Understanding the Feedback Loops between Energy, Matter and Life. This article proposes that electric and electromagnetic forces are the most important mediators over large distances. Field-like mediation is distinguished from cell-to-cell communication by special electric- or ion-guiding mechanisms that create additional pathways to the "classical" mediators such as nerve conduction or blood flow. Resonance phenomena from phonons and photons in the visible range will be discussed in relation to organelles, cytoskeletal elements and molecules. In this context, the aqueous surrounding of molecules and cells is an important aspect. PMID: 36575844.
The Slowest Shared Resonance: A Review of Electromagnetic Field Oscillations Between Central and Peripheral Nervous Systems. Electromagnetic field oscillations produced by the brain are increasingly being viewed as causal drivers of consciousness. Recent research has highlighted the importance of the body's various endogenous rhythms in organizing these brain-generated fields through various types of entrainment. We expand this approach by examining evidence of extracerebral shared oscillations between the brain and other parts of the body, in both humans and animals. We then examine the degree to which these data support one of General Resonance Theory's (GRT) principles: the Slowest Shared Resonance (SSR) principle, which states that the combination of micro- to macro-consciousness in coupled field systems is a function of the slowest common denominator frequency or resonance. This principle may be utilized to develop a spatiotemporal hierarchy of brain-body shared resonance systems. It is predicted that a system's SSR decreases with distance between the brain and various resonating structures in the body. The various resonance relationships examined, including between the brain and gastric neurons, brain and sensory organs, and brain and spinal cord, generally match the predicted SSR relationships, empirically supporting this principle of GRT.

The effect of low-frequency electromagnetic field on human bone marrow stem/progenitor cell differentiation. The plasma membrane is often considered to be the main target for EMF signals and most results point to an effect on the rate of ion or ligand binding due to a receptor site acting as a modulator of signaling cascades. Ion fluxes are closely involved in differentiation control as stem cells move and grow in specific directions to form tissues and organs. EMF affects numerous biological functions such as gene expression, cell fate, and cell differentiation, but will only induce these effects within a certain range of low frequencies as well as low amplitudes.

How to control proteins with light in living systems. The possibility offered by photocontrolling the activity of biomolecules in vivo while recording physiological parameters is opening up new opportunities for the study of physiological processes at the single-cell level in a living organism. For the last decade, such tools have been mainly used in neuroscience, and their application in freely moving animals has revolutionized this field. New photochemical approaches enable the control of various cellular processes by manipulating a wide range of protein functions in a noninvasive way and with unprecedented spatiotemporal resolution.

Science is increasingly looking at cell biology with the eyes of physics and electronics, providing compelling evidence that life is embedded within oscillatory patterns that create coherent rhythms, now recordable at cellular, subcellular, and even molecular levels. In addition to expressing rhythmically their molecular dynamics, cells are able to organize their decisions and fate by detecting and deploying the physical energies that permeate nature, including extremely weak mechanical vibrations (nanomotions), magnetic fields, and electromagnetic radiations (light).
Physical energies to the rescue of damaged tissues. Rhythmic oscillatory patterns sustain cellular dynamics, driving the concerted action of regulatory molecules, microtubules, and molecular motors. We describe cellular microtubules as oscillators capable of synchronization and swarming, generating mechanical and electric patterns that impact biomolecular recognition. We consider the biological relevance of seeing the inside of cells populated by a network of molecules that behave as bioelectronic circuits and chromophores. We discuss the novel perspectives disclosed by mechanobiology, bioelectromagnetism, and photobiomodulation, both in term of fundamental basic science and in light of the biomedical implication of using physical energies to govern (stem) cell fate. We focus on the feasibility of exploiting atomic force microscopy and hyperspectral imaging to detect signatures of nanomotions and electromagnetic radiation (light), respectively, generated by the stem cells across the specification of their multilineage repertoire. The chance is reported of using these signatures and the diffusive features of physical waves to direct specifically the differentiation program of stem cells in situ, where they already are resident in all the tissues of the human body. We discuss how this strategy may pave the way to a regenerative and precision medicine without the needs for (stem) cell or tissue transplantation. [PMC6600852]
Editorial: Cardiovascular physiology and pathology of cardio-pulmonary and peripheral sensory nerves. The cardiopulmonary system is endowed with a variety of sensory receptors that are necessary for cardiovascular homeostasis. For the most part, stretch receptors in the heart, lungs and great vessels participate in classical negative feedback reflexes to regulate blood pressure, blood volume and in the case of chemoreceptors oxygen and carbon dioxide tension. The peripheral and central pathways of many of these receptors are vagal or glossopharyngeal. On the other hand, there are a separate group of receptors whose axons enter the central nervous system through the dorsal root ganglia accessing the spinal cord and ascending through the dorsal columns to evoke excitatory responses, especially via the sympathetic nervous system.

An Effective Method for Acute Vagus Nerve Stimulation in Experimental Inflammation. Neural reflexes regulate inflammation and electrical activation of the vagus nerve reduces inflammation in models of inflammatory disease. These discoveries have generated an increasing interest in targeted neurostimulation as treatment for chronic inflammatory diseases. Data from the first clinical trials that use vagus nerve stimulation (VNS) in treatment of rheumatoid arthritis and Crohn's disease suggest that there is a therapeutic potential of electrical VNS in diseases characterized by excessive inflammation.

A novel conceptual framework for the functionality of the glymphatic system. The glymphatic system is responsible for the clearance of the potentially harmful metabolic waste of the Central Nervous System. Slow-wave sleep is important for glymphatic clearance due to neuronal electromagnetic synchronization and expansion of the interstitial space. Therefore, sleep and vascular disorders, as well as ageing, may hinder glymphatic flow and induce a noxious milieu of susceptibility to neurodegenerative disorders because of metabolic waste accumulation. We lastly introduce a new idea postulating that electromagnetic induction may constitute one of the propelling forces for the convectional current and mixing of CSF and ISF. PMID: 37073982.
Biophoton transfer along the nerves of rats has been demonstrated experimentally. Different spectral light stimulation (infrared, red, yellow, blue, green and white) at one end of the spinal sensory or motor nerve roots resulted in a significant increase in the biophotonic activity at the other end. Such effects could be significantly inhibited by procaine (a regional anaesthetic for neural conduction block) or classic metabolic inhibitors, suggesting that light stimulation can generate biophotons that conduct along the neural fibers, probably as neural communication signals. The mechanism of biophotonic conduction along neural fibers may be mediated by protein-protein biophotonic interactions.

This research provides some insight into how the various types of healing sound Qigong might work.
Multiple Integrated Complementary Healing Approaches: Energetics & Light for bone. A synergistic-healing strategy that combines molecular targeting within a system-wide perspective is presented as the Multiple Integrated Complementary Healing Approaches: Energetics And Light (MICHAEL). The basis of the MICHAEL approach is the realization that environmental, nutritional and electromagnetic factors form a regulatory framework involved in bone and nerve healing. The interactions of light, energy, and nutrition with neural, hormonal and cellular pathways will be presented. Energetic therapies including electrical, low-intensity pulsed ultrasound and light based treatments affect growth, differentiation and proliferation of bone and nerve and can be utilized for their healing benefits. However, the benefits of these therapies can be impaired by the absence of nutritional, hormonal and organismal factors.
Electromagnetic homeostasis and the role of low-amplitude electromagnetic fields on life organization. The appearance of endogenous electromagnetic fields in biological systems is a widely debated issue in modern science. The electrophysiological fields have very tiny intensities and it can be inferred that they are rapidly decreasing with the distance from the generating structure, vanishing at very short distances. This makes very hard their detection using standard experimental methods. However, the existence of fast-moving charged particles in the macromolecules inside both intracellular and extracellular fluids may envisage the generation of localized electric currents as well as the presence of closed loops, which implies the existence of magnetic fields. Moreover, the whole set of oscillatory frequencies of various substances, enzymes, cell membranes, nucleic acids, bioelectrical phenomena generated by the electrical rhythm of coherent groups of cells, cell-to-cell communication among population of host bacteria, forms the increasingly complex hierarchies of electromagnetic signals of different frequencies which cover the living being and represent a fundamental information network controlling the cell metabolism. From this approach emerges the concept of electromagnetic homeostasis: that is, the capability of the human body to maintain the balance of highly complex electromagnetic interactions within, in spite of the external electromagnetic noisy environment. This concept may have an important impact on the actual definitions of heal and disease.
The coming age of Electroceuticals - Michael Levin
Fields of the Cell: An open-access eBook published by Resaerch Signpost in 2015. Editors: Fels D, Cifra M, Scholkmann F Abstract Cellular electrophysics might become an increasingly important branch in biology and medicine because it offers new insights to old issues, e.g. about development/embyrogenesis or cell signalling, and generates new questions, e.g. on the role of external physical fields in the context of the organism‘s development and evolution.

The field of electroceutical and bioelectric therapy is recognized as the main modality of mental health treatments along with psychotherapy and pharmacotherapy. Electroceutical and bioelectric therapy comprises electroconvulsive therapy (ECT), vagus nerve stimulation (VNS), repetitive transcranial magnetic stimulation (rTMS), deep brain stimulation (DBS), transcranial electrical stimulation (tES), and other brain stimulation techniques. This review provides a comparison of existing electroceutical and bioelectric techniques, primarily focusing on the therapeutic advantages and limitations of each therapy in the current electroceutical and bioelectric field. PMID: 36700309.
Bioelectric Fields at the Beginnings of Life. In this article, we suggest that a missing factor in origins of life theories is that a flow of ions, for instance in a deep-sea thermal vent, generated an electric field, which led to a far from equilibrium dissipative self-organizing structure and a prototypical morphogenetic field putting bioelectricity center stage in the origin and evolution of life. This might suggest that the smallest quanta of life, at least on this planet, is a self-replicating and adaptive structure capable of maintaining a self-reinforcing biofield that enables the dissipation of an energy gradient, which, critically, holds information about its overall shape. From this perspective, the uncoupling of ion gradients and futile cycling can perhaps be viewed as mechanisms not only to enable dissipation, but also to maintain these fields, and so fulfil the arrow of entropy.

Understanding the Feedback Loops between Energy, Matter and Life. This review gathers recent findings in biophysics that shed light on the biological principle of self-organization, spanning from molecules to more complicated systems with higher information processing capacity. The focus is on "feedback loops" from information and matter to an exchange component with a more fundamental meaning than "cybernetic regulation" and "maintenance of homeostasis". This article proposes that electric and electromagnetic forces are the most important mediators over large distances. Field-like mediation is distinguished from cell-to-cell communication by special electric- or ion-guiding mechanisms that create additional pathways to the "classical" mediators such as nerve conduction or blood flow. Resonance phenomena from phonons and photons in the visible range will be discussed in relation to organelles, cytoskeletal elements and molecules. In this context, the aqueous surrounding of molecules and cells is an important aspect. Many of these phenomena are caused by quantum physics, such as the tunneling of electrons in enzymes or in other coherent working systems. This suggests that quantum information processing is also spread over large-scale areas of an organism. PMID: 36575844.
Cell Responsiveness to Physical Energies: Paving the Way to Decipher a Morphogenetic Code. Increasing and compelling experimental evidence show that biology is fashioned and regulated not only by chemical signaling, but even by multifaceted physical energies, including mechanical waves, electric patterning and gradients, as well as electromagnetic radiation, which also includes light. This paper highlights the fundamental role of physical forces in cellular decisions, stressing the intriguing similarities in early morphogenesis, tissue regeneration, and oncogenic drift. Biological patterns are strongly embedded in the vibrational nature of the physical energies that permeate the entire universe. We describe biological dynamics as informational processes at which physics and chemistry converge, with nanomechanical motions, and electromagnetic waves, including light, forming an ensemble of vibrations, acting as a sort of control software for molecular patterning. Biomolecular recognition is approached within the establishment of coherent synchronizations among signaling players, whose physical nature can be equated to oscillators tending to the coherent synchronization of their vibrational modes. Cytoskeletal elements are now emerging as senders and receivers of physical signals, “shaping” biological identity from the cellular to the tissue/organ levels. PMCID: PMC8949133.
Unveiling the morphogenetic code: A new path at the intersection of physical energies and chemical signaling. We discuss the remarkable role of physical energies in the control of cell signaling networks and in the specification of the architectural plan of both somatic and stem cells. In particular, we focus on the biological relevance of bioelectricity in the pattern control that orchestrates both developmental and regenerative pathways. To this end, the narrative starts from the dawn of the first studies on animal electricity, reconsidering the pioneer work of Harold Saxton Burr in the light of the current achievements. We finally discuss the most recent evidence showing that bioelectric signaling is an essential component of the informational processes that control pattern specification during embryogenesis, regeneration, or even malignant transformation. We conclude that there is now mounting evidence for the existence of a Morphogenetic Code, and that deciphering this code may lead to unprecedented opportunities for the development of novel paradigms of cure in regenerative and precision medicine.

The bioelectric code: An ancient computational medium for dynamic control of growth and form. Eight Meridian Theory (see Fabric of the Soul: 8 Extraordinary Vessels) meets modern bioelectricity research. [PMID: 28855098]
According to traditional chinese medicine the eight extraordinary vessels or meridians are the energy template of the body. This energy template or field is affected by the environment and is the fundamental pattern that provides the basis for human growth and morphology. What determines large-scale anatomy? DNA does not directly specify geometrical arrangements of tissues and organs, and a process of encoding and decoding for morphogenesis is required. Moreover, many species can regenerate and remodel their structure despite drastic injury. The ability to obtain the correct target morphology from a diversity of initial conditions reveals that the morphogenetic code implements a rich system of pattern-homeostatic processes. The authors describe an important mechanism by which cellular networks implement pattern regulation and plasticity: bioelectricity. All cells, not only nerves and muscles, produce and sense electrical signals; in vivo, these processes form bioelectric circuits that harness individual cell behaviors toward specific anatomical endpoints. Levin at Tufts is a leader in this field of human bioelectricity research.
Electromagnetic fields as structure-function zeitgebers in biological systems: environmental orchestrations of morphogenesis and consciousness. Biological systems are subjected to an ever-present influence: the electromagnetic (EM) environment. Biological systems have the potential to be influenced by subtle energies which are exchanged at atomic and subatomic scales as EM phenomena. These energy exchanges have the potential to manifest at higher orders of discourse and affect the output (behavior) of a biological system. [PMCID: PMC4224074]
Endogenous Bioelectric Signaling Networks: Exploiting Voltage Gradients for Control of Growth and Form. Traditional Chinese Medicine's Eight-Meridian (or Extraordinary Vessel) theory describes the formation and flow of energy through the body. Qi follows Eight Extraordinary vessels which comprise an energetic blueprint of the body. Among other things, these vessels are responsible for growth, development, and aging. Developmental bioelectricity is an emerging discipline that researches endogenous bioelectric signaling among many cell types to regulate pattern formation. Bioelectriciity is responsible for the dynamic control of complex anatomy and its growth and developmental transformations through aging. The authors especially note the possibilities of studying ionic activity in the brain to better understand the function of bioelectricity. [PMID: 28633567]
Epithelial Tissue Geometry Directs Emergence of Bioelectric Field and Pattern of Proliferation. Mechanotransduction triggers the formation of bioelectric gradients across a tissue, which are further translated into transcriptional changes that template patterns of growth. [PMID: 32520653].
Where have the organizers gone? - The growth control system as a foundation of physiology. A model of growth control system suggests that the organizers in embryogenesis continue to exist and partially retain their function after embryogenesis. The organizers are the macroscopic singular points of the morphogen gradient and bioelectric fields. They have higher metabolic rate, higher density of gap junctions and stem cells than the surrounding tissue. The growth control model predicts that the organizers are likely to exist at the extreme points of surface or interface curvature of the body. Changes in bioelectric field at organizers precede the morphological and anatomical changes in morphogenesis and pathogenesis. Subtle perturbations at organizers can cause long lasting systemic effects. These features of organizers can be used for diagnostic and therapeutic purposes such as regenerative medicine. There is increasing evidence that acupuncture points are likely to have originated from organizers in embryogenesis. Many corollaries and predictions of the growth control model have been independently confirmed. The growth control system is embedded in various physiological systems and is part of the foundation of physiology and pathophysiology. [PMID: 27634622].
