"mind machines" covers a whole range of technologies
that may work directly or indirectly on your mind or
consciousness. In broad categories, this includes binaural
beat and multi-source hypnosis tapes, light and sound
mind machines, TENS and CES electrical stimulation hardware,
lucid dreaming machinery, neurophones, biofeedback,
and of course the old classic sensory deprivation tanks.
purposes of this revised FAQ, I am mostly ignoring biocircuits,
orgone devices, and radionics, as this compiler remains
unconvinced that any of these things do anything at
all, let alone anything effective.
herbs, nutrients, and drugs are left out of this FAQ
as well, not so much because they aren't effective mind-altering
technologies, but because there is an excellent FAQ
already available, Samu Mielonen's "A Short Introduction
to Smart Drugs" at http://www.uta.fi/~samu/SMARTS2.html.

Research Institute at http://www.ceri.com/.
suppose that you wanted to play, for example, a
5 Hz tone to a person. The human ear doesn't perceive
vibrations at 5 pulses per second as sound, it perceives
them as clicks. So you have to try something else.
Binaural beat works by playing two frequencies,
one into each ear. If one is playing, say, 400 Hz
and the other is playing 405 Hz, then an alert listener
will hear a faint "sweeping" back and forth at about
5 Hz, the difference between the two frequencies.
The resulting frequency is called a binaural beat
frequency. Hemisynch is the Monroe Institute's trademark
for this type of sound effect.
that subliminals are a mostly discredited technology,
we have a new form of hypnotic technology. It's
variously called Ericksonian hypnosis, neurolinguistic
hypnosis, hypnoperipheral processing, paraliminals,
tri-phase induction, and other names. Since as far
as I know, all of the names for this are trademarked,
I'm coining my own term for it: multi-voice hypnosis
(MVH). The basic idea is that at various times during
playback, the user is hearing a different guided
meditation script in each ear.
& sound (L&S) mind machines combine either
pulsed tones or binaural beats (see above) or both
with photic stimulation, which is just a fancy name
for "flashing lights in your eyes."
stands for "transcutaneous electro-neural stimulation,"
or running electricity through the nerves in your
skin. It is a proven technology for controlling
stands for "cranial electrical (or electronic) stimulation,"
or running electricity through your head. In some
cases, the frequencies are quite low, using small
A/C pulses at brainwave frequencies. In other cases,
high frequencies or white-noise random signal generators
are used. At least one of these devices, the Alpha-Stim
100, is US FDA approved for prescription for the
treatment of chronic pain.
dreaming is nothing more or less than taking control
over what happens in your dreams. According to the
Lucidity Institute and others, you can be trained
to do this.
machine is a tool that may aid some people in doing
this. Either a motion sensor or an electro-myelogram
(EMG) detects the rapid eye movements (REM) that
signal the beginning of dreaming, then small red
LEDs blink in front of each eye. Supposedly the
blinking red light will be incorporated into your
dream, and you'll have hypnotized yourself beforehand
to know that a blinking red light means that you're
dreaming, and can alter "reality."
biofeedback systems work on the same principle:
make it possible for the user to see or hear some
bodily process that was hard to monitor before,
and they can try to control it. Hardware exists
to report back skin temperature, galvanic skin response
(GSR), muscle tension via electromyelogram (EMG),
and brainwave frequencies via electroencephelogram
goggles are the least invasive sensory deprivation
devices. The idea is to fill your entire visual
field with an even, featureless, monochromatic light.
You can get various types of goggles that attempt
to do this, or you can just paint a ping-pong ball,
cut it in half, tape the two halves over your eyes
with clear tape, and the look towards the sun or
a halogen light.
tanks or sensory deprivation tanks are
on the other end of the scale in complexity and
expense. The user lies in a light-proof, sound-proof
tank filled with 10" or more of 92° Farenheit water
into which hundreds of pounds of Epsom salts have
been poured so that they float effortlessly, and
stays there with no sensory input other than their
own breathing for four hours or so.
floating is an attempt to replicate some
of the effects of a floatation tank with a modified
waterbed mattress instead.
radionics, subtle energy, chi generators, orgone,
and psionics are all so-called "technologies" for
manipulating the body's psychic energy fields. This
author doesn't usually believe in the existence
of such fields. On the rare occasions that he does,
he doesn't believe that any documented technology
successfully works with or on them. Therefore, he
will not comment on any of the numerous products
that claim to alter or use them.
a variety of possible reasons:
they're cool, cutting edge, novel, interesting, and
fun. Remember, rats who spend their time in a more
stimulating environment grow up to be smarter than
rats who have nothing to play with.
you think that it's your brain, that you have a right
to play with your own brain, and that it's fun to
play with your own brain.
- As an
aid to meditation or reaching meditative states.
you like to have the latest toys before anybody else
you want to see what all the fuss is about.
you believe Michael Hutchison and a few other people
when they tell you that these technologies make you
smarter or whatever.
- As a
legal, non-addictive alternative to getting stoned.
they're part of the cyberpunk lifestyle.
- As an
experimental treatment for some disease.
the most science-ignorant fool thinks that the entire
brain pulses in time to one frequency, EEGs show that
at any given time, the electrical patterns that your
brain produces are made up from distinct wave forms
ranging from 0.5 Hz (pronounced Hertz, or cycle per
second) up to 30 or more Hz. Researchers divide these
frequencies into the following four groupings:
||14 - 30 Hz
||8 - 13 Hz
||4 - 7 Hz
||0.5 - 3 Hz
say that you are "in beta state" (which you normally
are), what we're saying is that that's the dominant
set of frequencies, the ones with the highest amplitudes.
Beta is associated with alertness, with the highest
frequencies in that range often described as "fight/flight"
mode. Alpha frequencies have long been associated with
meditation and relaxation. Theta waves are considered
by some to be associated with a dreamy, creative states.
Delta waves are generally strongest when you're asleep.
frequencies given off by your brain vary from spot to
spot. When the whole brain is dominated by one frequency,
and especially when the two halves of your brain are
in synch, this is called hemispheric synchronization.
studies, meditation, drumming, swimming with dolphins,
binaural beats, photic stimulation, and in some cases
EMG and EEG biofeedback have been shown to alter the
distribution of these frequencies, and sometimes to
encourage hemispheric synchronization. This process
is known as entrainment. How they do
it is subject to debate, but this alteration is usually
attributed to something called the Frequency
or not altering your brainwaves has any effect on your
mind, body, or mood is subject to even more debate.
On one side are the people who insist that stimulating
appropriate brainwaves is "instant Zen," as Zygon advertised.
There are others who insist that brainwaves are just
a scalar wave, noise given off by the brain's mental
and biological processes. Most people on MIND-L fall
somewhere between the two camps.
frequency, the Schumann Resonance,
corresponds to the frequency of certain standing waves
of electrical activity in the upper atmosphere. Although
this phenonemon varies everywhere from 7 Hz to 50 Hz
or more, the number is usually given as 7.83 Hz. Some
mystics who are also users of mind machines insist that
attuning your brain so that the dominant frequency is
7.83 Hz puts you in mystical communion with the planet.
As we say on the net, Your Mileage May Vary (YMMV).
audio tapes and CDs almost certainly don't work, though
there are some people on MIND-L who think otherwise.
Multi-voice hypnosis may or may not
work. They do at least have the advantage over subliminals
in that there is evidence that you can hear them!
There is anecdotal evidence that they can put you
into a trance. I know of no clinical studies showing
long-term efficacy for any purpose.
beats have been shown to alter brainwave
frequencies, for whatever that's worth.
& sound mind machines have also been
shown to alter brainwave frequencies, again, for whatever
that's worth. Most users also find them entertaining,
as they produce fascinating fractal-like light shows
for most users. (See "Why Don't I See Colors?", below.)
and CES have been clinically proven
to be effective treatments for chronic pain, at least
in some patients. Both of them feel weird. There are
some studies suggesting that CES may also be effective
in treating addiction and some other psychiatric disorders.
All other claims are anecdotal, at best.
works for some people and not for others. Long-term
clinical scientific evidence of any benefit is scarce.
deprivation has been demonstrated to be mind-altering,
beyond all shadow of a doubt. Its usefulness for any
purpose is a matter of no little debate.
- Dr. Wilhelm
Reich died in jail, and had all his research notes
seized and burned, for insisting that orgone
devices worked and were useful. That doesn't prove
him right or wrong, but it should give you an idea
of just how scientifically unpopular the idea of radionics,
orgone, and so forth are.
little evidence says maybe yes, and that's as far as
I'll go. See "Are These Things Legal?", below.
Electrical Stimulation, particularly the Alpha-Stim
100, has been shown to be an effective treatment for
some conditions, particularly chronic pain.
there are studies that say that some of these technologies
may have medical uses, but no clear consensus.
If you have,
or think you might have, any illness or medical condition,
seek medical advice. Really. If there is a scientifically
proven medical treatment for your condition, and you
agree with your doctor, then use that. If you want to
use any of the above technologies in addition to an
approved medical treatment, and your physician agrees,
then cool, do that.
the MIND-L mailing list gets a steady stream of requests
for advice on using L&S or CES to treat depression,
bipolar disorder, and ADHD. There are experiments going
on to see if brainwave altering technologies are effective
treatments for these diseases, but there is no final
advocates are routinely accused of hypocrisy, but let
me make myself painfully clear here. With the possible
exception of CES for a small number of conditions, none
of these technologies has been proven to be effective
in the treatment of any disease or medical condition.They
may be in the future. There is certainly research going
on. Your doctor may be willing to prescribe or approve
experimental technologies, but that is between you and
broad limits, yes.
most part, nobody but the Parent's Music Research Center
thinks that listening to any audio tape will hurt you.
On the other hand, if you are particularly suggestible
and you have doubts about using a hypnosis tape, don't
avoid all of these technologies if you are prone to
seizures, or suspect you may have any kind of seizure
disorder. But here's a perfectly good rule of thumb:
if you can stand in front of a strobe light without
discomfort, you probably won't have a problem.
If you have
any kind of depressive, manic, bipolar, schizo-affective,
or attention disorder, then you should probably only
use these technologies under a physician's care and
with your physician's informed approval. We don't yet
know for sure what the effect of tinkering with anybody's
brainwaves will be. Nobody in this field wants to take
blame for what happens to yours.
conflicting studies on whether or not people with chronic
migraines should use these technologies, especially
photic stimulation. There are many doctors who believe
that flickering lights can trigger a migraine. There
are, on the other hand, studies that claim that photic
stimulation can cure migraines. Talk it over with your
physician, and make an informed decision.
And I hope
that it's obvious to even the most idiotic observer
that you should not use any of these technologies while
operating a motor vehicle or any other heavy equipment.
At the very least, they're distracting.
I am not a
lawyer, and the following is not intended as a substitute
for competent legal advice. If you need to know for sure,
hire a real lawyer.
As far as
I can tell, right now, yes, mind machines are legal
in the United States.
understand the legal status of mind machines, you need
to understand the prejudices of the United States' Food
& Drug Administration. The FDA takes the following
principles for granted, and will not consider any evidence
that contradicts them:
that alters body or brain function is a medical treatment.
treatments can and should only be used to cure disease.
medical treatments which have been clinically proven
and widely accepted to be both safe and reliably effective
in curing disease should be used.
normal is not a disease. Anything that promises to
enhance normal human function is at best making a
fraudulent medical claim, and at worst promoting drug
It is the
opinion of this author that all four of those statements
are false and incorrect. Nevertheless, these are the
prejudices of the top several levels of the FDA and
much of Congress, and much of what has happened in mind
machines, vitamins, dietary supplements, and alternative
medicine can only be understood once you understand
So why is
all this stuff legal? Simple. Section 510 of the Pure
Food & Drug Act, the law that created the FDA, specifically
says that they can't ban anything that was already in
use prior to 1976. And in one primitive form or another,
practically all of these technologies existed prior
that, with the one exception of a few approved uses
for CES, none of this stuff is certified or approved
by the US FDA. If that bothers you, go away.
If you care about FDA approval, don't play with or use
mind machines, because the rest of us don't want to
hear you complaining about lack of FDA approval later.
Happened To __________?
all, if you fill in that blank, nobody in the industry
who is in their right mind will comment in public or
for the record. They'd be committing career suicide,
because the FDA doesn't like having their settlements
with various companies discussed.
said, yes, it is true that AlphaLabs, InnerQuest, and
Zygon have all dropped out of the mind machine business,
and Synetics has severely curtailed their operations
in the US.
has authority to go after and shut down any company
that is advertising unwarranted medical claims. This
means that any mind machine company that is making any
medical claims, or anything that the FDA thinks they
can convince a judge is a medical claim, is courting
disaster. A few manufacturers and retailers have spoken
with me off the record, and if they're right, it would
blow your mind to hear some of the things that the FDA
considers a medical claim. Let one example suffice:
if I say, "relax, sit down" then I am practicing medicine
without a license: prescribing a chair as a relaxation
Trade Commission has the authority to go after anyone
whose advertising is false and misleading. If the FDA
can convince the FTC that a manufacturer's or a retailer's
ad is false or misleading, then the FTC will shut them
down. That includes any claim that, according to the
FDA, hasn't been proven.
why everything you see that relates to mind machines
has one or more huge disclaimers on it, saying that
none of these technologies are medical devices or intended
to treat any illness, nor do the manufacturers or the
retailers intend by their representations to prescribe
or treat any medical condition or illness.
don't amount to squat if anything else in the advertising
or other displays contradicts it.
there are a lot of users and a lot of companies that
are very interested in the alternative medicine applications
of mind machines. Which means that those users, retailers,
and manufacturers are lying through their teeth when
they write those disclaimers, just to stay alive. Sometimes
the FDA or the FTC catches them at it.
a shame, because this author actually does
believe in that disclaimer. Other than CES, none of
this technology has been proven
medically effective, yet. It's all experimental, at
But in summary,
other than severe restrictions on how it can be labelled,
advertised, marketed, or sold, yes, so far, all of this
stuff is legal in the United States.
If you live
outside the United States, your law almost certainly
varies, and not being even an American lawyer, let alone
one in your country, I can't help you.
that this is the most important question in the world
to someone who's thinking about plunking down somewhere
between $100 and $6000 for a new tool or toy. But I
hope that you realize the following:
is no machine out there that somebody doesn't love.
Yes, even the Zygon machines.
there is no machine out there that somebody doesn't
hate. Yes, even the Mindwave.
who has spent a lot of money on a product has a strong
personal incentive to convince himself that his machine
is very cool. If he does, then that's what he'll tell
some people just cannot be made happy.
but a handful of dealers has had experience with all
of them. That means that the only people with a broad
basis for comparison are people who have a financial
incentive to convince you to buy the machines with
the highest profit margin.
any consciousness-related matter, you should never,
ever forget Camden Benares' two laws for choosing a
guru, or a system, or whatever (from Zen
Without Zen Masters):
just because it works for you, doesn't mean that it
works for anybody else.
just because you think that it's working for you,
doesn't mean that it even works for you.
On a separate
web page, http://www.us-shamanics.com/ls-bg.html,
the author of this FAQ has compiled a list of features
that he thinks are important in a light and sound mind
machine. Compare that list of features to the ones advertised
for each machine, and decide which one gives you the
most features you want for the price you can afford.
audio tapes and compact disks seems to vary, just as
much as tastes in music. They all seem to be converging
on the same technologies. Don't buy more than one at
a time from a company; that way, if you decide you don't
like it, you're not out very much.
as much competition in CES, dream machines, or biofeedback
equipment, so for the most part, you'll end up buying
whatever you can afford.
being said, there are certain brand names that come
up over and over again:
users of Synetic, Photosonix, and Mind Gear hardware
seem happy with them.
they're among the cheapest and most heavily promoted,
there are a lot of people out there who have Mind
Gear products, so those are often recommended.
seems to be a general consensus that even if they
do have one or two features that the others don't,
Comptronic Devices' L&S machines are over-priced.
- It seems
that most people who bought Zygon L&S machines
feel ripped off, which may have a lot to do with why
they're not around any longer.
seem to be quite a few people who admire the WaveRider
EEG machines, whether they can afford them or not.
- And MIND-L
is usually almost drowning in personal endorsements
of the Mindwave EEG feedback unit.
light & sound mind machines, different people see
different things. Some see just the flashing light.
Most see swirling patterns that have been compared to
psychedelic light shows or fractals; some in just red
and black, but others in full color. And a few report
seeing detailed, virtual reality like scenes. So people
frequently post to the Mind Machine Digest mailing list
asking why they don't get the primo visuals.
all, your eyes should be closed when using a light &
sound mind machine, as I'm sure you were told in the
manual. You did read the manual, didn't
all, you might try tinkering with some of the settings.
At middle to high frequencies, the light intensity should
be a square wave. If your machine allows you to do so,
change the pulse width. According to many veterans with
these machines, the narrower the pulse width, the better
the visuals. You may also need to adjust the brightness.
You want it bright enough that it fills your field of
vision after filtering through the eyelid, but no brighter.
mind machine includes an audio input port, try combining
your favorite sessions with your favorite music. That
enhances the visuals for most users.
of that works, well, you may just be out of luck on
the visuals, and I hope you bought your machine for
other reasons as well. I've never seen a study on this,
but in my experience, roughly 1 out of every 20 users
don't see anything except flashing light.

The Mind Machine
FAQ is maintained at http://www.us-shamanics.com/mm-faq.html
by J. Brad Hicks, the original author
of the MIND-L FAQ version 0.1 back in 1991.
Hicks also runs a mind machine related business,
& Mechanical Zen, selling and renting mind machines
at pagan festivals, SF conventions, and other events.
This makes him one of the potentially untrustworthy
dealers mentioned above, and he knows it.
