Abstract
Background: Subjective experiences featuring altered self-awareness, temporal perception, or spatial boundaries—termed Non-Ordinary Experiences (NOEs)—occur across clinical neurology, psychiatry, and psychedelic medicine, including in insular ecstatic seizures, meditation, breathwork, hypnosis, and psychedelic therapy.
Objective: To synthesize neurobiological and clinical literature on NOEs for neurologists by presenting three heuristic frameworks: 1. A six-dimension phenomenological taxonomy; 2. A tri-level descriptive taxonomy (computational "software", neuromodulatory-autonomic "firmware", and network "hardware"); 3. The Trigger–Dynamic Psyche–4E Appraisal–Outcome Model, which maps how acute neurodynamic shifts resolve into adaptive growth or clinical distress without reducing existential meaning to neural activity.
Methods: Narrative synthesis of systematic reviews, coordinate-based meta-analyses, and key theoretical frameworks sourced via PubMed/MEDLINE.
Results: Conflating spirituality, religion, and NOEs causes construct contamination in neuroimaging, compounded by unvalidated single-item measures and non-independent cohorts. An fMRI meta-analysis of meditation (34 studies, N=700) reveals aggregate recruitment of the right rolandic operculum, left insula, supplementary motor area, and hippocampus, arguing against a singular "spiritual center". First-person reports are mapped using a six-dimension schema (experiential content, temporal dynamics, spatial dynamics, volitional dynamics/agency, ownership/embodiment, cognitive stance). Mechanistically, states are organized across three bidirectionally coupled levels: computational inference ("software"), neuromodulatory-autonomic state-setting ("firmware"), and large-scale networks ("hardware"). Five entry routes (meditation, psychedelics, breathwork, hypnosis, focal neurological events) are hypothesized to share shifts in Bayesian precision weighting and network decoupling within the master Trigger–Dynamic Psyche–4E Appraisal–Outcome Model. Crucially, long-term outcomes (integration vs. distress) are not dictated by acute brain states alone, but are mediated by contextual filtering through the 4E Appraisal Prism (embodied, embedded, enacted, extended dimensions).
Conclusions: Neurospirituality bridges network neuroscience, clinical neurology, and person-centered care. Clarifying biological substrates does not resolve existential validity. Clinicians must maintain a strict distinction between biological mechanisms, subjective experiences, and personal meanings (the Epistemological Invariant) to avoid pathologizing adaptive states or romanticizing neurological disease.
