is a light/sound machine?
light and sound pulses at a specified frequency, these machines stimulate
the mental activity in various ways, essentially leading perception from
the waking state to a variety of altered states of consciousness.
are some examples of "altered states of consciousness" and
how do they differ from normal states?
state: attention directed to surroundings. Includes agitated,
restless/"monkey mind" states which are especially amenable
to treatment with light and sound stimulation.
state: Relaxed, tranquil, daydreaming, "inward awareness"
state. Light meditation here, too.
or "twilight" state: Borderline sleep; deep meditation
state; hypnotic state; access to the unconscious mind and enhanced retrieval
of memories; creativity, accelerated or "superlearning", inspiration.
Associated with increased theta brainwave activity
state: Deep, dreamless sleep; deep rest. Often associated
with increased delta brainwave activity
can benefit from this technology?
and sound is an effective tool for anyone who wishes to explore altered
states of consciousness, awareness expansion and sensory stimulation,
psychedelic-like visual imageray, and those seeking an entertaining path
there anyone who should not use this technology?
everyone who uses light and sound stimulation report enjoying it.
However, if you have a family history of epilepsy, are taking psychoactive
medication or have ever had a seizure of any sort, we recommend consulting
your physician before using light and sound. Likewise, if bright
light bothers you (i.e., can give you a headache), then light and sound
may not be for you.
happens during a session?
special light-bearing sunglasses over your closed eyes and headphones
over your ears, you are immersed in colorful dancing geometric patterns
and entrancing sounds. The light and sound pulse rate shifts from state
to state as the session progresses; mental activity will follow the pulse
rate of the machine.
is achieved by experiencing these states of consciousness?
following are some of the areas being explored by users of these machines:
psychological stress relief, deep relaxation, assistance in falling asleep,
memory improvement, increased learning, stabilizing emotions, increased
intellectual focus, lucid dreaming, sensory stimulation, and increased
physical energy. While some of these benefits have been substantiated
by research studies, these machines are experimental and results will
vary from person to person.
important is sound to the overall experience?
and music have been used for centuries in many cultures to alter consciousness.
Drums, chants, and environmental sounds like wind and rain all provide
strong mental pictures and associations. Pleasant sounds are much more
enjoyable and relaxing than one-note beeps or tones, such as those used
by other machines. Synetic Systems incorporates the most sophisticated
sound generation circuitry of any light/sound device, employing digital
wavetable synthesis to generate complex wave forms, rich two- and three-note
harmonies, and moving audio sculptures. Use of special AudioStrobe®
CD's can fully synchronize the lights with the audio program. However,
because a much larger portion of the brain is involved in vision as compared
to audio processing, we can state that sound is less important than the
lights as a means for achieving the desired states.
are "binaural beats"?
beats occur when two sine (pure) waves of slightly differing frequency
are presented to the left and right sound channels: the difference
between the left and right is synthesized by the brain and perceived
as a slowly modulated frequency. This is known as a binaural beat frequency.
This beat frequency is typically modulated at the same frequency as the
are LEDs used instead of incandescent lights?
emitting diodes–LED's–are state of the art solid state devices
that convert small amounts of electrical energy into light. They can be
switched on and off much faster than incandescent lights, producing the
crisp strobe-like pulses which have been shown to be most effective at
inducing desired patterns of activity. They also create very pure colors–again
an important factor in the alteration of consciousness, as demonstrated
by several published studies.
is "wavetable crossfading"?
includes four different, user-editable audio waveforms. The waveform,
pitch etc. can change from segment to segment, and to avoid a startling
"hop" from one to the next, we smoothly mix them together at
the segment boundaries; this is called "crossfading".
describes our biofeedback/light and sound interlink protocol, which enables
the automatic, real-time control of light/sound sessions from certain
biofeedback systems, such as ThoughtStream™.
patterns of our response to emergencies probably emerged during the time
when all humans faced actual physical threats to their survival. Although
the "threats" we now live with are seldom physical, the body
still reacts as if they were.
and perceived stressful events can produce strong emotions, which arouse
certain physical responses from the sympathetic nervous system - the network
of nerve tissues that helps prepare the body to meet emergencies by "flight
or fight." Some of us are more sensitive to the flight-or-fight response
we sense danger, our bodies release stress hormones, and our heart rate,
blood pressure, and muscle tension increase. While this response is useful
when we really are in danger and need to respond, it can be a problem
if we do not learn how to respond to ordinary stresses in a healthy way
and can lead to feeling chronically "stressed."
thoughts, and feelings influence our whole mind/body system. Individual
physical responses to stress can become habitual. When the body is repeatedly
aroused, one or more functions may become permanently overactive. Become
more aware of your responses, and you can be more comfortable and in control
- you can learn to change inappropriate reactions.
is Galvanic Skin Response (GSR)?
Fluctuations in the skin's electrical resistance often associated with
emotional states. The ThoughtStream™
personal GSR biofeedback system measures tiny, rapid fluctuations in skin
moisture associated with the degree of arousal via a compact palm sensor
presents these changes to you by both audio and visual means. You learn
to lower the pitch of a sound heard through headphones or make the LED's
on the display console turn from red to green. For more comprehensive
training use the included Mental
Games multimedia software to fine-tune your ability
to relax and focus at the same time.
