The Default Mode Network (DMN), The Task Positive Network (TPN) and Neurodiversity

Discover how the brain’s Default Mode Network (DMN) and Task Positive Network (TPN) shape creativity, focus, and task transitions, especially in neurodivergent individuals. Explore their role in ADHD and autism, practical tips for balance, and why celebrating neurodiversity unlocks incredible potential.

What is the Default Mode Network (DMN)?

The Default Mode Network (DMN) is the cognitive functional system that is our internal world. It is behind intrinsic thoughts, processing and analysing of external stimuli, daydreaming, planning and goal setting. (The default mode network: where the idiosyncratic self meets the shared social world)

The DMN is how we make sense of the world, and how we can create novel, unique and expansive ideas and creations.

The DNM includes the posterior medial cortex, medial prefontal cortex, and temporoparetial junction. It is responsible for the non-stimulus-induced tasks, in other words, mind processing that aren´t externally prompted, such as mind wandering, philosophizing, catastrophizing, ideation, and other thinking processes.

The DNM is dormant when the individual is engaged in external stimuli tasks, or mentally occupied of their current surroundings, or what is often referred to as “the present moment”, which is when the TPN takes over.

What is the Task Positive Network (TPN)?

The Task Positive Network (TPN) becomes active when we are faced with attention-demanding tasks. (TPN vs. DMN – Neural Mechanisms and Mindfulness)

The TPN is involved with short term memory, abstract thinking, sensory input, task orientation and action-orientated activities.

The TPN includes the Lateral prefrontal cortex, the Anterior cingulate cortex, the Insula, and the Somatosensory Cortex.

How DMN and TPN are two opposing networks

The DMN and TPN work contrary to each other, and in most people, the two networks balance each other for the individual to make sense of their world. When task focused, they simply focus on the task on hand, having the TPN active and when in a still, relaxed state without stimuli, they may daydream, ruminate, go over events of their day, the past or future plans.

Most individuals are dominant in one of either networks: if TPN dominant, they tend to be task-focused, extrinsically motivated and respond well to external events, emotionally stable, may seem uncaring and less prone to overthinking and ruminating. A DMN dominant person may be seen as a people-person, empath, and daydreamer. They are expansive in their thoughts, and prone to overthinking of events, ruminate and dwell over the past or worry about the future. (Good at tasks, bad at people)

How DMN and TPN play a role in Neurodiverse individuals

Many studies show a link between DMN, TPN and how Neurodiverse individuals relate to their world. Compared to a neurotypical individual that mainly operate in one network at a time, a person with ADHD, Autism, Bipolar Disorder, schizophrenia, BPD, NPD and other Neuropsychological disorders, may switch rapidly between these network, have decreased function in parts of either network, or delayed processing between TPN and DMN.

Neurodiversity and the DMN/TPN Balance

For neurodivergent people, the balance between the DMN and TPN might look different. For instance, individuals with autism may find comfort in deep focus but struggle with transitions out of task-oriented modes. Those with ADHD might have a hyperactive DMN, leading to difficulty focusing or staying on-task. However, these differences are not deficits—they reflect the unique wiring of neurodiverse brains, which often excel in creativity, innovation, and problem-solving when supported appropriately.

Cultivating Harmony Between the Networks

Tools like mindfulness, breathwork, and personalized coaching can help individuals manage these networks effectively. Techniques such as focusing on the breath or engaging in structured, stimulating tasks can help shift activation from the DMN to the TPN. Conversely, allowing time for reflection or engaging in creative outlets can nurture a healthy DMN.

Embracing Neurodiversity

Understanding the interplay of the DMN and TPN deepens our appreciation for neurodiversity. It underscores the importance of tailoring strategies to individual needs rather than imposing a one-size-fits-all approach. By celebrating the strengths of neurodivergent individuals, we create a world that values diverse contributions and fosters innovation.

At Timeless Healing, we use neuroscience-informed techniques to help individuals harness their strengths, navigate challenges, and thrive in their unique ways. Whether through coaching, mindfulness, or holistic wellness practices, we’re here to help you embrace your neurodivergent brilliance.

Why Some Clients Feel Worse After Breathwork (and How to Prevent It)

January 2, 2026 No Comments

Breathwork is often described as calming, regulating, or even transformational. And for many people, it is. But for others, breathwork can feel uncomfortable, overwhelming, or even destabilising. When this happens, it’s not because the client or coach is “doing it wrong” — it’s usually because the breathwork wasn’t matched to their nervous system, history, or capacity in that moment.

Understanding why some clients feel worse after breathwork is essential for anyone who wants to integrate breathwork into their professional work safely and ethically.

Why Women with ADHD Often Struggle After Narcissistic Relationships

October 9, 2025 No Comments

Leaving a narcissistic relationship is never easy. For women with ADHD, the challenges can feel even heavier — not because they are weak or incapable, but because ADHD traits often intersect painfully with the dynamics of narcissistic abuse.

As an ADHD coach, I’ve seen many women step out of these relationships and wonder why healing feels so complicated. If this is you, know this: it makes sense, and you are not alone.

Alcohol is ruining my life – but I´m not the drinker!

When people hear the word alcoholic, they tend to picture the person who drinks. What often gets left out of the conversation are the people standing next to them — the ones quietly enduring the chaos, walking on eggshells, holding families together, and breaking down in silence.

Are you someone who suffers from someone else´s alcohol dependency or addiction? There is help..

Breathwork is a powerful tool for reducing stress, improving focus, and regulating emotions— In today’s corporate landscape, wellness is no longer just a “nice-to-have”—it’s a necessity.

While free coffee and casual Fridays might boost morale temporarily, what your people really need is space to pause, reset, and reconnect with themselves and each other.

That’s where breathwork comes in.
