GRAVITON / RESEARCH PROPOSAL 01

Circadian Gating
of Temporal Integration.

How the body’s slow rhythms might shape the mind’s experience of time.

By GravitonRevised Hypothesis · Not peer reviewed

FOR THE CURIOUS READER / THE IDEA IN A MINUTE

Could the body’s clocks change how we experience time?

The body’s clocks may shape how we experience time—not by making moments, but by changing how reliably we measure them.

Your body runs on daily rhythms, while your brain processes events on much shorter timescales. This proposal asks whether those slow rhythms change the conditions in which the brain judges time—much as changing the lighting in a room changes what you can see, without setting the speed of your eyes.

The specific prediction is that when local biological clocks become less synchronized, judgments of duration may become less consistent. Feeling that an event lasted longer is a different question from being able to distinguish events more precisely.

What we know: circadian rhythms can affect neuronal excitability. What we do not yet know: whether the complete proposed pathway explains timing judgments, or whether spin-dependent quantum chemistry contributes to it. The interactive figure explores an assumption; it is not an experimental result.

01 / The central hypothesis

Slow biological rhythms may regulate the conditions under which much faster neural processes construct temporal experience. This proposal calls that hierarchy Circadian Gating of Temporal Integration.

Circadian phase and sleep pressure alter cellular conditions that influence neural integration, temporal precision, and duration judgments. Spin-dependent quantum chemistry could contribute to this regulation, but that contribution must be demonstrated independently.

The proposal concerns modulation of temporal experience. It does not assume that quantum collapse generates consciousness, and the current evidence does not establish a probable quantum-consciousness connection.

02 / From biological phase to temporal experience

A plausible starting point is redox regulation and neuronal excitability. Circadian redox changes have been linked to electrical properties in rodent suprachiasmatic nucleus neurons. Human research separately reports circadian variation in cortical excitability. These findings motivate the proposed hierarchy; they do not establish its complete pathway to subjective duration. Wang et al.; Ly et al.

Attention and memory also influence both outputs. Every arrow in the full pathway is a hypothesis to investigate; the dashed branch requires separate evidence.

This architecture avoids requiring a quantum state to remain coherent across the entire sequence. A fast molecular event could leave a longer-lived chemical change that subsequently alters neuronal behavior. A candidate sequence is a spin-dependent reaction changing product yield, followed by altered channel activity and neural integration. Each connection needs measurement. Cryptochrome is a candidate contributor, not an assumed universal bridge.

03 / There is no single “frame rate”

The model separates four measurements. A change in one need not produce the same change in the others.

Temporal resolution
Can two closely spaced events be distinguished?
Prospective duration
How long does an interval seem while attention is deliberately directed toward it?
Retrospective duration
How long does an event seem when remembered?
Timing reliability
How consistent are judgments across repeated trials?

Alpha-oscillation frequency has been associated with visual temporal resolution. That does not establish a universal frequency of consciousness. An intense event can feel longer in retrospect without the brain resolving more perceptual “frames.” Samaha & Postle; Stetson et al.

04 / A distinctive, falsifiable prediction

The proposed extension concerns alignment among local cellular clocks: less alignment could produce less coordinated physiological conditions, more variable neural integration, and less consistent timing judgments.

Disrupting local circadian alignment should increase timing variability even when average sleepiness, mean circadian phase, and task conditions are comparable.

This is an untested prediction, not a finding established by the cited studies. Measuring local clock alignment would initially require appropriate cellular or animal preparations.

EQUATION 01 / CANDIDATE STATISTICAL MODEL
logCVtiming=α+βccosφ+βssinφ+γS+ηA+κ(1−Rφ)+ε

CVtiming is variability relative to mean timed duration; φ is circadian phase; S is sleep pressure; A represents attention; Rφ measures local clock alignment. The coefficients are to be estimated, not assumed known.

The distinctive prediction: κ > 0.

INTERACTIVE 01 / EXPLORE THE ASSUMPTION

When clocks lose alignment.

Spread the phases of 24 illustrative clocks. Then change κ to compare the proposed effect with a null or opposite relationship.

Alignment Rφ—Timing CV / aligned baseline—

Illustration only. No experimental data or fitted parameters. Other covariates are held constant; ε is set to zero. Choosing κ > 0 builds the proposed effect into this display—it cannot confirm the hypothesis.

EQUATION 02 / ALIGNMENT AND ISOLATED MODEL EFFECT
Rφ=|1N∑j=1Neiφj|CV(Rφ)CV(1)=eκ(1−Rφ)

The first expression is a circular phase-alignment measure used for this illustration. The second follows from the candidate model with all other terms held equal. It is a consequence of the assumed equation, not independent evidence.

05 / What the proposal must not assume

Original claimProblem and correction
Clock genes measure “gravitational time.”Circadian clocks are endogenous oscillators entrained by environmental cycles. They do not establish a special link to gravity. Human intrinsic periods average slightly longer than 24 hours. Czeisler et al.
CRY bridges circadian regulation and quantum consciousness.Purified bird CRY4 findings cannot simply be transferred to human CRY1/CRY2. Specify the protein, cell, reaction, and physiological output. Xu et al.; Kutta et al.
Clock genes are a “quantum heat sink.”Metabolic regulation does not demonstrate protection of a quantum state. Measure whether specified cellular conditions alter the relevant coherence lifetime.
Fright reveals a faster conscious frame rate.Expanded remembered duration can occur without improved temporal resolution. Measure these separately. Stetson et al.
Dreams compress hours into minutes.This is not an established general finding. Timed lucid-dream tasks can take comparable or longer periods than waking tasks. Narrative duration is not continuously measured experience. Erlacher et al.
Nighttime repression switches consciousness off.Circadian phase, sleep stage, and conscious experience are distinct variables. Dreaming also occurs in non-REM sleep. Siclari et al.
Sleep prevents “decoherence damage.”Decoherence is not itself a defined cellular injury. This explanation requires a specific damaging process; it is not part of the revised mechanism.

06 / The quantum branch has to earn its place

Circadian biochemical conditions modulate a specified spin-dependent reaction, whose products influence neuronal processing.

This narrower claim requires five independent gates:

  1. A relevant radical pair in native mammalian neural cells.
  2. A characterized formation mechanism, lifetime, and physiological abundance.
  3. A quantitatively predicted spin-dependent change in reaction yield.
  4. Amplification into a measured change in neuronal physiology.
  5. A selective perturbation that changes the proposed effect while preserving ordinary clock function.

A CRY knockout alters many processes. A behavioral change after knockout would not identify quantum causation. A separation-of-function manipulation must be developed and validated.

Human CRY2 expressed in flies was reported to support light-dependent magnetic responses; this was not a human-brain experiment. Later large fly experiments found no magnetic behavioral effects in their tested paradigms, challenging earlier reports. These results justify careful, model-specific investigation rather than a general inference about consciousness. Foley et al.; Bassetto et al.

07 / Keep objective reduction a separate question

Collective microtubule optical behavior and a 2026 mouse study reporting delayed anesthetic loss of the righting reflex warrant investigation. Neither establishes this circadian mechanism or distinguishes quantum consciousness from ordinary cellular effects. Loss of the righting reflex is a behavioral endpoint, not a direct measurement of subjective experience. Babcock et al.; Huang et al.

EQUATION 03 / THE ORCH OR PROPOSAL
τOR∼ℏEG

EG is the gravitational self-energy associated with different superposed mass distributions. It is not the cell’s available metabolic energy.

Linking melatonin or ATP to collapse frequency would require a physical mechanism connecting them to the quantum state and its mass distribution. A familiar illustrative interval in Orch OR is about 25 milliseconds; this is not an established kHz–MHz conscious sampling rate. Objective reduction remains a separate hypothesis needing discriminating evidence. Hameroff & Penrose

08 / Four experiments that could change the assessment

ExperimentSupporting resultResult that challenges it
Separate circadian phase from time awake using controlled schedules and endogenous phase markers.Timing performance follows biological phase beyond sleep-pressure effects.Precise results exclude the predicted phase effect.
Manipulate clock phase, measure redox and neural integration, then independently restore the proposed mediator.The physiological effect follows the manipulation and reverses with rescue.The mediator changes without the predicted downstream effect.
Manipulate local clock alignment while tracking other neural conditions.Timing variability increases and recovers after resynchronization.Verified misalignment leaves timing precision unchanged within meaningful bounds.
Perturb an independently characterized spin reaction.Molecular and neural changes match advance quantitative predictions.Ordinary biochemical or physical effects explain observations equally well.

Positive results in the first three experiments would strengthen the physiological theory. A positive fourth result could establish a functional quantum contribution. Demonstrating objective reduction would still require its own discriminating evidence.

Effect sizes, exclusion bounds, controls, and analysis plans should be specified before data collection. A credible hypothesis is strengthened by stating what would count against it.
