Biofield Physiology: A Framework for an Emerging Discipline.

The short version

This framework paper asked whether the body's own energy fields deserve their own branch of physiology. The authors — including cell biologist Michael Levin, known for bioelectricity research in regeneration — define biofields as spatially distributed fields the body generates that can carry information and influence cells and tissues, complementing the familiar chemistry of hormones and neurotransmitters. Their starting point is disarmingly conventional: hospitals already read the body's fields every day. An ECG measures the heart's electrical field, an EEG the brain's; their magnetic counterparts (MCG and MEG) are standard research tools. The paper builds outward from there to less familiar findings: patterns of electrical voltage across cell membranes that guide how tissues develop and regenerate, direct-current fields that switch on when tissue is damaged, and ultraweak photon emission — extremely faint light the body gives off — whose fluctuations track cerebral blood flow, brain energy use, and EEG activity. The framework's second half addresses how such fields could be sensed: molecular receptors (including DNA regions reported to respond to specific electromagnetic frequencies), sites where electrical charge flows, and the body's own generated fields. As real-world proof that fields can heal, the authors point to pulsed electromagnetic field therapy for stubborn bone fractures, which a Cochrane review found may offer benefit and which the US FDA has approved. The honest limits are stated plainly: many findings are preliminary, the various fields have not been shown to form one coordinated regulatory system, and no mathematical model yet captures their long-range behavior. No condition was treated and no clinical claim is made. The paper's value is as a mechanism map — it gives energy-medicine research a physiological vocabulary grounded in measurable biology rather than metaphor alone.

Key findings

• Biofields are defined as the body's own spatially distributed fields — electrical, magnetic, and biophotonic — proposed to carry regulatory information alongside biochemistry.
• Conventional medicine already measures biofields daily: the ECG reads the heart's electrical field and the EEG the brain's.
• Patterns of electrical voltage across cell membranes help guide development and regeneration, and damage-triggered direct-current fields initiate tissue repair responses.
• The body emits ultraweak photon emission (extremely faint light) whose fluctuations correlate with cerebral blood flow, brain energy metabolism, and EEG activity.
• Pulsed electromagnetic field therapy for slow-healing bone fractures — Cochrane-reviewed and FDA-approved — is cited as proof that applied fields can have clinical effects.
