SOUND AND LIGHT BRAIN MACHINES
|
|||
|
|
By David C. Freeman
|
|||
|
|
12 September 1991
|
|||
|
|
|
|||
|
|
It has been noted that if one were to strike two tuning forks of
|
|||
|
|
slightly different tone pitch at the same time, one would find that
|
|||
|
|
there were three distinct tones rather than two. The third tone is
|
|||
|
|
the difference in frequency of the two tones. For example, if one
|
|||
|
|
fork resonated at a frequency of 202Hz,(cycles per second) and the
|
|||
|
|
other resonated at a frequency of 200Hz the resulting third tone
|
|||
|
|
would be the difference of the original tone, and would modulate at
|
|||
|
|
2Hz. These modulations are know as beats.
|
|||
|
|
|
|||
|
|
A phenomena was discovered by Dr. Gerald Oster in 1973, at the
|
|||
|
|
Mount Sinai school of Medicine in New York. Dr. Oster had been
|
|||
|
|
investigating the effects of sound waves on the brain. He
|
|||
|
|
discovered that when he introduced, through headphones, two
|
|||
|
|
different tones separately to each ear that the brain would resonate
|
|||
|
|
at a frequency that was the difference of the two tones, ie. 400Hz
|
|||
|
|
introduced to the left ear and 406Hz introduced to the right ear
|
|||
|
|
would result in the a solid EEG (electroencephalagram) reading of
|
|||
|
|
6Hz. He dubbed this phenomena binaural beats.
|
|||
|
|
|
|||
|
|
Before the binaural beat phenomena was discovered, there was no
|
|||
|
|
way to entrain or synchronize brain waves. Studies of brain waves
|
|||
|
|
were limited to the mental state of the test subject, and the waves
|
|||
|
|
that were produced as a result of that state rather than what states
|
|||
|
|
could be produced as a result of altering brain wave frequencies.
|
|||
|
|
|
|||
|
|
Robert Monroe, founder of the Monroe Institute of Applied
|
|||
|
|
Sciences in Virginia, conducted further studies of the binaural beat
|
|||
|
|
phenomena and discovered particular combinations of tones and
|
|||
|
|
frequencies that produce particular effects in humans. Out of the
|
|||
|
|
thousands of possible combinations of frequencies that could be
|
|||
|
|
produced, Monroe and his team settled on fifty three that had
|
|||
|
|
positive strong effects on the brain. Monroe patented this process
|
|||
|
|
in 1975, calling it Frequency Following Response or FFR. Monroe also
|
|||
|
|
developed a tape series designed to utilize the frequency
|
|||
|
|
combinations that he and his team discovered. He called the series
|
|||
|
|
HemiSync, short for Hemisphere Synchronization.

Scientist have generalized the different brain wave frequencies
|
|||
|
|
to indicate what sort of activity the brain is engaged in. The
|
|||
|
|
generalized frequencies are
|
|||
|
|
|
|||
|
|
Beta(13-30Hz);
|
|||
|
|
Alpha(8-13Hz);
|
|||
|
|
Theta(4-7Hz);
|
|||
|
|
Delta(0.5-4Hz).
|
|||
|
|
|
|||
|
|
Beta waves are associated with a "normal" level of arousal with
|
|||
|
|
attention directed externally. High Beta waves are associated with
|
|||
|
|
heavy stress.
|
|||
|
|
|
|||
|
|
Alpha waves are associated with relaxation. Theta waves are
|
|||
|
|
associated with deep reverie, mental imagery, and access to deep
|
|||
|
|
rooted memories. Delta is associated with deep sleep.
|
|||
|
|
|
|||
|
|
Many products have entered the market place utilizing not only
|
|||
|
|
audio FFR, but combining the photic driving response with audio
|
|||
|
|
FFR,(photic driving entails lights flashing at a particular
|
|||
|
|
frequency in the eyes to produce the FFR) to achieve particular
|
|||
|
|
brain states. The majority of the products now on the market have
|
|||
|
|
been approved by the Food and Drug administration (FDA), but what
|
|||
|
|
are the benefits of using one of these devices.
|
|||
|
|
|
|||
|
|
Scientist have discovered that at certain frequencies
|
|||
|
|
(particularly in Alpha and Theta range), the majority of the devices
|
|||
|
|
have been found to:
|
|||
|
|
|
|||
|
|
- alleviate stress
|
|||
|
|
|
|||
|
|
- promote long lasting and substantial reductions in
|
|||
|
|
subjects experiencing anxiety
|
|||
|
|
|
|||
|
|
- facilitate deep physical relaxation and mental clarity
|
|||
|
|
|
|||
|
|
- increase verbal ability and verbal performance IQ
|
|||
|
|
|
|||
|
|
- synchronize both hemispheres of the brain
|
|||
|
|
|
|||
|
|
- invoke vivid spontaneous mental imagery and imaginative
|
|||
|
|
creative thinking
|
|||
|
|
|
|||
|
|
- reduce pain, promote euphoria, and stimulate endorphine
|
|||
|
|
release
|
|||
|
|
|
|||
|
|
Some of the devices that have been tested are:

It is obvious that this technology is in it's fledgling stage of
|
|||
|
|
development and has the propensity to aid many, but where is this
|
|||
|
|
technology going? Will these machines become an industry to parallel
|
|||
|
|
or even surpass the effects that the personal computer has had on
|
|||
|
|
our lives or will future, more powerful advances be put on hold by
|
|||
|
|
the FDA? Only time will tell.
