With digital upgrades, Berger’s machine is still in use today, known as an electroencephalography machine, or EEG. Berger used his machine to study the brains of psychologically normal and abnormal people and discovered the first brainwave, called the alpha wave and also known as the Berger wave, along with the faster beta wave, which he observed suppressing the alpha wave when subjects opened their closed eyes. 
Since most of us spend our days in the beta state, EquiSync excludes the beta brainwave frequencies, and entrains only those responsible for the most beneficial brainwave states: alpha, theta, and delta waves. The two charts on this page illustrate the basic benefits of each brainwave state as well as the basic targeting of the EquiSync programs 1, 2, & 3.
Deep relaxation is another major benefit resulting from the brains cortical frequency following response while using brainwave entrainment. As the brain tends to mimic the rate of frequency it is exposed to, thus allowing it to enter into that brainwave state, this helps explain why this technology can produce benefits commonly found with meditation.

All brainwave states serve important mental functions, and with today’s lifestyle, returning to a peaceful way of being is becoming increasingly difficult to achieve and maintain for any period of time. This continual stress or alerted state causes disease in the mind and body, which is why it’s paramount for us to relearn or retrain ourselves to get back to these healthful and rejuvenating states.

If the further development of consciousness and awareness is your ultimate goal, there really is no substitute for actual meditation, of which many techniques are the result of thousands of years of human endeavor and accumulated knowledge and experience. Sure, it's not as easy as putting on headphones and pushing a button, but achieving authentic inner peace and relief from the stresses of human existence will mean so much more to you when earned through the time-tested route of traditional meditation. (Plus, once you learn to actually meditate, you can do it anywhere anytime without having to rely on being plugged in to something!)


Insomnia and PTSD for most of my life are real bears that I wrestle with every night. A brain neural-therapist (for lack of a better description) said that this kind of sound recording may help. It is not music. When I remember to play the disc, I fall asleep within the first 5-8 minutes. One day I played the disc while cleaning and I was very surprised to hear how much of the recording I never recall hearing before. That's why I know how long it takes to fall asleep.

With so many thoughts begging for your attention each day, it’s hard to believe that most of them are the same ones you had yesterday. Actually, many psychologists who have studied the thought processes associated with our thinking patterns would agree that, on average, 90% of the thoughts that we become aware of throughout the day are the same thoughts that we have already experienced, over and over again. The reason we are so prone to repetitive thinking is because the brain is always … [Read more...]

I tried other companies the last few years or so….among the likes that mainly used binaural audio and the deepest I was really ever to achieve was alpha state….maybe theta once or twice over the last few years. It takes incredible dedication and practice to achieve the deep, renewing states of meditation that are most sought after…..I listened to the theta meditation mp3 last night and within what seemed like a few minutes my mind was flooded with imagery…memories long gone…my body was sleeping, heavy as lead, but my mind was crystal clear, aware of my surroundings. I could barely even open my eyes!
Until NeuralSync™, brainwave entrainment involved inferior linear, single or sequential protocols - such as binaural beats or isochronic tones - that were natively restricted in their ability to affect the natural complex dynamics of the brain. But now, NeuralSync™ significantly improves entrainment by incorporating EIGHT SEPARATE BUT SYNERGISTICALLY-INTERACTIVE DIMENSIONS into a dynamic and cohesive process powerful enough to compel the brain to produce whole-brain synchronization for intense effect. Incredibly superior to binaural beats or isochronic tones, NeuralSync offers an entrainment experience beyond anything you've used before.

Rudy's primary work is on Alzheimer's. In this disease, beta amyloid proteins form plaques in the brain and kill nerve cells eventually leading to dementia. Research from Washington University School of Medicine in St. Louis shows that when people's brains are in a Delta brain wave state, beta amyloid production in the brain ceases and the toxic material is cleared away. One thought is to explore the possibility of using brain entrainment technology to help treat Alzheimer's, but at this point all it is being used for is to help people meditate, relax and dream instantly and effortlessly.


 It is a good idea to follow any instructions outlined by the makers of any type of brainwave entrainment product or program, and to ease yourself carefully into using it. If experiencing any negative side effects, take a break and come back to it later. Brainwave entrainment audios are not recommended for children under the age of 18, and should not be used while driving or operating heavy machinery.
Good to hear from you and glad you got some value from the article. In total honesty I do feel that brainwave entrainment is safe, and that the big point is not to over-use it, or to push yourself too hard. You can almost think of it like an herb or nutritional supplement. You don’t expect big results the day/week of taking it, and if you don’t get results, you don’t keep taking more. You take it in regular safe doses over a recommended period of time and let it synergistically work its magic. Generally I think you are safe to listen to the audio you made, I just recommend taking it gradually with gamma in particular. Listen for just 10-15 minutes at first and see how your brain handles it. If it doesn’t produce any unwanted feelings then jump right in. But even then I recommend only listening once per day, and taking one day off per week.

Many people experienced in using alpha brainwave entrainment report that the state of mind associated with alpha waves is a time when they feel most consciously connected to their subconscious mind. The intense experience of hypnagogic sleep, reported by some people as a feeling of being awake and asleep at the same time, is also associated with alpha brainwaves.
AVE is capable of producing situationally appropriate brain wave frequencies through the process of entrainment (the tendency of physiological processes to mirror environmental stimuli). AVE also increases cerebral blood flow (blood flow in the brain) and increases the metabolization of glucose in the brain for improved functioning of the neurons. The combined outcome of these processes is improved mental performance. It is an effective, inexpensive alternative therapy for many disorders such as anxiety, Attention Deficit Disorder (ADD), Seasonal Affective Disorder (SAD), PTSD, Fibromyalgia and chronic pain. Our AVE devices are also used successfully to boost physical performance for athletes, academic performance for students and cognitive performance for seniors.
Isochronic tones work just the same in delta as they do in alpha, theta and beta and they are widely used in the brainwave entrainment community to help people sleep. Like you, I’ve also seen some websites saying they don’t work in delta, but it’s a bit like the game of Chinese Whispers, where someone makes a comment and then after it gets passed around and shared a lot the message gets distorted and appears to be a fact. I don’t know of any scientific reason why they wouldn’t work in delta. I remember some people talking about this on a brainwave entrainment forum many years ago. They were saying they found isochronic tones a bit too abrupt for using to help them sleep and they preferred binaural beats, as they thought they were a more soothing sound. That was just a personal preference shared by a couple of prominent forum members at the time and some people then took that as a fact for everyone. That’s where I think that belief originated from.
When delta waves are present, our awareness of the external world decreases and shuts off. People with ADD have problems with delta waves occurring when they are trying to focus, and focus and attention become increasingly impossible with stronger delta waves. Studies show a reduction of anxiety, improvements in insomnia, and elimination of headaches when people engage in sessions of delta brainwave entrainment.
Hi Rona, thanks for your compliments on my videos and the music I use, I’m pleased you’ve found them helpful. Regarding the pulse-like sound you’ve been hearing, I’ve never had anyone report something similar to that before. I also haven’t heard anyone on brainwave entrainment forums mention it. That is very unusual and because I’ve never come across it before, I’m afraid I don’t know what would cause that.

Neural oscillations are rhythmic or repetitive electrochemical activity in the brain and central nervous system. Such oscillations can be characterized by their frequency, amplitude and phase. Neural tissue can generate oscillatory activity driven by mechanisms within individual neurons, as well as by interactions between them. They may also adjust frequency to synchronize with the periodic vibration of external acoustic or visual stimuli.[3]
