mid-1930s. Scientists discovered
that the electrical rhythms of the
brain, or brainwaves, tended to assume
the rhythm of a flashing light
stimulus. This process was called
entrainment. For example, when a
strobe light was flashed at a frequency
of 10 Hz into the eyes of a
person monitored by an electroencephalogram
(EEG), the EEG pattern
tended to fall into a 10 Hz frequency.
Various scientists discovered that
such strobe light stimulation could
have a variety of beneficial effects,
such as increasing IQ scores, enhancing
intellectual functioning,
greater synchronization between
the two hemispheres of the brain,
relaxation, improved sleep, pain
relief, and enhanced immune function.
Since these early studies, a
whole new branch of science has
developed called neuroscience,
which includes neurofeedback.
Neurofeedback is based almost
completely on rebalancing the brain
using entrainment techniques. A
way to understand entrainment is
how radios and TVs work. Each
radio or TV station is assigned a
frequency within which it must
broadcast its signals. This way the
signals from all the different stations
do not overlap. The signals
are produced by the broadcast station
transmitters. At the receiving
end, our TVs and radios have tuners
in them. When we change the station
in the radio or TV tuner we
expect the tuner to begin to resonate
in synchrony with the broadcast
signal frequency. Once the signal
is locked in and refined by the
tuner a clear sound and/or picture is
produced. If resonance synchronization
does not happen, then the
picture will be blurry or the sound
will be static noise. The human
brain, nervous system, and for that
matter all the cells in the body, act
like tuners to receive signals from
outside the body. Once the signal is
tuned properly, the body begins to
resonate synchronously with the
signal. Healing PEMFs operate
with this entraining, signal synchronization
process to perform the
desired actions in the body.
Just as sound and light can produce
effects on the body through entrainment,
so too can electrical stimulation
and pulsed electro-magnetic
field stimulation. Generally, whatever
we can do with electrical stimulation
can be done better, more
deeply into tissues and more safely
with PEMF stimulation. PEMF
stimulation can be more effective
because complete penetration of the
entire brain can be achieved safely
with PEMF signals.
While pulsing sound, light, electrical
or electromagnetic fields may
have specific actions on the brain,
or parts of the brain, the commonality
among them is the frequencies
used. So, frequencies used by stimulation
with other technologies
apart from electromagnetic fields
will still have significant stimulation
overlap between them mechanistically,
in particular relating to
the frequencies used. So, research
or experience in using specific
stimulation frequencies with sound,
light, or electrostimulation show
significant comparability in reactions
or even synergies.
One of the goals of PEMF therapy
is to stimulate the nervous system,
in addition to all the other
cells and tissues of the body, to produce
desired health benefits.
Any stable frequency presented to
the body, especially the brain,
evokes a cortical brain response.
The brain synchronizes its own natural
dominant brainwave frequency
with that of the external stimulus.
This is called brainwave entrainment.
