The Split Guardrail of the Cortical Canvas: Imagination, Actuality, and the Hidden Architecture of Conscious Display
BY: OMOLAJA MAKINEE
Modern Behavioural science inherited a dangerous simplification about conscious display:
That the brain passively observes reality exactly as it exists.
Under this assumption, Imagination andPerception became treated as neighbouring psychological experiences occurring inside a unified conscious mind. The cortex was viewed as:
- the generator of thought,
- the creator of imagination,
- and the observer of the external world
simultaneously.
Psychextrics dismantles this entire framework.
Consciousness is not the builder of reality. It is the rendered projection of integrated behavioural signals assembled beneath awareness.
The human organism therefore does not directly experience objective reality nor pure internal fantasy. Instead, conscious display emerges through a split guardrail within the cortical canvas itself:
A structural divide between externally anchored sensory rendering and internally generated imaginative projection.
This hidden separation explains why some sensory experiences can be vividly imagined, why others cannot; why emotions colour perception, and why the self experiences reality as a seamless cinematic projection despite the brain operating through deeply divided cephalic systems.
1. Conscious Display as Rendered Projection
Under psychextrics, awareness behaves less like a sovereign observer and more like a behavioural cinema projected onto the Telencephalic screen.
The organism does not consciously construct reality from above. Reality emerges through:
- survival weighting,
- emotional indexing,
- contextual valuation,
- memory integration,
- hormonal modulation,
- and cephalic negotiation
occurring beneath symbolic perception.
Only afterward does the Telencephalon render the completed behavioural signal into conscious awareness.
The conscious self therefore becomes:
- reflective,
- reconstructive,
- narrational,
- and display-oriented.
This architectural inversion completely reframes imagination itself.
Imagination is not a mystical creative force floating freely inside consciousness. It is a downstream cortical rendering event driven by internally generated subcortical signals.
The cortex fills sensory templates using behavioural material supplied from below whenever external environmental input becomes incomplete, absent, or behaviourally insufficient.
2. The Piriform Cortex and the Boundary of Imagination
The clearest evidence for this split guardrail emerges through the strange behaviour of the piriform cortex: the brain’s primary olfactory display screen.
Unlike almost every major sensory territory within the cortical mantle, the piriform cortex largely bypasses the standard thalamic relay architecture. Instead, it sits at a specialised intersection between:
- the olfactory bulb,
- and the bidirectional entorhinal relay loop of the Siencephalon.
This unique structural arrangement exposes one of the deepest constraints within human imagination:
Smell possesses remarkably weak imaginative reconstruction.
Human beings can vividly imagine:
- faces,
- voices,
- movement,
- visual scenes,
- emotional situations,
- and symbolic narratives.
Yet people generally struggle profoundly to internally reproduce the raw sensory experience of smell itself.
Why?
Because the piriform cortex is rigidly stimulus-driven. It requires actual airborne chemical molecules binding physically to the nasal epithelium before its cortical templates fully activate.
This subcortical architecture lacks a synthetic reconstruction engine capable of generating a fully vivid chemical sensory field internally without external molecular presence.
3. The Structural Silence of Smell
This creates what psychextrics identifies as the structural silence of olfactory imagination.
An individual may vividly recall:
- a childhood kitchen,
- the emotional comfort of home,
- a grandmother’s cooking,
- or the atmosphere surrounding a favourite meal,
while remaining unable to consciously reproduce the actual smell itself.
The emotional meaning survives. The contextual memory survives. The autobiographical continuity survives. But the piriform cortex remains functionally quiet because no external chemical anchor exists to activate its display grids directly.
The organism therefore “knows” the smell behaviourally while being unable to truly reconstruct the “smell” it consciously.
This distinction exposes something profound:
The cortical mantle is structurally divided between externally anchored actuality and internally projected imagination.
4. The Split Guardrail of the Cortical Canvas
Psychextrics identifies two major functional territories within the cortical canvas.
The first camp consists of External sensory cortices.
These regions remain tightly bound to physical environmental stimuli.
They map:
- light,
- sound,
- pressure,
- chemical tastants,
- and external geometry
directly from the outside world.
These territories include:
- the Primary Visual Cortex,
- Primary Auditory Cortex,
- Somatosensory Cortex,
- Gustatory Cortex,
- and the Piriform Cortex.
These systems require external objects to fully populate their sensory templates.
The second camp consists of Internal imagination cortices.
These territories operate primarily as landing pads for:
- emotional simulations,
- autobiographical continuity,
- imaginative projection,
- behavioural anticipation,
- and internally generated narrative overlays.
These regions include:
- the Orbitofrontal Cortex,
- Medial Prefrontal Cortex,
- Posterior Cingulate Cortex,
- and paralimbic association territories.
Unlike the external sensory cortices, these systems are driven primarily by subcortical behavioural projection.
5. The Orbitofrontal Cortex and the Colouring of Reality
The Orbitofrontal Cortex becomes especially important within this architecture because it acts as one of the principal rendering surfaces for emotional imagination.
While the primary sensory cortices map the cold geometry of the external world, the Orbitofrontal Cortex overlays that geometry with:
- attraction,
- disgust,
- danger,
- desire,
- expectation,
- emotional anticipation,
- and imaginative meaning.
The organism therefore never consciously experiences neutral reality.
Every conscious perception arrives already coloured by the spectral variations of:
- hormonal timing,
- behavioural saliency,
- contextual weighting,
- and subcortical emotional projection.
This is why two individuals standing inside the same room can consciously inhabit completely different realities.
The external geometry may remain identical. But the internal behavioural projection differs.
The cortex therefore displays a fusion between actuality and imagination.
6. Imagination Is Not Fabricated by the Cortex
One of the greatest errors of classical Psychology was treating imagination as evidence of sovereign cortical creativity. Psychextrics reverses this completely.
The cortex does not independently invent imagination. The cortex mirrors internally generated behavioural simulations already assembled beneath awareness by the:
- Diencephalon,
- Siencephalon,
- and lower three cephalic systems.
The internal self projects behavioural meaning upward.
The cortex merely renders that meaning symbolically as:
- fantasy,
- anticipation,
- memory visualisation,
- dread,
- daydreaming,
- and emotional simulation.
The imagination therefore originates below consciousness, before appearing consciously.
7. The Unified Behavioural Cinema
The genius of the human organism lies in how seamlessly these divided systems become integrated.
The external sensory cortices provide the geometry of the world. The internal imagination cortices provide the emotional colouration, the symbolic narrative, the danger, the romance, the anticipation, and the meaning of how the internal architecture of the organism perceives the external world.
The organism experiences these fused streams as one seamless conscious reality. This is why consciousness feels unified despite being generated through deeply fragmented cephalic systems operating beneath awareness.
The self becomes the witness to the collision between:
- external actuality,
and:
- internal imagination.
Conclusion: The End of Objective Conscious Display
Psychextrics therefore destroys the myth that human beings consciously observe a neutral external universe.
The organism never encounters reality in its raw form. Reality always arrives filtered through:
- behavioural saliency,
- emotional valuation,
- hormonal timing,
- memory indexing,
- and imaginative projection.
Conscious display itself becomes a rendered behavioural cinema, projected across the cortical canvas through negotiations occurring continuously beneath symbolic awareness.
The split guardrail between Imagination and Actuality is therefore not a flaw of the brain. It is the very architecture that allows the diversity of a specie to survive, anticipate, simulate, fear, desire, remember, and project meaning into the world around their own cohort.
The cortex does not passively observe reality. It renders a living behavioural film where the external world supplies the stage, while the subcortical self supplies the script, the lighting, the danger, and the emotional atmosphere.
And the conscious “I” sits inside the theatre believing the projection itself is its own making.
