the default mode network.
SallyHOST
Once that suppressed thought or fear scenario surges upward through cognitive fatigue, anxiety, depression or low energy, it enters the default mode network, DMN, which is the brain's narrative engine and self-talk storyteller.
Jud BrewerGUEST
And what we found was that there's a network of brain regions.
Jud BrewerGUEST
It's called the default mode network.
Jud BrewerGUEST
And the name is important because it was named before the group knew what the network was doing.
Jud BrewerGUEST
But it's what people default to when they're not doing anything in particular.
Jud BrewerGUEST
Well, it turns out that we default to thinking about ourselves.
Jud BrewerGUEST
So it's a very self-referential network.
Jud BrewerGUEST
So it gets activated, for example, when people are craving, name it, cigarettes, cocaine, chocolate, gambling, all these things activate this default mode network because it's about us.
Jud BrewerGUEST
We just completed a three-year study of a neuroimaging study of people who worry.
SallyHOST
This is the exact moment private speech goes subterranean, turning into inner speech.
SallyHOST
The ego's silent, continuous self-talk, generated by what neuroscientists call the default mode network, DMN, the brain's narrative engine and self-talk storyteller.
SallyHOST
The DMN activates whenever we're not engaged in an active, focused task, constantly constructing our continuous story of me.
SallyHOST
Because inner speech internalises the exact relational tones of your childhood, your ego often talks to you in the exact same way your primary caregivers did.
speaker_1NARRATOR
You train your brain to realize that action, not abstraction, is the true source of reward.
speaker_1NARRATOR
Finally, we must talk about the physical engine of your daydreaming, the default mode network, or the DMN.
speaker_1NARRATOR
This is the network in your brain that lights up when you are doing nothing, wandering through thoughts.
speaker_1NARRATOR
In a maladaptive daydreamer, this network is hyperactive, constantly pulling you away from the present.
speaker_1NARRATOR
Think of mindfulness as weight training for your attention span.
speaker_1NARRATOR
Every single time you catch your mind drifting and gently pull your focus back to the physical sensation of your breath, you perform a mental rep.
speaker_1NARRATOR
You physically shrink the overactive parts of your DMN and strengthen your focus network.
speaker_1NARRATOR
You are taking back the steering wheel of your consciousness.
