Bioelectromagnetics
is a
relatively new interdisciplinary science at the interface between
biology,
physics and medicine. The spectrum of modern bioelectromagnetics
research
runs from concrete applications, such as therapeutic applications of
electromagnetic
(EM) fields, to studies that seek to reveal how living cells, tissues
and
organisms can usefully interact with EM signals. Therapeutic
applications
include the EM stimulation of wound and bone healing, the use of
magnetic
pulses to alleviate arthritic conditions, and the treatment of sleep
disorders
and anxiety with electrical currents.
In this
presentation, I
will highlight key aspects of modern bioelectromagnetics, and discuss
new
findings and future research directions. Additionally, I hope to
stimulate
thinking about the relationship, if any, between EM bioenergy and
unconventional
"subtle energies" concepts. Normally this question lies outside the
scope
of bioelectromagnetics research, although it is possible that
bioelectromagnetics–in
conjunction with the new science of complexity–may yet provide a
scientific
framework for studying so-called "subtle energy" therapies. Since we
are
covering such a wide field, I’ll begin with a brief overview to
introduce
some common terminology, and to draw important distinctions.
Electromagnetic
Vibrations
and Energy Medicine
Electromagnetic
energy surrounds
us all of the time. Throughout the entire process of evolution, all
organisms
have grown and developed in the presence of EM fields. We are immersed
in all sorts of EM energies covering the spectrum from the Earth’s
geomagnetic
field, radio frequencies and microwaves, to visible light, all the way
up to cosmic rays. It should be no surprise, therefore, that organisms
have adapted to use EM fields in important ways as part of their normal
physiological functioning. Such phenomena are increasingly being
studied
in laboratories today. If organisms, including human beings, have
naturally
adapted to environmental EM energies and make use of them in their
normal
physiological functioning, it makes sense to inquire: Can such energies
be controlled and used for healing?
As in any new and
growing
scientific field, terminology differs from group to group. Medical
applications
of EM energy are variously called "energy medicine", "electromedicine",
"electrotherapy", or "magnetotherapy". These are all terms used among
different
healing practitioners, ranging from conventional medics to alternative
healers. The term "energy medicine" is often used as an umbrella to
cover
the whole range of therapeutic modalities.
The modern era in
bioelectromagnetics
started only about three decades ago, although efforts to use EM
signals
in therapy have a much longer history. Beginning in the 1960s, there
has
been a growing interest in the possibilities of applying EM fields and
radiation to treat a variety of health conditions–cancer, immune
defects
or bone fractures, for example–and now there are even claims that EM
fields
may be used in AIDS therapy. Many scientists still believe, however,
that
weak EM fields cannot have significant effects on human physiology, not
to mention the power to heal. They say that the energies involved
appear
to be far too weak to be able to trigger any biological responses.
Besides
the experimental challenges to investigating bioelectromagnetics, the
major
problem is the continued absence of a thorough scientific foundation.
This
represents the single most important obstacle in developing effective
EM
treatments, and for achieving mainstream scientific acceptance.
The Scientific
Approach
Thousands of
research reports
have been published by Eastern and Western scientists on
bioelectromagnetic
effects. I should point out, however, that although these reports have
raised many hopes for possible therapeutic applications, so far only
few
such EM applications have begun to find their way into the clinical
setting.
Basic laboratory studies include the investigation of EM effects on:
• the nervous
and endocrine
systems;
• muscular-skeleton
system,
especially on bone growth and the prevention of osteoporosis;
• the immune
system;
• carcinogenic
processes;
• reproduction and
development;
• wound healing;
• psychological
parameters
(cranial electrostimulation therapy, for example, uses EM fields to
treat
withdrawal symptoms in drug abusers).
The independent
confirmation
of laboratory results–a prerequisite for scientific progress–still
poses
a great challenge to scientists in the field. As a result, the
replication
of findings and the use of strict experimental protocols has become a
primary
concern in bioelectromagnetics.
My own work at
the VA
Medical Center in Loma Linda addresses how EM signals interact with the
immune system. Our ultimate goal is to identify EM signals which
are
capable of stimulating the body’s immune system and, therefore, can be
externally applied to boost immune activity. Our current focus is to
develop
new methods for measuring the impact of EM energy signals on
bioregulation.
With our techniques we now can directly observe the often subtle field
effects on living immune cells at the very moment the EM field is
applied.
This enables us to identify the most effective EM signal frequencies,
intensities
and signal combinations.
Searching for
Answers
As this field opens
up,
some important questions need to be addressed:
• What is the
physiological
role of EM signals generated by organisms internally?
• Besides regulating
nervous
and muscular activity, what other body systems are controlled by EM
energy?
• What field
distributions
and organization occur naturally within the body, and what is the
nature
of the body’s own EM signals?
• What kind of
measurable
signals are emitted from the body? (For decades, we have used EM
emissions
for diagnostic purposes by mapping EM fields associated with brain
[EEG]
and heart activity [EKG].)
• What is the role
of the
body’s internal EM fields, specifically in the self-healing
process?
• Could part of the
body’s
healing system be controlled by bio-information encoded in EM
signals?
Insights into this
last area
could dramatically improve the effectiveness of energy medicine and
possibly
other alternative modalities.
One approach to
studying
these questions would be to look at the extraordinary sensitivity of
some
animal species to weak electric and magnetic signals. Sharks, for
instance,
can detect electric fields in sea water on the order of a few
billionths
of a volt per centimeter. That’s a tiny amount: Picture placing the
plus
pole of a standard 1.5-volt battery in the sea off San Francisco and
the
minus pole off San Diego–a shark would be able to detect the
intervening
electric field. We have an explanation for such sensitivity with
sharks.
During their evolution over hundreds of millions of years, they used
electric
fields in the ocean for navigation and to detect prey. In sharks and
other
fish, biological EM detectors have evolved that enable them to respond
to minute signals.
However, in humans
we have
no clear idea of what or where EM detectors would be. One fascinating
observation
is related to the pineal gland–often associated with the "third eye" in
mystical literature. Laboratory studies demonstrate that this brain
gland
is sensitive to field levels matching the strength of the Earth’s
magnetic
field. In fact, when the natural EM environment fluctuates with weather
changes or sunspot activity, statistical analyses show above-chance
correlations
with human disturbances such as epileptic seizures or traffic
accidents.
Something seems to go wrong in the brain–possibly via the pineal gland.
This evidence is purely statistical; it has not yet been confirmed in
the
laboratory.
Magnetic
Crystals
Research has now
confirmed
the presence of small magnetic particles in living cells, and these
could
possibly act as natural magnetic detectors. Samples of human immune
cells
(leukemic T-cells) were found to respond to magnetic fields in
experiments
my colleagues and I conducted at the VA Medical Center in Loma Linda.
When
Dr. Kirschvink, at the California Institute of Technology in Pasadena,
analyzed these cells, he confirmed the presence of tiny magnetic
crystals,
called magnetite.
This was the first
hint
that there might be detectors in the human body that could explain the
sensitivity of the immune system to EM fields. Previously, Kirschvink
and
his colleagues had also discovered magnetite in the human brain,
providing
a possible basis for interactions between EM fields and the brain.
The Next
Frontier in Bioelectromagnetics
It is almost certain
that
present bioelectromagnetic theories alone cannot account for all
alternative
medical practices which claim the involvement of "subtle energies".
Practices
such as acupuncture, healer-healee interactions (as in qi-gong,
"therapeutic
touch"), bio-resonance therapies or homeopathy are used by tens of
millions
of Americans. Patients feel, in many cases, that these treatments work
better for them than the conventional therapies. Their use is spreading
despite the lack of substantial laboratory evidence to prove unusual
energetic
interactions.
Mainstream medicine
remains
skeptical of these modalities. Not only is there a lack of convincing
laboratory
evidence, but the relationship is unclear between unconventional
"subtle
energies"–such as ch’i in traditional Chinese medicine, prana in the
ancient
Indian medical system, the vital force of Hahnemann’s homeopathy, or
the
novel bioenergy concepts proposed by Russian scientists–and the EM
signals
studied in bioelectromagnetics. Definition of terms is also a problem:
There is no consensus on what is meant by "subtle energies". Are they
electromagnetic
in nature? Are they highly organized and complex EM patterns which, so
far, can be decoded only by living organisms? Are they at all related
to
the known physical forces such as electromagnetism? No one knows for
certain.
These questions
raise deep
issues regarding the nature of "subtle energies" and
bioelectromagnetism
(not to mention the nature of electromagnetism itself). At this level
of
questioning we encounter the interface between physics and metaphysics.
But since we are concerned here with the scientific investigation of
possible
"subtle energies", it will be helpful to distinguish between three
radically
different philosophical approaches to biology: vitalism, reductionism
and
emergentism.
Ever since the
Western scientific
study of life and health began about two and a half thousand years ago
with Aristotle, two opposing views on the nature of life have vied for
acceptance: vitalism and reductionism.
• Vitalism:
The Belief
in a Universal Life Force
The notion of a
vital force
(a special force which endows matter with the properties that are
unique
to living systems) is the subject of vitalistic philosophies of biology
and medicine. Vitalism introduces the notion of a metaphysical form of
energy or a causal factor that is unique to living matter.
Consequently,
vital forces must exist outside the realm of conventional physical
forces,
including electromagnetism. On the other hand, a more recent
interpretation
of vitalism–called neo-vitalism–denies the existence of a life energy
of
metaphysical origins. Instead, neo-vitalists argue that the phenomena
of
life must be due to a new physical force still undetectable with
existing
technology.
• Reductionism:
Successes
and Limitations
In contrast to all
forms
of vitalism, reductionism maintains that animate and inanimate matter
basically
consist of the same materials and are subject to the same physical laws
and forces. Radical reductionists believe that biomedicine can
ultimately
be reduced to physics and chemistry at the microscopic level of atoms
and
molecules. Accordingly, many scientists believe that medicine can
eventually
be reduced to molecular biology–"all life is chemistry" is an example
of
this view. Without a doubt the reductionist approach of mainstream
biomedicine
has proven highly successful in some areas. The promise of gene
therapy,
for example, where the repair of a chemical defect in a DNA molecule
remedies
an otherwise fatal physical condition, makes a convincing case for the
power of molecular reductionism.
But there are limits
to
the explanatory power of the reductionist view–because the complexity
of
organisms confounds this approach. Organisms are not simply made up of
large numbers and varieties of molecular components but, most
important,
these "parts" are highly organized and often involve unpredictable
interactions
and interrelationships. Biological function, including the restoration
and maintenance of health, depends on this interconnectedness. The
capacity
of living matter to organize itself into highly coherent, dynamic
structures
during development or regeneration is an example of an organism’s
dynamic
and emergent complexity. Reductionist mechanical models cannot cope
with
the immense complexity of organisms, nor explain the spontaneous
emergence
of self-organizing properties in living systems. A third possibility is
now gaining attention and momentum in biology: emergentism.
• Emergentism:
The New
Science of Complexity
Emergentism neither
invokes
an unknown immaterial vital force, nor agrees with the reductionist
position
that life processes can be completely deduced from physico-chemical
laws.
Computer models, based on nonlinear dynamical concepts used in
complexity
theory, have already provided fascinating results. For example, some
models
show that qualitatively new properties, which would be essential to
life
and health such as self-organization, can spontaneously emerge from the
nonlinear interaction of the old properties. Remarkably, the models
also
demonstrate that the phenomenon of self-organization itself cannot be
explained–not
even in principle–based on the previous properties. Reductionism would
be unable to account for this observation.
These results also
indicate
that no special vital force is needed to account for the irreducible
complex
behavior of living organisms. This insight is of great significance
because
vitalism has always rejected the idea that the capacity to
self-organize,
a seemingly fundamental quality of animate matter, could spontaneously
emerge on the basis of physical laws alone.
Emergentism may
finally
be putting an end to the historical conflict between (neo)vitalists and
reductionists. The new science of complexity, with its ability to
describe
spontaneously emerging qualities, recognizes that the whole must not be
broken down into its constituent parts in order to account for
previously
unexplainable properties of life. Therefore, emergentism may form the
foundation
of an adequate epistemology for biology and medicine. Importantly,
since
emergentism represents a kind of non-vitalistic holism, it could also
provide
a holistic scientific framework for biomedical research in general, and
for bioelectromagnetics in particular.
Subtle
Energies or Subtle
Interactions?
Given the new
perspective
of emergentism, we now can see why vitalistic or neo-vitalistic "subtle
energies" have been proposed throughout history. It simply seemed
unimaginable
that the emergence of self-organizing features in matter could occur in
the absence of a special vital force. However, complexity theory now
shows
us that this kind of emergence is indeed possible. More importantly,
the
sensitive dependence of this process on subtle microscopic interactions
opens up a whole new possibility: The question of "subtle energies" may
ultimately become a question of "subtle interactions" of
electromagnetism–in
all possible forms–with the organism. This new vision may provide a
more
powerful framework for research than previous approaches.
In line with this,
one can
speculate that subtle nonlinear EM interactions at the microscopic
level
may give rise to unexpected healing responses at the level of the whole
organism. Could it be, then, that alternative therapies and healing
systems
have learned to utilize this potential, whereas mainstream medicine
remains
unaware of it? In my view this possibility deserves further
exploration.
Seen from this angle, the mystery associated with "subtle energy"
therapies
would be a consequence of our lack of understanding of the complexities
and subtleties in the organization of living matter.
Further, we don’t
know yet
how bio-information, carried by exceedingly weak and possibly highly
organized
complex EM patterns, could be detected, decoded and processed by the
organism.
Bioelectromagnetics, in combination with the new science of complexity,
may help provide some of the answers. The exploration of this
possibility
and its application to clinical therapy will pose an exciting challenge
to future generations of bioelectromagnetics researchers. The potential
rewards for medicine could be immeasurable.
