Re: Occult loops

Paranormal Loopheads,

Enjoyed reading Matthias accounts of looping at the healing center,
and Dave's accounts of not realizing when the recording ended and live
natural sounds began.

Matthias asked about synchronizing brain waves with sound.  I did some
investigation and experiments of this nature a few years back. 

The general principle I am aware of is that the brain, when exposed to
stimuli within the range of brainwave frequencies, can change it's
(the brain's) frequency to match the stimulus.  This has been called
entrainment.

I initially encountered this using light as the stimulus.  Though I
had experimented in the 70's with xenon strobes modified to flash
within the beta range.  The strobes I saw at the time had labels
warning NOT to do this, so I had to see why.  The chief problem I had
at the time was that my strobe was not very regular in frequency, it
would drop beats unpredictably.  I did notice interesting visual
patterns and colors when the light was flashing a few inches from my
eyes, with my eyes closed.  What I saw was sort of a geometric grid,
like an infinite tunnel.  The colors would be complementary, say red
and green, or purple and yellow. 

In the 80's I built a personal strobe, using high intensity LEDS
(towards my eyes) on a set of lab goggles.  Using a 555 timer I could
get a more regular frequency, and control the pulse wide of the flash.
 This was interesting, and yielded similar visual patterns with closed
eyes.  The brighter the light, the better the effect.

I found some information about a man making audio tapes that invoked
the entrainment mechanism (using headphones).  Though I never heard
the tapes, I read descriptions of his methods.  As I recall, he put a
tone in one ear, and different frequency tone in the other ear.  This
creates a beat frequency in your head.  The beat exists only in your
head, since the headphones would not allow the two different signals
to exist in the same airspace.  The difference in frequency was the
brainwave frequency you wanted to achieve.  For example, if you want
to achieve 12 hz brain waves, you could have a 400 hz tone in one ear,
and a 412 hz tone in the other.  I am not sure what range of
frequencies he used as the fundamentals.

Generally what I read was that you needed to start the entrainment
near your natural brainwave frequency
at the time, in order for the brain to track with the stimulus.

I never tried to duplicate this effect with sound, but probably have
the tools to do this now.  I did not find the light effects to offer
any practical use.  They were amusing for a while.

Further off topic, I found that there is a device called the mind
mirror that gives you a spectral display of the brainwaves at the 2
hemispheres.  It is a real time analyzer of brainwaves.  This has been
applyed to experienced meditators, and they have mapped the frequency
distribution curves that correlate to particular states of
consciencness.  By using the mind mirror as the feedback, they alledge
anyone can be taught to achieve the states that yogis and others have
taken years to attain by willfully changing your brainwaves to create
the curve that corresponds to the state you desire.
