Why Your Brain Accepts Your Own Smell: A Psychextric Theory of Self-Authentication
BY: OMOLAJA MAKINEE
We are taught, socially and instinctively, that certain smells are unpleasant—few more so than the smell of flatulence. And yet, a strange contradiction persists: what repels us from others often fails to provoke the same intensity when it comes from ourselves.
This is usually dismissed as habit, tolerance, or even humour. But within the psychextrical framework, it reveals something far more fundamental:
Your brain is not simply reacting to smell—it is verifying identity.
The reaction to one’s own hydrogen sulfide is not trivial. It is one of the clearest biological expressions of what psychextrics defines as self-authentication.
1. Beyond Habituation: The Difference Between Tolerating and Recognising
In conventional thinking, repeated exposure to a stimulus reduces sensitivity—a process known as habituation. Over time, the brain “ignores” what is constant.
But this explanation fails here.
The difference between reacting to another person’s fart and one’s own is not just repetition—it is origin.
- A foreign stimulus triggers aversion.
- A self-generated stimulus shifts toward affinity.
This is not passive fading. It is active recognition.
2. The GIM–HIM Self-Recognition Loop
In psychextrics, the brain operates through a continuous dialogue between:
- GIM (Genetic Index Marker).
- HIM (Hormonal Index Marker).
- EIM (Epigenetic Index Marker).
- HFI (Hormonal Fluidity Index).
Together, these form a closed-loop system that defines what the organism recognises as self.
When hydrogen sulfide is produced internally, it carries a unique biochemical signature tied to this loop. The moment it is detected:
- The piriform cortex captures the signal.
- The entorhinal interface maps its identity.
- The amygdala evaluates its origin.
And crucially:
The system recognises the signal as self-derived.
3. The Amygdala’s Role: From Threat Detection to Self-Verification
The amygdala is often described as a fear or threat detector. But in psychextrics, its role is broader:
It is the generator of emotional valence based on identity and relevance.
When encountering a foreign smell:
- The signal is treated as a potential intrusion.
- Negative valence (aversion) is applied.
When encountering one’s own smell:
- The signal is identified as an internal echo.
- The amygdala assigns affinity.
Why?
Because the signal confirms:
- The body is metabolically active.
- Internal systems are functioning.
- The organism remains coherent.
This is not just tolerance. It is a biological “all-clear” signal.
4. The Closed-Loop Body: Recycling Meaning Through Chemistry
The body, in psychextrics, is not an open system reacting to random stimuli. It is a closed-loop system continuously validating itself.
The reintroduction of self-generated hydrogen sulfide through olfaction is part of that loop. It allows the brain to:
- Reconfirm internal metabolic status.
- Maintain alignment between detection and identity.
- Stabilise emotional resonance around self-generated outputs.
In simple terms:
The brain recognises its own chemistry—and responds accordingly.
5. From Aversion to Affinity: Why Context Matters
This explains the behavioural paradox:
- Another person’s fart is interpreted as external disruption of aversion.
- One’s own fart is interpreted as internal continuity of acceptance.
The difference is not the chemical. The difference is the relationship to the self. Emotion is not attached to the stimulus—it is assigned through resonance alignment of emotional Template encoding at Detection Spectrum.
6. The Neuroprotective Dimension: Hydrogen Sulfide and Brain Stability
Psychextrics extends this concept further into neurobiology. Hydrogen sulfide is not merely a waste gas—it plays a role in maintaining neural function.
A. Glycogen Synthase Beta Stability
In a balanced system:
- Hydrogen sulfide supports the fluidity of Glycogen Synthase Beta.
- This enables smooth signalling between neurons.
Without this support:
- Molecular processes become rigid.
- Signal transmission degrades.
B. Prevention of Tau Protein Clumping
In conditions such as Alzheimer’s disease:
- Reduced hydrogen sulfide disrupts this balance.
- Glycogen Synthase Beta binds excessively to Tau proteins.
- This creates clumps that block neural communication.
From a psychextric perspective:
These clumps are physical obstructions in the brain’s signal pathways.
They interfere with:
- The thalamic relay circle.
- The display architecture of consciousness.
As communication fails:
- Awareness flickers.
- Memory degrades.
- Cognitive systems collapse.
7. Reinterpreting the “Unpleasant”
What society labels as unpleasant smell may, biologically, serve a function. The reintroduction of one’s own hydrogen sulfide:
- Reinforces internal signalling loops.
- Maintains molecular balance.
- Supports neural integrity.
And the amygdala’s positive or neutral response ensures:
The organism does not reject its own regulatory signals.
8. Adaptation versus Habituation: A Critical Distinction
This phenomenon is not habituation. The brain is not ignoring the smell of its own body. It is adapting to it as self-relevant.
- Habituation produces passive reduction of response.
- Adaptation produces active alignment with internal identity.
In this case:
- The Instinct Spectrum detects metabolic confirmation.
- The Detection Spectrum (piriform) identifies the chemical signature.
- The Orbitofrontal cortex, when engaged, reflects alignment rather than disgust.
The Orbitofrontal Shift: From Disgust to Satisfaction
When valuation reaches conscious display:
- External stimulus of hydrogen sulfide allows the orbitofrontal cortex displays disgust.
- Internal stimulus of hydrogen sulfide allows the orbitofrontal cortex may display neutrality or subtle satisfaction.
Because the signal does not violate internal coherence—it confirms it.
9. The Final Insight: The Self as a Chemical Signature
Psychextrics reframes identity itself. The self is not just:
- A narrative.
- A memory.
- A psychological construct.
It is also:
A biochemical signature continuously verified by the brain.
Smelling one’s own output is not trivial—it is a moment of:
- Internal recognition.
- System validation.
- Biological continuity.
A metabolic “handshake” between body and brain.
Conclusion: What This Reveals About Human Behaviour
This seemingly simple phenomenon exposes a deeper truth:
- Behaviour is not driven by stimuli alone.
- It is driven by how those stimuli relate to the self.
The brain is not asking: “What is this?”
It is asking: “Is this me—or not me?”
And everything that follows—emotion, perception, behaviour—depends on that answer. In this light, even the most ordinary experiences become windows into a fundamental principle:
The organism is always verifying itself—chemically, continuously, and unconsciously.
