An “E – Interview” with Chuck Davis, Creator of the ROSHI EEG/Neurofeedback System

An “E – Interview” with Chuck Davis,
Creator of the ROSHI EEG/Neurofeedback System

Editors Note: Within the AVS / light and sound community, Chuck Davis is known for his knowledge and experience in developing brainwave measurement and entrainment systems. I was fortunate to meet Mr. Davis during a Winterbrain conference a few years back and try his ROSHI EEG/Neurofeedback system. Having used other EEG/NFB systems before, I tried the ROSHI, and taking into account the large number of interested people in the room, found achieving the targeted alpha frequency difficult to attain at first, but after a few minutes felt capable of maintaining that frequency easier than on all the other systems. The ROSHI is definitely “user friendly”.

Chuck has developed one of the finest EEG / NFB systems available in the ROSHI and has recently, in conjunction with Ray Wolfe, created an EEG / AVS interface that will certainly en- hance any neurofeedback training session. Before reading Chuck’s replies to those questions, let’s begin with a little background and contact information:

“After having spent a couple of “lifetimes” in aerospace and the music business, looking for an alpha training instrument, I met Hershel Toomim, of BioComp, in 1979. He was develop- ing BioComp system, on an Apple.

We got into some interesting ideas. After hours of rapping, he hired me. Thence came his BioComp 2001. I designed the infrared communications part. Most anytime, one can find me at 1.323.292.2550.”

Q: How did you initially get involved in eeg/neurofeedback? Did you start out in light/sound or biofeedback? When was that?

A:” During the late ’70s, while in the music business, I started hangin’ out with the `consciousness’ crowd, est, Esalen and the Perls gang, Reichian folk and knew the Late Robt Monroe. Experienced and studied his stuff. Hung out w/ Glenn and Lee Perry and their Samadhi Tank, before they went big time. My first “snap” into pure space, no time, was in the tank. While working for Hershel, my intuitions started to make sense to me. One day, at Hershel’s, this guy came in with a Synchro Energizer. The light bulb flashed on. What better way to set the flicker rates than the brain, itself? This new technique is not concerned with sin- gle frequencies, per se, but /any/ total number of stationary frequencies. Well, almost. Ten years ago, while scanning thru patents, to be sure that I wasn’t going to be stepping on any toes.”

Q: What does ROSHI stand for?

A: “In zendos, there’s a robed fellow that walks around with a little stick. If, during your “sesshin”, you should start dozing off to la la land, you get to experience a whack from that stick. He’s called the Roshi; same as the Maharishi. A teacher/trainer/guru who’s been there, done that. I’ve told a couple people that one of the reasons that called the system, ROSHI,

is that I didn’t have the balls to call it “Maharishi”. I went to school on those folks, with my de- sign rules following the TM® model. The power of the mantra to organize the brain/mind/spirit interface.”

Q: What gave you the motivation for creating the ROSHI?

A: “What is meditation, really? While in Japan, in the ’60s, I asked why those monks sit like that all day. “It toughens you up.” Huh? Needless to say, that stuck with me, for twenty years. I couldn’t afford the other stuff, not even Hershel’s, so I designed my own. In late ’85, I bought an Amiga A1000. It was a perfect opportunity to teach myself effi- cient real-time programming, while putting all of my neurofeedback design rules into one program. It was a truly personal project that went commercial.”

Q: What aspects of your system (ROSHI) are unique, ie, what other NFB systems lack?

A: “First, there’s response time. When I first started writing the code, in 1988, `Visceral’ or *pre- conscious* control of a screen display was on my mind. I figured that the feedback had to be fast enough that the brain operator couldn’t trick it. I’ve received a few barbs about ROSHI’s response time not being that relevant. How would `they’ know, since `they’ don’t know how to do it?”

Q: Could you please explain, in simple terms so us neophytes can understand, what the ROSHI does and how an individual can learn how to operate it?

A: “When a person is deeply, deeply relaxed, into just “blackness”; from there, you use your tal- ent to coach the client to do the ROSHI General Practitioner Protocol [RGPP], or whatever mo- dality you choose to use. From this “space”, with the subject’s critical-logical mind is “quieted”, the client is learning to (Witness the training, rather than `trying to do’ the training. Learning to focus one’s attention, with the least amount of effort; the zone. From this “space”, the immune system, too, can do its “housekeeping”, as it is not being /disturbed/ by the noisy incoherent “conscious mind”. The Complex (adaptive), C (a), EEG coupled L&S protocol, appears to in- duce the brain towards focused attention, it appears to accelerate the boost of the brain’s me- tabolism, blood flow, enough that the subject is able to maintain awareness, during training, without falling to sleep; whereas the average person would have long wandered into zzz land. With this ability to induce the brain to “normalize” itself, through time, the brain begins to pro- duce the neurochemistry necessary maintain this “new” operating region. You can call it a “neuro-mantra”. This EEG driven/coupled protocol is a time domain kinda system. It uses par- tial wavelet/chaos stuff, as it adapts to whatever the raw EEG is doing, even up at subcortical brainstem speeds. With this wideband C(a) protocol, the brain becomes an active phase error detector. With the brain inside of this “closed loop”, phase corrections begin to take place. This takes energy, bloodflow. Wake up, wake up! Now, when the subject has approached this state of “samadhi”, quietude, the trainer can begin coaching to whatever NFB protocol is cho- sen. On the other hand, one can boost the performance of their tapes, CDs or whatever. This combination, along with your current TOVA, MMPI, Beck or whatever, makes for a most pow- erful training system that you’ll have, IMHO, of course ;)”

Q: I understand that you and Ray Wolfe have developed an interface for the ROSHI that allows for the synergistic integration of l/s stimulation. Can you tell us about it?

A: “Yes, indeed! About a year ago, my source for EEG amplifier boards “lost” the ability to deliver anymore of these boards to me.  The structure of the ROSHI(AVS) software is segmented into three parts. None of these three protocols “knows” that the other exists. It is left up to the trainer/clinician/Roshini to integrate them into any protocol they should decide to mock up, for their client’s situation. By moving just the C(a) subroutines onboard the EEG unit, this new EEG front-end gets to be operated as a stand-alone EEG coupled L&S system that can operate on top of, or with *any* BFB/NFB setup. As the serial port communications will be “open platform”, this will allow other “neuro- hackers” to do their programming thing. The ROSHI(AVS) software is a different kind of thing, I think. When coupled to the stand- alone ROSHI2 front-end, it becomes a full blown interhemispheric NFB training system. Briefly, regardless of training modality, it is always pushing the brain operator to be in synch. It brightens things up.”

Q: How often do you personally use the ROSHI? What are your personal goals for doing so? Do you incorporate other modalities while training (light/sound, tactile stimulation, etc.)?

A: “Myself, I do C(a), with EMDR. The ultimate goal of ROSHI is to vanish. I’m not a clini- cian or a trainer. Yes, ROSHI will drive magnetics and CES.”

Q: What’s your definition of the perfect eeg/neurofeedback instrument? If light/sound are part of it, what color LEDs would you use? What type sound stimulation?

A: “Heck, the ROSHI(AVS) NFB system, of course. I leave the choice of LED colors to the cli- nician. I use a simple beep, at training threshold. When I tell people to /make/ the tone beep, they can’t. But, when I instruct them to find a mind “space” where they can *allow* the feedback tone to happen, a little grin comes over their face and, for them, the concept of time begins to vanish; first order meditation. Two different sets of Tru-White® HemiStim type of LED frames are shipped with the system.”

Q: What considerations should someone new to NFB take into account when shopping for NFB equipment?

A: “This is a general response from an exhibit I attended, at Winter Brain, in Miami: “Roshi (tm?) and the Roshi Roshi (Chuck Davis) were present and, as usual, inundated with requests for demo’s. The new model of the Roshi, which runs independently of a computer, is going to be a really neat device. Can’t wait to get one. My Roshi(AVS) session really woke me up, in mid-afternoon, when presentations were putting me to sleep, and left me lucid well into the wee hours.” This recent report was from a Ph.D. clinician who had heard of the ROSHI(AVS), since ’95. From another clinician: “Oh yeah!! That’s what I love about ROSHI. If one is ready to go transpersonal, the ROSHI is ready to take you there.”. As usual, a person should look for price/performance.”

Q: Of all the research studies you have been involved with, is there one in particular that has left a lasting impression on you?

A: “The Tibetan Book of the Great Liberation”, Evans-Wentz “Neurofeedback Treatment of Depression with the ROSHI” has been published, by D. Corydon Hammond, Ph.D., Vol 4(2), in the _Journal of Neurotherapy._ Being able to take a person from the deepest near suicidal depression, to peak performance, without drugs, and to outperform other protocols, is quite a reward for me.”

Q: What do you believe are the most important issues facing NFB today?

A: “Getting more public and HMO acceptance. Zero Prozac, zero Ritalin, please!”

Q: What do you see the future of NFB being?

A: “Strong. NFB is just beginning to look at expansion into more areas, the chiropractic, physical therapy, golf…”

Audio-Visual Entrainment and Diffuse Axonal Injuries

By Dave Siever, C.E.T.

Dave Siever is the President of Mind Alive, Inc. and creator / manufacturer of the Delight and Alert series of audio-visual entrainment mind machine models.


Audio-Visual Entrainment (AVE) is a technique using flashes of lights into the eyes and pulses of tones into the ears at specific frequencies. The frequency of the lights and tones used are in the brainwave frequency range from .5 to 40 Hz. AVE is one of the most intriguing stimulation technologies as AVE devices have been shown to influence, in varying degrees, brain activity by a myriad of influences, not simply frequency driving. As a result of these other effects, we could ponder if we should simply rename the technique as audio-visual stimulation (AVS). Our senses are constantly bombarded by AVS. Consider watching TV or sitting on a street corner watching the traffic. These activities consist of abundant quantities of AVS, yet they don’t have much of an impact on the brain. For instance, when AVE is randomized at ± 1 Hz (for example, 10 Hz would randomize from 9 to 11 Hz), entrainment is reported to provide a significant clinical impact, at ± 2 Hz, the clinical effect is poor and at ± 3 Hz, the clinical effect is all but lost. So it appears that the myriad of effects from AVS only occur when the stimulation is kept fairly rhythmic and therefore entraining, hence AVE. For this reasoning, we will use the term AVE throughout this article. Because AVE affects such a diverse range of neurological processes, it has applications spanning from simple meditation and boosting cognition to the treatment of complex issues such as depression, pain and diffuse axonal injuries (the most common type of brain injury). But first, let’s understand the physiology of AVE.

Turning Procrastination into Action

Turning Procrastination into Action


It takes longer to say the word “procrastination” than it oftentimes takes to begin what needs doing. House cleaning, work-related projects, doing taxes, the list of things people put off is endless. Trouble is we still have to do them.



If you don’t want to do something, for whatever the reason, change your attitude about doing it. Make it fun, make it a challenge, make doing it into something positive because the sooner you complete the task the better you will feel. So how do you change your attitude?

Change your brainwaves. You know, the state of mind you enter when you tell yourself you don’t want to do something – change that! The best way, the fastest and most simplest way for that to happen is by using the DAVID Delight Pro light and sound mind machine by Mind Alive, Inc.

DAVID Delight Pro w/ CES Mind Machine

Here’s how: First, select Session 5 in the Meditation category. It is a 36 minute brainwave frequency entrainment session that gradually lowers your conscious awareness into the Theta mind state for creative visualization. During the session picture the task that is making you procrastinate and ponder ways of making it fun, doable and how easily it can be completed. At session’s end, go back to your Delight Pro and choose Session 3 in the Energize category. That is a 20 minute session proven effective through scientific research for getting energized and motivated. So within an hour you will have the right mindset to successfully complete the project that you have spent far more time procrastinating about.


Try this approach and you will find it to be a valuable tool for those times when you say to yourself you would rather procrastinate than do what needs to get done. You’ll do a lot more in less time than before. And you’ll feel damn good about yourself too!

Overcoming Fear

Overcoming Fear


A customer asked: “We all have fear and most of it comes from our thoughts. And in my business there is fear of rejection, fear of looking foolish, fear of failure, etc…. How would I use the mind machine to help overcome fear?”

DAVID-Delight_PlusDAVID Delight Pro w/ CES Mind Machine

My answer: “By realizing fear is not worth it. Being afraid of something is one thing, but fear is like a preconceived notion that something is going to go wrong. That causes undue stress and anxiety and can lead to failure. Screw-ups are going to happen, so is being rejected. It sucks, but it happens to all of us. Make fear less important in your thoughts, try smiling when you have thoughts of fear. Fear is an unnecessary emotion when it comes to sales so learn to relax and don’t dwell on what makes you fear the unknown, instead turn those negative thoughts of fear into positive feelings of self-confidence. Try an alpha/theta session that is built into the DAVID Delight Plus or Delight Pro by Mindalive or the Procyon or Kasina by Mindplace light and sound brainwave frequency entrainment systems to get you into a hypnogogic state of consciousness where you can visualize any fear into asking yourself why you are fearful of something that hasn’t even happened yet. And smile when fear enters your thoughts, like you are challenging that word because you are better than fear, smarter than fear, and it has no place in your thoughts. It is not welcome in your life the same as all other negative thoughts. Alpha sessions and alpha/theta sessions that are part of the above mentioned mind machines (also known as brain machines and psychowalkmans) are great for reducing anxiety associated with fear.”

If you are in the direct selling business

If you are in the direct selling business…

A customer asked me a very interesting question the other day about training with mindmachines  that is worth sharing with those of you in the business of direct selling. She is in the direct selling business which requires going out talking to people and making phone calls and such. In her past that hasn’t been her personality, She has decided to change herself. She truly enjoys the growth and personal development that comes with it. She studies a lot of training like with Grant Cardone and Tom Hopkins. And she asks: “How would I use my mind machine to help me memorize the training better, and is there a way to make it a part of myself sooner. (Than say the 10000 hours rule)”


To which I replied: “Something I learned long ago from listening to Tony Robbins was where he said your mind will listen to your own words moreso than listening to someone else saying the same thing. So what I do, and have suggested to many others, is record in your own voice the material you want to commit to memory and listen to that audio track while doing a light and sound session. Light and sound brainwave frequency entrainment systems like the DAVID Delight Pro, DAVID Delight Plus, Mindplace Procyon and Proteus are excellent choices when committing to memory what you are learning. Most people choose to use a theta binaural beat frequency session, some find alpha the better choice. For me theta works best, but as all of us are different, what works best for one not always works best for another. Your mind machine has an input port and comes with a stereo patch cord for connecting your audio device to the mind machine unit (sometimes referred to as brain machine, dream machine and psychowalkman) enabling you to do this method.”

Creativity & the California Drought

Creativity & the California Drought

Water conservation has been at the forefront of local news for several months because of the extreme water shortage here in Southern California. So I put my DAVID Delight Pro mind machine to the test, using an alpha / theta light and sound brainwave frequency session and thinking ‘creativity and the California drought’.


I came up with an idea that saves my household over 150 gallons of water per week. We have rain barrels connected to the gutters surrounding our home for those rare moments when it actually rains and after that one alpha / theta brainwave entrainment session, I had an ‘aha’ revelation…

Since I rarely use bleach-based laundry detergent when I wash clothes and such, why not connect the washing machine grey water to one of the rain barrels?

So I did. Behind the washing machine I changed the pipes so I could either let the grey water flow directly into the rain barrel or flip a switch and have the water flow into the drain pipe like before. It took less than three hours of labor and $40 for parts.

DAVID Delight Pro w/ CES Mind Machine

The result has surprised us all and gotten the attention of our neighbors. Since the retrofit, I have not had to use tap water for inside or outdoor plants or for washing our cars. And concerning the plants, we’ve noticed that affids and other unwanted bugs no longer find our plants to their liking and have gone elsewhere, yet ladybugs and the occasional preying mantis’ still call our yard home.


So if you are like us, living in a drought and looking for ways to decrease your water consumption, think about redirecting the used water from your washing machine. You’ll notice a huge drop in water usage on your next Department of Water and Power bill and feel good about saving water wherever possible. And to come up with original ideas of your own for conserving water, try a creativity light and sound session on the DAVID Delight Pro mind machine!

R.I.P. David McLaughlin

R.I.P. David McLaughlin


David McLaughlin was well known in the light and sound mind machine community. Having worked with the late Rayma Ditson-Sommer, Ph.D. in Scottsdale, Arizona for years, then later taking his knowledge of brainwave entrainment to Egypt and for the last few years Mexico City. It was in Mexico where David did his greatest work, helping women empower themselves who before had little to no self-esteem. David McLaughlin was a leader in his use of mindmachines and his absence will be greatly missed by many.

For me, one of the most fascinating examples of David’s ability in utilizing light and sound brainwave equipment was what he called the “Principle of Thwack”. That name he gave it was hilarious and yet extremely defining. His approach to helping those in need through this principle improved the lives of many. In my book “Mind States: An Introduction to Light and Sound Technology” you can read about David’s principle and exactly what it’s purpose is.

Before his death, David visited his sister in Santa Barbara, California. It was here that the following four 30 second videos were taken. They illustrate how witty and insightful David McLaughlin could be.

Protecting Your Sobriety Against Relapse

Protecting Your Sobriety Against Relapse


Changing the way you think about alcohol and learning to move beyond thoughts of having another drink is one of the hardest modifications to behavior an addict must face. Tools are needed.

One of the most important tools for any recovering alcoholic is a mind machine. It will help reinforce your motivation to quit drinking. With a light and sound mind machine a recovering alcoholic can access their beta, alpha, theta and delta brainwave states of mind. During a mind machine session the user can experience what it is like to be in a deeply relaxed mental, emotional and physical state of awareness. In turn, when a light and sound mind machine session is unavailable, remembering how you felt during a light and sound session will prove immensely beneficial. Simply take two or three deep breaths, release slowly as you do, and you will find your mind automatically relaxes.

Find a mind machine that meets your particular needs. Mindmachines range in cost from under $200 to over $500. Cost does not equate to being better, only having more bells and whistles. Check out the DAVID Delight, Delight Plus or Delight Pro by Mind Alive. These brain machines offer everything a recovering alcoholic needs for preventing relapse.
