Introduction
Audio Visual Stimulation (AVS) Technology plays a large role in the
cognitive revolution that is sweeping through the 21st century. Although
the use of sound and or light for healing, relaxation and achieving
altered states of consciousness (ASC) has been used for centuries, it’s
only recently that the scientific community has reawakened to its
phenomenal potential.
AVS Technology is related to EEG Neurofeedback and Biofeedback
technology. While EEG Neurofeedback is more of a precise system of
brainwave stimulation (BWS) reading and delivery, AVS provides a more
general application of BWS. EEG Neurofeedback is also much more
complicated of a system to work with and as a result it requires
specialized, extensive training for usage. Not to mention EEG
Neurofeedback is also a much more expensive system to work with. The
good news is that you can achieve similar results, though more general
with an AVS system and if you decide to go into the field of EEG
Neurofeedback, you will have learned much of the information through
your study and experience with AVS technology.
There is a difference between biofeedback and AVS. Biofeedback is used
to condition the nervous system, while AVS stimulates specific patterns
of activity in the brain. With biofeedback you become aware of processes
normally unavailable to conscious inspection. The awareness includes
understanding how it feels to increase or decrease the selected process
(a state of relaxation or arousal). In the end, both will get you to the
same destination but the journey differs.
In
this module, we will focus on using AVS for brainwave entrainment.
Benefits of Using AVS (Audio Visual Stimulation)
Although results vary with the individual, the results on a whole have
been favorable. Some of the benefits of sound and light
brain entrainment reported are:
-
Increases
in I.Q. especially in children with ADD
-
Improved
memory and attention span
-
Reduction
of stress
-
Better
results in meditation (deeper trance achieved)
-
Pain
management and relief
-
Addiction
relief
-
Replace
lost sleep, reduce fatigue
-
Higher
scores on tests
-
Improved
cognitive ability
-
Accelerated
learning
-
Easier
access to hypnotic state
The more control you can acquire over your brain states, the more
emotional and mental control you acquire over your life.
Brainwave Entrainment

Our senses take in information which is processed by our brain, which in
turn directs our thoughts and emotions. These states of being are
reflected by our brainwaves. When you change your state of mind, you are
also changing your brainwaves. Likewise, if you change your brainwaves,
your state of mind will also change. It is this latter principle that
Brainwave Entrainment is based on.
The Thalamus acts as a pacemaker of sorts, giving cues to the cortical
neurons to fire in a particular pattern (or frequency). The neurons then
synchronize with each other by what is known as the "Frequency Following
Response" (FFR). The FFR is likened to a neurological game of follow the
leader as the cortical neurons fall into harmony with each other. What
is interesting about the FFR is that if an outside rhythm is introduced
then the cortical neurons will synchronize themselves to that beat.
Audio Visual Stimulation (also known as Light and Sound Stimulation) is
a tool that creates a FFR by exposing the brain to a set of desired
frequencies. This is done by means of headphones which deliver the
frequencies through sound and specialized light frames which deliver
similar frequencies though pulsing lights. These external frequencies
act as a neurological pied piper by coaxing the brainwaves to follow
them into a desired state.
"The Frequency Following Response that the mind experiences through
light and sound stimulation provides a focus for the brain. This focus
safely quells any internal dialogue or "brain chatter," and enables the
listener to reach more quickly and effectively the optimum state of mind
targeted for the task at hand (i.e. energizing, learning, relaxing,
etc.)"
Studies have shown light to be a more powerful method of delivery than
sound, however, some people (especially those who are light sensitive)
do respond more favorably to sound entrainment. Sound entrainment is
also useful in situations where light entrainment isn’t possible, such
as if you want to work at your desk.

Brain Wave Frequencies

Brainwave Frequencies overview
-
A
brainwave is an electrochemical rhythm which occurs across the surface of
the brain known as the cerebral cortex. This rhythm measures cortical
arousal which reflects a corresponding state of mind.
-
A
brainwave is measured on the surface of the scalp where all the
bioelectrical activity occurs. The cerebral cortex makes up 80% of the
brain’s mass.
-
This
biochemical electricity is produced in the brain through frequencies
measured in hertz. "Hertz" is measured as beats per second.
-
We
categorize groups of these frequencies according to the range that is
associated with various states of mind.
-
These
frequencies correspond to normally four measurable groups of frequencies –
Beta, Alpha, Theta and Delta. Note: High Beta (24 – 70 Hz) is referred to as
"Gamma". Low Beta (12 – 15 Hz) is referred to as "SMR".
-
Even
though all four frequencies are found in the brain at all times, there will
always be one or two dominant frequencies. Through entrainment, our goal is
to make the desired frequency a dominant frequency at the desired time.
-
When
creating a program, it’s best to use the range of frequencies in the target
area instead of producing segments focusing on one frequency because A)
habituation easily occurs when you only use one frequency, thus making the
treatment less effective, and B) not every person responds the same way to a
frequency. For example, while 10 Hz may produce the desired result in one
person, 11 Hz will produce the same in another person.
Frequency Correspondences

As
you’ll notice from the list below each group of frequencies has its benefits
as well as detriments. Where people get into problems, and this is where AVS
entrainment is most helpful, is when the brain gets stuck in an
inappropriate state. The state is inappropriate because it is either
excessive or deficient in a frequency range or it is producing a range of
frequencies at an inappropriate time (for example, theta when a person is
trying to concentrate).
One of
the most important things to learn about AVS Technology is which states are
associated with what conditions. Having a good working knowledge of this
will make treatment decisions much easier.
The
following frequencies are associated with the following states of mind.
Gamma (High Beta): 25 – 75 Hz
-
Gamma is associated with conscious
perception
-
There hasn’t been much research
conducted in the area of Gamma waves as it was only recently that AVS
machines were capable of generating frequencies in this range.
-
Some claim that Gamma is associated
with the deepest states of meditation relating to that which monks who
train for years achieve.
-
The only frequency group found in
every part of the brain.
-
If you are going to create a
program that has Gamma in it, you’ll want to keep the Gamma segments
fairly brief as too long of a period of Gamma will create anxiety.
Excessive Beta
- Elevated
in all stress-related disorders, some mood disorders, panic, anxiety, fear
and chronic pain.
Beta (Mid Range): 16 – 24 Hz.
-
Training can increase mental ability,
focus, alertness and IQ.
-
18 Hz + - Mental activity, math,
alertness
-
Associated with psychological arousal &
response to threat.
-
Elevated in all stress-related
disorders, some mood disorders as well.
SMR (Low Beta): 12 – 15 Hz.
-
Your brain usually operates at about 13
Hertz when you are relatively calm.
-
Attention, relaxed focus
-
The dominant frequency is Beta when we
are awake, alert and high Beta when anxious.
-
The benefits of Beta training is
improved concentration, cognitive ability and focus.
-
People who have ADD are deficient in
the Beta frequency – and that is why they cannot concentrate or remain
focused. In fact, their brains tend to have Theta as the dominant frequency
and you’d think that this would make them calmer people, not so. Things tend
to work opposite with them; stimulants calm them – which are why doctors
prescribe Ritalin (which is a stimulant). They respond very well to Sound
and Light therapy!
-
Some experiments found that SMR
training can help people with epilepsy reduce seizures. NOTE: A practitioner
should never attempt to treat epilepsy with AVS, unless working with the
patient’s doctor, because with some people AVS exposure induces seizures
instead of curing them.
Deficient in SMR:
- ADD,
stress-related disorders, chronic pain, depression, mood disorders,
psychotic states, substance abuse, panic, anxiety and fear.
Alpha 8-13 Hz
-
Alpha is the first bridge between the
conscious and unconscious mind.
-
Necessary for creativity and positive
thinking.
-
Associated with relaxation and
visualization.
-
Alpha waves are deficient in
alcoholics, their children, individuals with a history of abuse (and their
children) and those with depression and/or anxiety.
-
A person low on Alpha tends to feel
frustration. With no alpha, we lack the conscious ability to express
ourselves because the information from the unconscious to conscious
realization is blocked.
-
The frequencies of Alpha are associated
with harmonization with the Shuman Resonance – the frequency of the earth’s
electro-magnetic field (7.83 Hz. +/- 0.5 Hz.). This is where that feeling of
being connected to the universe comes from because you are in synch with the
universe (at least the earth) at that moment.
-
Conditions that lower Alpha waves:
Hypothyroidism, Hypoglycemia, renal & hepatic disorders.
-
Drugs that increase Alpha waves:
Antidepressants Hydergine and Oxiracetam.
-
Drugs that lower Alpha waves:
Anticonvulsants and Antipsychotics.
-
Best for learning new information,
facts and data. Material that the learner wants to remain in consciousness
and have access to readily.
Deficient in Alpha:
-
People with addictions, chronic pain, stress
disorders, fear, frustration and depression.
Theta: 4 – 7 Hz.
-
Theta is an essential state for
processing information. It is in this state where information is allowed to
enter the long term memory.
-
Alpha/Theta is associated with
learning, creativity and memory.
-
In Theta, the doorway to the
unconscious is open and one is capable of achieving deep spiritual insight.
-
The unconscious governs memories,
sensations and emotions. Theta is the best state to do work in these areas.
-
Theta is a useful state to use in
working with people with PTSD.
-
Childhood memories and repressed
memories can resurface.
-
"…the mind has an innate ability to
release only the amount of information that can be handled and doesn’t pour
everything out all at once and overwhelm the person. And because they are in
a quiet state, people don’t have a flashback or re-experience the trauma,
they become emotional, and they’ll cry but they won’t re-experience. They
process it cortically. Once the memory is reprocessed cortically, in the
conscious mind, the shock to the brain seems to be largely over." (A
symphony in the Brain, pg. 171).
-
In this state, the conscious mind can
be re-scripted.
-
It’s the best state for hypnotic work.
-
Mental fatigue occurs when the ratio
between sodium and potassium are out of balance. 15 minutes in a theta
program helps restore this balance and diminish mental fatigue.
Excessive Theta:
- People
with head injuries and trauma, ADD, ADHD, delusion, poor reality testing,
psychotic states and seizure disorders.
Delta: .5 – 3 Hz
-
Associated with restorative sleep and
healing.
-
Body releases natural opiates. Good
state for pain management.
-
Pituitary releases growth hormone.
-
Delta is predominant in children up to
the age of 4.
Excessive Delta
-
Head injury, coma, fetal alcohol syndrome,
immune disorders, severe substance abuse, severe anxiety and major
vegetative depression.
-
Excessive slow wave activity indicates
attention problems.
Lights

LED Colors
AVS
machines come with different colored LEDs in the light frames. The Procyon’s
light frames contain LED colors: Red, Green and Blue. The Proteus comes with
Red & Green LEDs in its light frames but other colors such as Blue/Red,
White and Blue are available.
Certain colors are associated with particular states and while the LEDs that
come with the machines can produce a combination of colors, it is still good
to have a working knowledge of what colors are best for what circumstance –
especially if you get into writing your own AVS programs.
The
brightness of the lights will increase stimulation and making changes to the
brightness of the lights can aid in increasing attention.
Blue

Amber
Why Light Brightness is varied in a program:
Source: Robert Austin,
creator of Mindplace Products.
-
Changing the color brightness can
change the apparent color (Proteus and Procyon).
-
Brightness is associated with
stimulation, and if the lights are on full all the time, the session may
become too stimulating and not relaxing enough.
-
Changing brightness can help keep the
subject from falling asleep during a session. You may want them to go into a
deep trance but you do not want them to fall asleep.
-
Users should always keep their eyes
closed while running a session and if the light is too bright, they should
turn it down.
Note: Some people are more light sensitive than
others and the practitioner should always check with the client to insure that
the light levels are comfortable before running the session.
Sound

Types of Sounds
Our
hearing is limited to 20 – 20,000 Hz. Notice that most of the important
entrainment frequencies are below what we can actually hear. What is
important to note is that it is the pulse of the tone which creates the
frequency, not the pitch (sound). So what you are actually hearing is the
pitch of the pulsed tone or frequency, not the frequency itself.
There
are basically three types of beats you will hear about: Monaural, Binaural &
Isochronic.
A
Monaural beat is a simple beat like that produced by a drum. Monaural beats
are usually what you’ll find with any music.
An
Isochronic beat is a monaural beat that is evenly spaced. Although, there
have been studies that show binaural beats to be superior to Monaural or
Isochronic, there are many people who favor Isochronic beats and claim to
achieve favorable results using them.
If you
hear a series of frequencies, let’s say through your stereo, your brain will
group the frequencies together or choose a mid point between the frequencies
to entrain to.
Binaural Beats
A
Binaural beat is a perceived beat which is created by exposing one ear to
one frequency and the other ear to a different frequency. The frequency
perceived by the brain is the difference between the two frequencies. So for
example, if you expose one ear to 110 Hz and the other ear to 100 Hz, the
frequency that the brain perceives will be 10 Hz. You can only perceive a
binaural beat if you are wearing headphones or have speakers placed by each
ear. If your left ear can hear what is going into your right ear, you will
perceive the frequency as a monaural or isochronic beat. In order for your
brain to create a binaural beat, it must hear different frequencies in each
ear.
"The
binaural beat is perceived as a fluctuating rhythm at the frequency of the
difference between the two auditory inputs. Evidence suggests that the
binaural beats are generated in the brainstem’s superior olivary nucleus,
the first site of contralateral integration in the auditory system (Oster,
1973). Studies suggest that the frequency – following response originates
from the inferior colliculus. This activity is conducted to the cortex where
it can be recorded by scalp electrodes."
In one
study at the University of Wisconsin-Madison findings indicated that people
with depression had a less active left hemisphere. Given this information, a
possible treatment for depression would be to use an Alpha based program
that uses binaural beats since the nature of binaural beats is to get both
hemispheres working together.
"Dual
BBs will often (but not always) produce monoaural beats as well, since two
tones are present in both ears. One exception is to keep the frequency
relationships set to harmonics, for example, 200 & 400 Hz left and 206 & 412
Hz right.
When
T.B. {Budzynski) was running SynchroMed, we tested several kinds of beats:
binaural, dual binaural and monaural. The BB’s were the only ones which
could cause discernable EEG activation. We were surprised that dual BB’s did
not appear to do so – but the experiment was small.
Dr.
Len Ochs once measured the effect of a constant BB and ramping lights; both
induced EEG activation at their set frequencies. Light produced a stronger
effect than sound."
Re: Pitch variance
Source: Robert Austin
The
pitch of the pulsed tone doesn’t have much (if anything) to do with
entrainment – only the pulse rate. The real reason for varying the pitch for
normal pulsed sound is to provide variety and prevent (or reduce) sensory
habituation, which can occur when the same stimulus proceeds for too long.
Seizures and Medical Warnings

Who
shouldn’t use AVS machines?
People
who have a history of seizures. People who tend to get headaches from bright
lights. Anyone who has a concern should check with their doctor fist.
Products which incorporate flickering light should not be used by
individuals with epilepsy or seizure disorders unless so directed by a
medical doctor. They may also be unsuitable for use by those
taking many forms of psychoactive drugs and those who have suffered from
head injuries.
Photosensitive Epilepsy
PSE is
fairly rare. It affects approximately 1 out of every 14, 000 people.
Watching TV or playing video games tends to set off these seizures. Discos
with strobe lights are definitely out. The longer the exposure to the
source, the more likely a seizure will occur.
People
who are light sensitive or sensitive to certain visual patterns do not have
PSE.
Red is
the most provocative color, while blue is the least.
Not
all epileptics are photosensitive, which means not all epileptics will have
a seizure when using AVS.
Note:
It is still important to take caution when working with epileptics and make
sure you do so under the guidance of their physician.

RE: Children and Seizures
"Children are more likely to have both epileptic and non-epileptic seizures.
Dr. Russell has treated hundreds without a problem (pre-teen to early teens,
mainly), but he’s trained to evaluate the likelihood of such an event.
When
dealing with Teens or Children, it is suggested to have a licensed
practitioner supervise the process; screen for family history of epilepsy,
etc.
Children’s EEGs are slower than adults, and I would make the assumption that
unless there is some aberration which could be possibly treated (a medical
decision), it’s best to find an alternative treatment. (Source: R. Austin,
email: May 22, 2006)
Note:
It should be noted that many children have had seizures from video games and
sometimes watching TV (because of the flicker rate of the screen).

Noteworthy Quotes:
"They (mind devices) are being used by scientists, educators, physicians
and psychologists for everything from accelerated learning & athletic
peak performance training to remediation of chronic medical and
psychological problems. And all of these applications are based on the
simple premise of making the brain more mentally fit – promoting
awareness and control of the basic cycle of cortical relaxation and
activation and the flexibility to move within the cycle at will. Source:

Appendix 2

Misc. Information about AVS, Brain Entrainment etc.
Studying and using AVS:
Study information that you want stored in long term memory before your
AVS session.
After studying, select a Theta based program that is between 30 to 60
minutes. Ideally you want to give your brain enough time to process the
new information thus allowing it to become committed to long term memory
The Schumann Resonance
Dr. Schumann was a physicist in the 50s who discovered that there was an
atmospheric resonance caused by lightening storms.
This resonance is at the frequency of 7.83 Hz and it fluctuates daily
+/- 0.5 Hz.
People associate this "resonance" with being in balance with the earth.
Some call it the "Earth’s Frequency".
Wave Forms
Sine Waves have no harmonic content and tend to elicit following
responses at their frequency alone (though this is not always the case,
as there appear to be "resonant modes in the brain). [R.Austin]
Pulse waves tend to produce harmonics in the EEG, and in fact, both the
rising and falling edges of the light produce visual evoked potentials,
which could either add or interfere with one another (enhancing or
reducing the effective harmonic content). Pulse waves also evoke crisper
visual imagery than Sine. Pulse waveforms are best for energizing
programs and Sine for relaxation. [R. Austin]
Cortical Evoked Response (CER)
- When
stimulus is repeated (above 4 Hz) the brain begins to synchronize to the
stimulus.
Brain
Wave Entrainment is sometimes referred to as: flicker stimulation, photic
driving, cortical evoked response, visual evoked response, variable
frequency photo stimulation, brain wave synchronization, Neurofeedback.
Berger
Effect – When people open their eyes, alpha decreases.

Appendix 3

Qualifying
Research
The
internet can be a good source of information but it can also be a source of
false or misleading information. Many companies that sell products produce their
own research, which can be biased, especially if their "research" concludes
superiority in their product. Their product may very well be a good product but
the research is questionable because there is a conflict of interest between the
research conducted and the company’s interest in promoting their product.
If the
research has been conducted by an independent party who doesn’t stand to gain
financially from the findings (through sales of machines) it is likely that you
will get more valid research. It is acceptable for a company to post those kinds
of results on their web site or in their literature.
Another
thing that often happens is that the research may be valid but the author of the
article has misinterpreted the findings of the research.
Do
not believe everything you see. Look at all research with a skeptical
eye and question anything that doesn’t make sense. My rule of thumb is
to look for more than one (unrelated) source for the information. Make
sure that science, not philosophy or belief, backs the claim made.
Finally, testimonials are not valid research. They have their place,
which is in advertising and sometimes change work, but they are not
accepted in the scientific community as a scientific method of producing
evidence.

Non REM
Sleep is divided into 4 Stages which occur in a 90 minute cycle.
Stage 1:
Transitional sleep. Alpha begins to slow. This stage is fleeting, lasting only a
few minutes.
Stage 2:
Five to fifteen minutes, 12 – 14 Hz, occasional 8 – 14 Hz.
Stage 3:
Delta – EEG = 3Hz
Stage 3
and 4 last around 20 to 40 minutes.
Stage 4:
Delta – EEG = 2Hz or less
The First
sleep cycle = Stage 4 = 20 - 40 minutes.
Lightens
to Stage 2 = 10 – 15 minutes
There is
then a brief period of REM - Beta
The rest
of the night each REM cycle is followed by at least 30 minutes of non-REM.
