Foundational photic driving work: periodic visual flicker entrains EEG oscillations at the stimulus frequency.

SSVEP amplitude peaks near 10 Hz (alpha) with a secondary peak near 6 Hz (theta); basis for the entrainment mode frequencies.

Review of temporal flicker to cortical response; confirms 10 Hz as the peak SSVEP driver.

Troxler, I.P.V. (1804). Über das Verschwinden gegebener Gegenstände innerhalb unseres Gesichtskreises. Ophthalmologische Bibliothek.

The fixation dot exploits Troxler fading: sustained peripheral stimulation disappears from awareness while the attended centre stays stable.

Voss, R.F. & Clarke, J. (1975). '1/f noise' in music and speech. Nature, 258, 317–318.DOI ↗

Auto-drift multiplies incommensurate sinusoids to approximate the 1/f spectral structure of natural fluctuation.

Mather, G., Verstraten, F. & Anstis, S. (Eds.) (1998). The Motion After-Effect: A Modern Perspective. MIT Press.

Direction-selective adaptation underlies the waterfall illusion. Brief direction reversals reset the adaptation plateau, sustaining the after-effect over long sessions.

Peripheral optic flow dominates vection (self-motion perception); the radial vignette removes edge distractors and strengthens the tunnel illusion.

De Valois, R.L. & De Valois, K.K. (1988). Spatial Vision. Oxford University Press.

Peak human contrast sensitivity at 3–4 cycles per degree; basis for the aspect-ratio-driven density auto-detection.

High spatial-frequency square-wave gratings trigger pattern glare and migraine; supports a comfortable density range and smooth gradients over hard edges.

Achromatic high-contrast patterns preferentially drive the magnocellular (motion/peripheral) pathway; chromatic patterns add parvocellular engagement with different temporal tuning.

Kirsch, I. & Lynn, S.J. (1995). The altered state of hypnosis: changes in the theoretical landscape. American Psychologist, 50(10), 846–858.DOI ↗

Response expectancy: the expectation of hypnotic effects is itself the primary mechanism producing them. Basis for pre-induction framing.

Hypnosis weakens prefrontal executive control, letting suggestions activate subsystems more directly. Why permissive suggestions ("you might find…") work: the critical faculty is quieted, not overcome.

PET evidence that hypnotic suggestion modulates anterior cingulate activity directly, the conflict-monitoring region.

Repeated pairing of a focal attention object with rhythmic verbal cues produces a conditioned parasympathetic response. Basis for fractionation deepening.
