'''Bioelectromagnetism''' is the study of electromagnetic phenomena in living organisms. It encompasses:

* The '''membrane potentials''' of cells (~ 70 mV across cell membranes, generated by ion pumps).
* The '''action potentials''' that propagate along nerves and muscles.
* The '''endogenous electromagnetic fields''' of body and brain that are externally measurable (EEG, MEG, ECG).
* The '''body-wide bioelectric fields''' that respond to consciousness, sleep, healing, and intention.
* '''Therapeutic applications''' of external EM fields (TMS, tDCS, PEMF therapy).

Bioelectromagnetism is '''thoroughly mainstream''' as a physiological science; its application to consciousness research and to anomalous-cognition phenomena is where the framework adds claims beyond mainstream physiology.

== Established phenomena ==

=== Cellular bioelectricity ===

Every cell maintains an electrochemical gradient across its membrane via the '''Na/K-ATPase pump'''. The resulting membrane potential of ~ −70 mV is the foundation of:

* Action-potential generation in excitable cells (neurons, muscle).
* Calcium signalling in non-excitable cells.
* Wound-healing electric fields ("injury currents" of order 1 μA/cm2).
* Developmental patterning (Levin group: bioelectric gradients regulate morphology).

=== Brain electromagnetic fields ===

The brain produces externally-detectable electromagnetic fields:

* '''EEG''' (electroencephalogram): scalp-detected ~ μV potentials at 0.1–100 Hz; spatial resolution ~ cm.
* '''MEG''' (magnetoencephalogram): scalp-detected ~ 10–100 fT magnetic fields; better spatial resolution, requires SQUID magnetometer.
* '''ECoG''' (electrocorticogram): intracranial mV-scale fields with sub-mm spatial resolution.
* '''Single-neuron recording''' — extracellular and intracellular signals at the single-cell level.

These signals reflect synchronous activity of large populations of pyramidal cells in cortex.

=== Heart electromagnetic fields ===

The heart produces the body's strongest electromagnetic field — ~ 100× stronger than the brain's. Measurable as ECG (electrocardiogram) and MCG (magnetocardiogram). Body-surface ECG voltages reach mV scale.

=== Body-wide DC fields ===

Robert Becker's work (1960s–1980s) characterised '''body-wide DC bioelectric fields''' that:

* Respond to sleep / wake transitions.
* Modulate during anaesthesia.
* Shift during meditation and altered states.
* Show patterns of polarity around limb regenerating in salamanders.

Becker proposed (and partly demonstrated) that the body-wide DC field is functionally significant, not just an epiphenomenon. The functional-significance claim is partly accepted (developmental bioelectricity is now mainstream via Michael Levin's group) and partly contested.

== Therapeutic bioelectromagnetism ==

External EM fields are used therapeutically:

* '''TMS''' (transcranial magnetic stimulation) — strong ~ T pulses to depolarise cortical neurons. FDA-approved for depression.
* '''tDCS''' (transcranial direct-current stimulation) — weak ~ mA currents through scalp electrodes; modulates cortical excitability. Research and emerging therapeutic uses.
* '''PEMF therapy''' (pulsed-EM-field therapy) — low-intensity pulsed fields used for bone-healing, soft-tissue injuries. FDA-approved for non-union fractures.
* '''Vagus-nerve stimulation''' — implanted electrodes; FDA-approved for epilepsy, depression.

These are routine clinical bioelectromagnetism. They establish that '''external EM perturbations have measurable physiological and cognitive effects''' — relevant context for any field-mediated consciousness theory.

== Magnetoencephalography (MEG) ==

MEG deserves special mention as a recent measurement breakthrough. From the 1970s, SQUID-based MEG systems have improved from single-channel research demonstrations to whole-head 300+-channel arrays. Recent development:

* '''Optically-pumped magnetometer (OPM) MEG''' — Boto et al. ''Nature'' 2018 — wearable MEG systems with comparable sensitivity to SQUID systems, but at room temperature and without the cryogenic SQUID array. Enables naturalistic-behaviour MEG recording.

OPM-MEG is the most likely platform for direct experimental tests of the framework's predictions about ψ-coupled coherent neural activity.

== Body-wide bioelectric coordination ==

The Levin group's 2010s–2020s work has established that '''bioelectric gradients''' regulate developmental and regenerative patterning in unexpected ways:

* Tadpoles given a "third eye" via local bioelectric manipulation grow functional optic structures in non-standard locations.
* Planaria regenerative polarity is determined by bioelectric gradients, not just chemical gradients.
* Frog embryo organ-pattern is encoded in bioelectric maps that precede chemical patterning.

This is mainstream developmental biology and establishes that '''body-wide bioelectric information is functional''' — independently of any consciousness-related claim.

== Framework interpretation ==

In the [[Psionics|psionic framework]]:

* '''Endogenous EM fields''' (brain, heart, body-wide) are direct ψ-sources via the αψ Fμν Fμν vertex. Coherent collective firing produces collective ψ excitation.
* '''External EM perturbations''' (TMS, tDCS, PEMF) couple to ψ via the same vertex — providing experimental knobs to probe ψ-coupling.
* '''Body-wide bioelectric coordination''' provides a non-neural ψ-coupling channel that may be relevant to healing, intention, and non-cognitive psi phenomena.

The framework treats bioelectromagnetism as the '''measurable physical anchor''' for biological ψ-coupling. Detection of framework-specific signatures (small anomalous correlations beyond standard bioelectromagnetism) is the experimental task.

== Sanity checks ==

* '''Dead organism''' → all bioelectric activity decays; ψ-coupling vanishes. ✓
* '''Anaesthesia''' → reduced brain bioelectric coherence; reduced consciousness; reduced ψ-coupling. ✓
* '''External Faraday shielding''' → reduces some external EM signatures but does NOT eliminate body-internal bioelectric activity. ✓ (Important for anomalous-cognition experimental design.)
* '''ψ → 0''' (in framework) → all standard bioelectromagnetism intact; no framework-specific signatures. ✓ ([[Sanity_Check_Limits]] §12.)
