The brain has two hemispheres that operate somewhat independently from one another. The two hemispheric structures of the brain are connected by a large nerve, called the corpus callosum, which sends information back and forth between the two sides of the brain. In most people, the left hemisphere controls language, logical thinking, and analytic processes and the right side contains the centers for emotion, intuition, and non-linear creative thinking.
“A light sound machine is a brainwave entrainment tool.  Using sound (headphones) & light (strobe light goggles) stimulation, listeners are gently guided into specific brainwave states. Each audio beat and pulse is a specific frequency. Our minds ‘think’ in terms of frequency. Brainwaves change frequencies based on neural activity within the brain. Hearing and vision are considered the favorable senses for affecting brainwaves safely. By presenting beats and pulses to the brain, the brain begins to mimic or follow the same frequencies. This process is referred to as entrainment. In essence, these instruments speak to the mind in it’s own language – the language of frequency.”
The brain produces electrical signals. These signals change depending on what we are doing and what mental state we are in. For instance when we sleep these signals are different from when we are awake. This brain activity can be measured with EEG. It will output in Hz (Hertz - cycles per second) these electrical signals. The most dominant brainwaves will tell us what sort of state a person is in. The slower vibration (lower Hz), the more relaxed that individual is. Using audio technology we get the brain to start following the beats or pulses in a sound if done exactly right.
I was using Jeffrey Thompson brainwave cd material for several weeks and suddenly developed severe anxiety, headaches in the forehead and dizziness and confusion . I stopped but the symptoms are still with me a week later. Will these symptoms go away? This isn’t some bad kundalini awakens g it something is it ? Will I get better snd how long will it take to go away? Message me at eurydice@cruzio.com or message me in FB at Nicholas Pierotti (the guy in the hat hugging his daughter ) Please let me know
The reported PMS symptoms that improved included: affective lability, anxiety, appetite changes, bloating, breast tenderness, concentration difficulties, depression, fatigue, and irritability. Researchers noted that there was a clear “trend” toward a reduction in social withdrawal as a result of symptoms as well. A total of 49/50 women reported improvements.

Regarding split hemisphere isochronic tones. Think of this as two separate isochronic tones tracks playing independently of each other, one playing in one ear and the other one in the opposite ear. Better still, imagine someone playing and recording a drum beat at a rate of 5 taps per second (5Hz – 5 cycles per second). Then a separate recording of a drum beat is made at a rate of 10 taps per second (10 Hz). You then make an audio track where the left ear/channel hears the 5 drum beats recording and the right ear/channel hears the 10 beat recording. With headphones on, each ear can only hear each respective drum beat and not the other. So you are hearing two different beat recordings at the same time, but it’s different in each ear. A split hemisphere isochronic tones track works just the same. You hear two beats at the same time, not two tones as with binaural beats that create a single beat, but two different speeds of beats in each ear. This is what enables you to stimulate and influence each side of the brain with a different frequency of beat. Binaural beats can only stimulate and influence a whole brain effect using a single beat.
Heart rate variability: A new study suggests that among those with low HRV (heart-rate variability), brainwave entrainment can increase HRV. Researchers studied individuals ages 20 to 70 and administered alpha brain stimulation. The alpha wave stimulation resulted in greater heart-rate variability. Since a low HRV is associated with early mortality and poor psychological and physical health, efforts made to increase it should be regarded as beneficial.

This is probably the most popular choice of frequency. The theta state is a state of tremendous stress relief. The benefits associated with theta level relaxation include improved concentration, reduced hyperactivity and improved memory. While in a state of theta relaxation, one’s blood pressure, breathing and heart rate all slow to a much more restful and healthy level that promotes natural healing. During theta relaxation one may also experience vivid flashes of mental imagery as the mind opens to memories or subconscious information that is not available to the conscious mind during the normal waking state. The theta state is a very deep state of relaxation that is excellent for deep hypnosis and mental programming.
Anxiety: In a review of brainwave entrainment research, there were several studies that investigated short-term stress relief as well as long-term stress or “burnout.” Several used modalities of auditory stimulation, while a couple used audio-visual entrainment. Those with heightened short-term stress and anxiety were undergoing medical treatments, experiencing addiction, and/or were just anxious adults.
Chronic fatigue: Subjective improvements in energy level may be reported by those who increase stimulatory beta and gamma waves. Fast waves tend to be associated with higher levels of arousal. Low arousal is associated with chronic fatigue and may be exacerbated by slow brain waves (e.g. theta and delta). As of now there aren’t any studies that have analyzed various protocols for their effect on a person’s energy or arousal.
The only thing I have found lacking in using your product is that there is no place on your website to register my kudos to you for such an excellent product. I am not new to meditation, nor to brain entrainment products, and I found you product to be really outstanding. I’m completely hooked, love listening to the tracks and they are the best way ever to treat monkey mind. Bada boom, bada bing, in just a few minutes any aggravation I’m experiencing in the outside world, melts away and I am one very blissful and happy camper.

In the average person, the activity of one brain hemisphere is dominant over the other, called brain lateralization. This hemispheric imbalance leads us to experience the world in a black and white way, perceiving separation over connectedness. When brainwave entrainment is used to synchronize brainwave activity in both hemispheres simultaneously, a person can more easily integrate information from all parts of the brain and solve problems with greater intelligence and sensitivity.
Sensorimotor rhythm (SMR) is one final type of brainwave that has been studied. SMR, also known as low beta, is a type of brainwave, which occurs in the sensorimotor cortex, in the 12 to 15 hertz range when that area of the sensorimotor cortex is idle and immobile. The purpose of SMR brainwaves is not well understood, but some neurofeedback practitioners report training to increase SMR brainwaves can be beneficial for people with autism, epilepsy, ADD, insomnia, drug addiction, and as an aide to better manage stress.

I came to the conclusion that it is not necessary, from what I’ve read in the books of numerous spiritual teachers as well as from my own experiences, where some of my most profound leaps in consciousness actually came when I wasn’t struggling. Although there were times when I had to put forward effort, my meditation practice and my spiritual practice really seemed to gain momentum when my heart and my devotion became so deeply engaged that it was no longer merely a discipline, but a profound love affair that was moving me along. Some of my biggest leaps in growth actually came about almost effortlessly.
There isn’t really a one-size-fits-all track or frequency range which is right for all kids while doing homework. So that does make it difficult to recommend one thing in particular, and why I have a number of tracks for studying and focus. If they have already learnt and understood the information, but are just trying to commit it to memory for a test, then I would recommend an alpha track, like the Memorization Study Aid product I have with the 10.4Hz frequency you referred to. If they are still trying to fully understand what is being taught in a workbook, then I would recommend a track that is mainly beta frequencies, like my Study Focus tracks. In the middle, I have a number of tracks which use a combination of beta and alpha wave frequencies, like Study Booster, Study Enhancer and Cognition Enhancer. The last 3 use similar frequencies but deliver the tones and brainwave entrainment effects in different ways. As we are all wired a little differently it does sometimes take a bit of trial and error, to see what method or frequency range works best for the individual. These types of tracks are made for a general audience. In an ideal world, you would hook up to an EEG and see in real time exactly what a person responds to best, depending on the goal and current state of mind.

Biofeedback enhancement: In 1981, researcher Arturo Manns discovered that 15 minutes of stimulation with isochronic tones enhanced biofeedback protocols for bruxism (grinding of teeth). They did this by increasing muscle relaxation superior than standalone biofeedback. Brainwave entrainment is different from biofeedback in that it does not allow the person to consciously control their brainwave state.
Miscellaneous reports have also been made about the advantages of brainwave entrainment with the reviews of numerous users stating that the it can assist in increasing sex drive. Research shows that relaxation, meditation, and good self esteem ensures normal body functions. Furthermore, the brainwave entertainment allows your body to flow in rhythm with the beats therefore if your brain accepts and blends with certain frequencies, this could account for the enhanced sex drive.
Expand your natural alpha brainwaves and theta brainwaves using light sound AVS brainwave entrainment therapy and binaural beats stimulation for creative imagery and meditation. Beta brainwave stimulation is best for heightened athletic performance. Delta brainwaves are for deep, restive sleep. Your neural oscillations and induced activity, in conjunction with ongoing brain activity can be measured via electroencephalography biofeedback and eeg neurofeedback instruments.
I love your tapes! I bought them a few weeks ago and have greatly benefited. I’m also a holistic practitioner and have recommended them to a number of patients. And today when I made my last referral to your website for them to purchase from, it occurred to me that perhaps you have referral discounts, or wholesale prices for practitioners, and that I should ask?
And don’t forget, the super-deep meditation and brain synchronization you’ll experience with Holosync® also creates some truly amazing changes in mental and emotional health. Anger, depression, sadness, anxiety, substance abuse, and a whole universe of dysfunctional feelings and behaviors fall away—even in people who have “tried everything” without success!
This music encourages a state of delta relaxation. Delta brainwaves are most prevalent during deep, dreamless sleep. The delta state is a mostly unconscious state that is essential to one’s physical, emotional, psychological and spiritual wellbeing. People who are able to achieve a state of delta relaxation through meditation will sometimes describe spiritual encounters and out of body experiences. The delta state is perfect for inducing profound spiritual experiences, healing and deep subconscious repatterning. Delta frequency brainwave entrainment music is also a fantastic cure for insomnia.
Theta brainwaves are next highest in frequency above delta and are especially important for many people using brainwave entrainment and meditation because theta waves are at a threshold, forming a link between wakefulness and the subconscious mind. Theta waves bridge between our awake self and the creative and insightful understandings from below our conscious awareness, and while they are not common in awake adults, they are normative for children under 13 years old.

You may already have a good feel for where each of the different brainwave states takes you, and know intuitively what will work for you the best on a day-to-day basis with your meditation practice. If you are a little fuzzy about the differences between the brainwave states, however, and would like to have a really clear, visceral sense of what each state does for you and how they resonate with you physically, mentally, and emotionally, one way you can find out is to listen to Harmonic … [Read more...]
