Sensory Saturation and Cognitive Surrender: A Theoretical Framework for Altered Perceptual States in Immersive Neurogastronomic Dining
PsyArXiv Preprints July 16, 2026 DOI: osf:8sepv_v1 via PsyArXiv
Summary
A theoretical framework interprets immersive neurogastronomic experiences as a form of ambient cognitive modulation. Based on informal observation of approximately 6,000 guests over six years at Sensorium, an eleven-seat restaurant with controlled multisensory architecture, the authors propose that intentional, layered sensory overstimulation may selectively inhibit dominant analytical processing and reduce Default Mode Network activity, favoring a shift in brain oscillatory states from alpha toward theta. This hypothesized neurobiological shift, potentially observable within a single dining session, may correspond to heightened presence, reduced critical self-monitoring, and access to ordinarily unavailable inner states. A three-stage model—Saturation, Analytical Surrender, and Incorporeal Immersion—is introduced.

Abstract
This paper proposes a theoretical framework for interpreting immersive neurogastronomic experiences as a form of ambient cognitive modulation. The framework originates in the direct, informal observation of approximately 6,000 guests conducted by the first author over more than six years of operation at Sensorium — an eleven-seat neurogastronomic restaurant with a controlled multisensory architecture. The recurrence of consistent behavioural and experiential patterns across this substantial case base motivated a search for a systematic neurological and psychological interpretation, developed in collaboration with the second author drawing on his clinical expertise and the Emotional Flavour Profiles framework (Kiosses, 2026). We propose that intentional, layered sensory overstimulation may selectively inhibit dominant analytical processing — in the sense described by McGilchrist's account of hemispheric functional dominance — and reduce Default Mode Network (DMN) activity, favouring a shift in brain oscillatory states from alpha toward theta. This hypothesised neurobiological shift, potentially observable within the span of a single dining session, may correspond to a subjective experience of heightened presence, reduced critical self-monitoring, and access to ordinarily unavailable inner states. We introduce a three-stage model — Saturation, Analytical Surrender, and Incorporeal Immersion — and discuss its implications for experiential design, clinical psychology, and wellbeing research.
