Information Transfer at Biological Death: A Quantum-Thermodynamic Framework

This paper addresses a neglected physical question at the boundary of biological death: if consciousness is physically instantiated as information processing, and if physical information is not annihilated under quantum theory, what happens to consciousness-related information when the brain shuts down? The paper develops a quantum-thermodynamic framework in which biological death is modeled not as immediate informational disappearance, but as a transient boundary event. The central proposal is that cellular death releases stored chemical, ionic, and membrane energy, temporarily increasing the conditions for coherence and opening a short transfer window. This window is interpreted as a possible physical basis for near-death experience occurrence and vividness. The framework is motivated by three empirical anchors. First, prospective NDE studies report that roughly 10–20% of cardiac-arrest survivors describe NDEs, with van Lommel et al. reporting an 18% incidence rate in a 344-patient cohort. Second, dying-brain EEG studies report paradoxical gamma surges near death, including Xu et al.’s human data and earlier Borjigin rat data, challenging the idea that the brain simply fades into noise. Third, NDE reports show recurring structural features across cultures, suggesting either a shared neurobiological process or a deeper common transfer architecture. The paper introduces four model equations describing death-related energy release, transfer-window duration, information throughput, and NDE vividness. A two-variable model combining brain readiness and environmental transfer conditions is calibrated to reproduce the reported 18% NDE incidence and the observed NDE depth distribution across seven calibration targets. This is presented as calibrated model consistency, not as independent proof of post-mortem survival. The model produces seven testable predictions. The two most important discriminating predictions are that hypothermia should increase NDE frequency by slowing decoherence, while anesthesia should decrease NDE frequency by suppressing coherence. A further exploratory prediction proposes that NDE light descriptions may cluster around warm solar-like color temperatures. The paper also proposes future reanalysis of dying-brain EEG recordings, cold-water drowning survivor data, anesthesia-depth data, and prospective cardiac-arrest studies with high-density EEG. The conclusion is deliberately limited. This paper does not prove that consciousness survives death. It argues that information transfer at biological death is not obviously prohibited by known physics, and that the dying-brain gamma surge, NDE incidence patterns, and environmental modifiers can be organized into a falsifiable quantum-thermodynamic model. In the broader Information Physics Series, the paper functions as the middle bridge: Paper 5 proposes how consciousness-information may become physically available, Paper 6 models how it may transfer at death, and Paper 4 proposes a preservation-compatible information framework.
