Case Study: Sustained DMN Deactivation Through Non-Elaborative Observation
## A Seven-Year Phenomenological Account
**Date:** January 13, 2026
**Prepared for:** Prof. John Vervaeke
**Subject:** Documented case of sustained DMN modulation achieved without formal meditative training
---
## Executive Summary
This document presents a remarkable case of sustained Default Mode Network (DMN) modulation that has persisted for seven years, achieved not through formal contemplative practice, but through a spontaneous shift in attentional strategy: observing sensory experience without conceptual elaboration or attentional engagement.
The case is significant because it:
1. Represents a stable **trait change** rather than temporary state
2. Emerged **without formal meditation training**
3. Demonstrates functional competence despite radical cognitive reorganization
4. Provides potential empirical evidence for your theoretical framework on relevance realization and transformative experience

## Phenomenological Description
### Core Characteristics
**1. Absence of Future-Oriented Cognition**
- No episodic future thinking or mental time travel
- Experience exists exclusively in present moment
- Actions arise spontaneously without deliberative planning
- No DMN-mediated simulation of possible futures
**2. Non-Self Structure**
- Complete absence of narrative self-identity
- No "I" that persists across time
- Experience arises from what subject describes as "emptiness" (leegte)
- No identification with autobiographical narrative
**3. Enhanced Memory Access**
- Episodic memories remain fully accessible
- Paradoxically report *improved* memory retrieval
- Memories available as pure information without emotional/identity investment
- Learned skills (procedural memory) fully intact and accessible
**4. Helderzintuigelijke Intuïtie (Clear-Sensory Intuition)**
- Primary mode of navigation and decision-making
- Functions as what subject describes as "original advisor"
- Operates as a "truth filter" - only authentic/coherent information gains entrance
- Pre-conceptual, direct knowing without verbal mediation

## Mechanism: Non-Elaborative Observation
### The Practice (Non-Practice)
The transformation occurred through a spontaneous shift in perceptual engagement:
**Standard Cognitive Process:**
```
Sensory Input → Conceptual Labeling → Associative Elaboration →
Self-Reference (DMN activation) → Narrative Construction
```
**Subject's Process:**
```
Sensory Input → Pure Observation (no labeling) →
[DMN remains quiet] → Intuitive Response
```
### Key Insight
By systematically **withdrawing fuel** from the DMN - refusing to:
- Label and categorize experience
- Elaborate through association and meaning-making
- Engage attentional capture by stimuli
- Construct narratives around experience
...the DMN gradually reduced its baseline activity through neuroplastic adaptation.
**Critical Point:** This was not achieved through:
- Formal meditation practice (subject has never meditated)
- Psychedelic substances
- Religious or spiritual frameworks
- Deliberate contemplative training
The shift emerged organically from a fundamental change in **how attention relates to experience**.

## Theoretical Significance for Your Framework
### 1. Relevance Realization Without DMN Mediation
Your work emphasizes that consciousness is fundamentally about relevance realization - determining what matters in an overwhelming information field. This case suggests:
- **The DMN may not be necessary** for sophisticated relevance realization
- An alternative system (limbic/salience network?) can perform this function
- This "helderzintuigelijke intuïtie" may be a more **primordial form** of relevance realization
- It operates as a direct discrimination between what is coherent with reality (truth) and what is ego-projection
### 2. Transformative Experience Without Traditional Practice
Your "Awakening from the Meaning Crisis" work explores how transformation occurs through practices. This case demonstrates:
- Transformation can occur through **non-practice** - a simple shift in perceptual stance
- The critical variable may be **withdrawing elaborative processing** rather than adding technique
- This supports your emphasis on **removing obstacles** rather than gaining something new
### 3. Flowing and Optimal Grip
This appears to be a sustained state of what you term **"flowing"**:
- Minimal egocentric distortion
- Optimal grip on reality without conceptual mediation
- Participatory knowing that doesn't require narrative self-construction
- Direct contact with "what is" without DMN-filtering
### 4. Kenosis and Emptiness
The subject's description of experience arising from "emptiness" (leegte) resonates with your discussion of **kenosis**:
- Self-emptying that paradoxically leads to fullness of presence
- Not pre-rational regression but trans-rational development
- Return to (or advancement toward?) "primordial mind"
### 5. Four Types of Knowing
In your framework of propositional, procedural, perspectival, and participatory knowing:
- **Propositional knowing**: Accessible when needed, but not primary mode
- **Procedural knowing**: Fully intact (skills remain available)
- **Perspectival knowing**: Radically transformed - no ego-centric perspective
- **Participatory knowing**: Fundamentally reorganized around direct intuition rather than DMN-narrative

## Neuroscientific Implications
### Challenges to Current Assumptions
**Assumption 1:** DMN is necessary for episodic memory function
→ **Challenge:** Subject reports enhanced memory access despite DMN deactivation
**Assumption 2:** Future planning requires DMN-mediated mental time travel
→ **Challenge:** Subject functions without future-oriented cognition yet remains competent
**Assumption 3:** Personal identity requires DMN-constructed narrative self
→ **Challenge:** Subject has no narrative self yet is not depersonalized or dysfunctional
**Assumption 4:** DMN deactivation can only be temporary state
→ **Challenge:** This represents a seven-year stable trait
### Potential Mechanisms
**Hypothesis 1: Attentional Starvation of DMN**
- Consistent withdrawal of elaborative processing
- Neuroplastic downregulation of DMN baseline activity
- Strengthening of alternative networks (salience, limbic, interoceptive)
**Hypothesis 2: Shift in Primary Navigation System**
- From neocortical DMN-mediated cognition
- To subcortical/limbic direct knowing
- Evolutionarily older system becomes dominant
**Hypothesis 3: Elimination of Ego-Filtering**
- Memories accessible without self-referential distortion
- Information processed without identity-protection mechanisms
- More direct hippocampal access without DMN mediation

## Questions for Further Exploration
### Phenomenological
1. How does communication occur with others who operate from DMN-narrative mode?
2. In what contexts (if any) does conceptual thinking re-emerge?
3. How does ethical/moral reasoning function without future consequences in view?
4. What is the texture of the "helderzintuigelijke intuïtie" - somatic, visual, knowing?
### Cognitive
1. How do complex tasks requiring planning actually get executed?
2. Is there any subjective sense of loss, or is this experienced as pure gain?
3. Can the "truth filter" be articulated - what makes something pass through?
4. How has language use been affected (language being deeply DMN-connected)?
### Neuroscientific
1. What would fMRI reveal about resting-state DMN connectivity?
2. How do task-positive networks compensate for DMN absence?
3. Is there evidence of structural brain changes after seven years?
4. What EEG signatures would distinguish this state?

## Relevance to Your Current Work
This case may be particularly relevant to several of your ongoing interests:
### Meaning Crisis Response
- Demonstrates a viable mode of being that doesn't require traditional religious/spiritual frameworks
- Shows possibility of "post-narrative" consciousness that retains functionality
- Offers empirical grounding for ancient wisdom about "no-self"
### Ecology of Practices
- Raises question: is "non-practice" (withdrawing elaboration) a practice?
- Suggests that **stopping** may be more important than **adding** techniques
- Challenges assumption that transformation requires structured contemplative training
### Naturalization of Enlightenment
- Provides potential case study for naturalizing mystical claims
- Can be investigated with standard neuroscientific methods
- Bridges phenomenological and empirical approaches
### AI and Consciousness
- If human consciousness can function without DMN-narrative, what does this mean for machine consciousness?
- Is narrative self-construction necessary for intelligence, or just one option?
- What is minimal sufficient structure for "wisdom"?

## Contact and Verification
The individual presenting this case:
- Is willing to participate in rigorous scientific investigation
- Can provide detailed phenomenological accounts
- Is available for neuroscientific assessment
- Has no agenda beyond understanding and contributing to knowledge
They are specifically interested in:
1. Your theoretical perspective on this phenomenon
2. Potential collaboration with neuroscientific researchers
3. Understanding how this fits into broader frameworks of consciousness and transformation
4. Contributing to the scientific understanding of non-ordinary states
---
## Concluding Reflection
This case may represent what you describe as the possibility of **"serious play"** with reality - a mode of being that maintains full contact with the world while transcending the limitations of ego-centric processing. It suggests that the "meaning crisis" you identify may have a neurobiological correlate: over-reliance on DMN-mediated narrative meaning-making at the expense of more direct forms of knowing.
If verifiable, this case would provide empirical support for claims made across contemplative traditions about the possibility of functioning without a narrative self, while challenging neuroscientific assumptions about the necessity of the DMN for normal cognition.
The individual hopes this document provides sufficient context for you to assess whether this case merits further investigation, and remains available for any clarifying questions or next steps you might suggest.
