The Brain-The Last Frontier, at least that’s the way I see it. We know so little about it.

Some scientists think that certain sound waves that mimic certain brainwaves can increase brain creativity, intelligence, control pain or alter psychological states. The brain emits waves that oscillate at different frequencies depending on what the person is doing which led to the term “brainwaves.” Using external waves of certain frequencies, scientists have been able to “entrain” or make the brain take on the same wave lengths.

The Power of Sound: How to Manage Your Personal Soundscape for a Vital, Productive, and Healthy Life by Joshua Leeds (Paperback – Feb. 1, 2001) is a book from Amazon.com that goes into more explanation than I give below. Another book from Amazon is A Symphony in the Brain: The Evolution of the New Brain Wave Biofeedback by Jim Robbins (Paperback – Aug. 5, 2008).

1. In the science of brainwave entrainment there are three types of aural or auditory entrainment. One of the first used is Binaural beats. In this system two tones close in frequency generate a beat frequency at the difference of the frequencies. This is generally not heard in awareness because it is subsonic.

For example, a wave length of 495 Hz tone and another wave length 505 Hz tone, one played into each ear, will produce a subsonic 10 Hz tone that is roughly in the middle of the alpha range. That will affect the state of mind of the person listening. Headphones are necessary for this affect to occur. Each ear hears only one of the tones. For more on Binaural beats you can go to http://www.binaural-beats.com/binaural-beats/?pu=false on the web.

2. The second type is Monaural beats, which are not at all the same as binaural. Monaural beats are the result of the arithmetic sum of the waveforms of two tones as they add or subtract from each other, becoming louder and quieter and louder again. If you have been with someone tuning a guitar using two strings, you will be aware of such a wave when the two strings are of only slightly different frequencies.

It should be noted that when Binaural beats are played through loudspeakers they become monaural.

3. The third type is Isochronic tones. These are evenly spaced tones which turn on and off quickly. They are thought to be an effective auditory entrainment method because they elicit strong auditory evoked response from the thalamus and most people find them tolerable. They have hypnotic qualities, particularly when slightly randomized in frequency.

Isochronic tones are thought to be better than binaural because the brain doesn’t adapt to Isochronic tones the way it can to binaural beats. The difference seems to be that while binaural beat create subsonic beats, Ischonic beats are all audible and more pronounced. The brain doesn’t adapt to the rhythmic tones of the Isochronic and learn to ignore them like it does the Binaural. Here is a website that can help you understand Isochonic beats www.Isochronic-Tones.org.

The science seems to suggest that there is a relationship between sound waves and brainwaves and that sound waves can alter brainwaves in positive ways. In the conclusion of a study, “A Comprehensive Review of the Psychological Effects of Brainwave Entrainment,” 2008, by Tina L. Huang, PhD., she says that findings suggest that Brainwave Entrainment is an effective therapeutic tool, but that more studies needed to be conducted. Her studies showed that people suffering from cognitive functioning deficits, stress, pain, headaches/migraines, PMS and behavioral problems benefited from Brainwave Entrainment.

So it appears that with the help of brain entrainment sound wave, the brain is capable of doing some phenomenal things, such as self-healing, improving intelligence, stopping pain, relaxing, meditating, and much more.

Can the Brain Benefit From Brain Entrainment?

I don’t think space is the final frontier-the brain is. Scientists have much to study about the brain.

There are scientists studying chemicals to change brain chemistry. Some are arguing for mental stimulation to discourage Alzheimer’s. Others think that certain external sound waves mimicking brainwaves can increase creativity, intelligence, control pain or alter psychological states.

I don’t think the final word is in yet. But I do know from personal experience that brain entrainment is a working theory.

In the 1990s when a lot of studies were being conducted on entrainment, I got The Brainwave Suite by Dr. Jeffrey Thompson out of a catalog. There were 4 CDs that included sound wave triggers within ambient music. It was sort of like music anyway. The modern version is BRAINWAVE SUITE: Alpha (Relaxation/Med.), Theta (Insight & Intuition), Delta … (4CD + bklt) – Audio CD (2007) by Dr. Jeffrey Thompson, which you can get at Amazon.com. They also have the separate brainwaves available for MP3 downloads.

The four were Alpha Relaxation and Meditation, Theta Insight and Intuition, Delta Sleep and Rejuvenation and Alpha/Theta Awakened Mind.

My absolute favorite was the Delta sleep CD. I am an avowed insomniac and this CD always put me to sleep. My only problem with it was that I wore bulky earphones and they would bother me into wakefulness, just long enough to pull them off. My second favorite was the Alpha Relaxation and Meditation. The first part of the CD helped me calm down and the second led me into a deep meditation.

I didn’t use the Theta too much. I tried to play it and the Alpha/Theta while I typed, but I couldn’t do that. I know that most teens these days do all their work to blaring music, but I like and need my quiet. Science seems to suggest that there is a relationship between sound waves and brainwaves and that sound waves can alter brainwaves in positive ways.

In the conclusion of a study, “A Comprehensive Review of the Psychological Effects of Brainwave Entrainment,” 2008, by Tina L. Huang, PhD., she states that findings suggest that Brainwave Entrainment is an effective therapeutic tool. People suffering from cognitive functioning deficits, stress, pain, headaches/migraines, PMS and behavioral problems benefited from Brainwave Entrainment, but that more studies needed to be conducted. She did mention that it appeared that Beta stimulation increased overall intelligence as did a sound wave test that alternated between 14 and 22 Hz (Beta brainwaves are within the 13-40 Hz range).

These days there are many more brain entrainment programs to choose from. For example you can go to the Ultimate Brainwaves Store, the most Efficient Brainwave Technology with no headphones required and a free MP3 program at www.Brainwave-Meditation.net

I think that people found as I did that brainwave entrainment works, even though the research itself is sparse.

It appears that the brain is capable of doing some phenomenal things, like self-healing, improving intelligence, relearning how to stop pain, relax and relieve stress, improve behavior, and much more with the help of brain entrainment sound waves.

Brainwaves and Brain Entrainment

What do you supposed is the final frontier? I believe it is the brain. The brain is far from understood right down to the electrical pulses that show up in electroencephalographs, commonly known as brainwaves.

Scientists have named the outer parts, some of the inner parts, some of the chemicals inside and what they do; but there is so much scientists don’t understand at all. Can Alzheimer’s be controlled, can IQ be increased? What causes mood disorders like Bipolar or schizophrenia? Can ADD, ADHD, autism, and epilepsy be cured? Are these things linked to brainwaves?

There are scientists using chemicals to change brain chemistry. Other scientists argue for mental stimulation to discourage Alzheimer’s. Another branch thinks that certain sound waves the mimic certain brainwaves can increase creativity, intelligence, control pain or alter psychological states.

It is not strange that the mind has brainwave activity and that music also is made of sound wave activity. This is no coincidence. Most people love music. It moves them to dance, sing, relax and even fall asleep. It’s full of sound waves that react with our brainwaves. In one scientific study, “Auditory Driving as a Ritual Technology: A Review and Analysis,” 2005, Gabe Turow states that he has evidence that music alters mood and has been useful to treat various illnesses probably by altering the brainwave patterns. External sound waves alter the body’s brainwaves.

This is called Brainwave entrainment. Brainwave entrainment is any practice that aims to cause brainwave frequencies to fall into step with an external periodic stimulus having a frequency corresponding to the intended brain-state. This can be auditory and or visual stimulation. You can find out more from this website–www.transparentcorp.com/products/np/entrainment.php.

In other words when Brain Entrainment exposes the brain to external special tones or sights that are pulsed at specific frequencies, the brain will synchronize its own electrical impulses to that same frequency. This means the brain becomes “entrained” to (matched to) the specific frequency of the pulses, which give a person the ability to choose the primary frequency the person wants to experience in the brain. The choice is made by choosing to listen to certain frequencies.

To guide the brain into higher and faster frequency brainwave patterns, the person listens to music in the beta wave length (which range is between 13-40 Hz). In a 1999 study by Frederick J. Lubar et. al., they discovered that when a person listens to sound waves at 18.5 Hz, some people’s brains responded by increasing to 18.5 Hz EEG activity. If the people tested both saw visual sights that pulsed at 18.5 Hz and heard auditory waves, almost half of their brains reached 18.5 Hz EEG activity. This is generally considered within the lower range of Beta brainwaves.

Many of these people saw a reduction in symptoms while they were on this program. Some of the symptoms that were reduced include muscle fatigue, insomnia, dizziness, headache, and TMJ pain. It appears that an external source of sound waves can have an effect on the brain. Amazon.com has this CD that helps Heal Your Headache, Migraines be Gone: the Migraine Brain Wave Entrainment Self Hypnosis System by Dr. Jane Maati Smith C.Hyp. Msc.D. (Audio CD – Dec. 29, 2008). This product that can be purchased on the internet can help-http://www.meditationprogram.com/meditation/ . So can this CD that you can get from Amazon.com-Awakened Mind System 2.0 by Dr. Jeffrey Thompson (Audio CD – June 29, 2004).

There have been studies that show this is temporary and others that it is permanent. More study needs to be done, but it appears that external sound waves do affect brainwaves.
