Understanding Brainwaves and EEG readings

The electrical activity emanating from the brain creates frequencies called brainwaves. Brainwave frequencies are measured in Hertz (Hz), meaning cycles per second. The more cycles per second, the greater the Hertz value.

There are four categories of brainwaves ranging from the most activity to the least activity, these are: BETA, ALPHA, THETA and DELTA.

Each image below depicts a one second snapshot of human brainwave activity, as detected by an electroencephalogram (EEG). As you'll notice, greater values indicate more brainwave activity within the one second time-frame.

 

BETA BRAINWAVES are characteristic of an engaged mind, which is highly alert and well focused. Beta activity is quick-connect, fast activity and tends to dominate the normal waking state of consciousness when-attention is directed towards the outside world.

Typically detected in the frontal lobes (where decisions are managed), Beta is usually seen on both sides of the brain in geometric distribution. It may be absent or reduced in areas of brain damage. It is generally regarded as a normal rhythm and tends to be the dominant rhythm in those who are alert, anxious or have their eyes open

 
 

ALPHA BRAINWAVES are slower than beta and can represent a relaxed awareness in the mind. This rhythm is seen when the brain sets itself to rest or reflect. Alpha rates are increased by closing the eyes and relaxation, yet are offset by opening one's eyes or any concentrated effort.

Alpha is usually best detected in the frontal regions of the head, on each side of the brain. Alpha is the major rhythm seen in normal relaxed adults and is typically regarded as the common relaxation mode beyond the age of 13.

 
 
 

THETA BRAINWAVES can indicate drowsiness, daydreaming, the first stage of sleep or 'indirect' imagination/thinking. Theta activity is not often seen in awake adults (unless engaged in a meditative practice), but is perfectly normal in alert children up to 13 years and in most sleep.

A Theta state can be regarded as a gateway to hypnagogic states that lay between being awake and falling asleep. Often Theta entrainment can promote vivid flashes of mental imagery as one becomes receptive to brain/mind information beyond one's typical conscious awareness. Theta has also been identified as a part of learning, memory and reductions in stress.

 
 
 

DELTA BRAINWAVES can reveal deep sleep or slow-wave 'background' thinking. Much like bass sound, Delta tends to be the highest in amplitude and the slowest waves. Delta is often associated with deep sleep. Certain frequencies, in the delta range, have been shown to trigger the body's healing and growth mechanisms.

Interestingly, Delta is the dominant rhythm in infants up to one year, as well as stages 3 and 4 of dreamless sleep.

Brainwave Entrainment and BrainEv - General Precautions and Disclaimer

Although the following statement is required by the FDA, we ask you to pay close attention to the following text so you can determine if the Brain Evolution System is right for you.

None of the statements found at brainevlab.com have been evaluated or verified by the FDA. The Brain Evolution System is not intended to diagnose, cure, treat or prevent any disease. If any medical or psychological matter requires advice or care, please seek consultation with an appropriate, licenced doctor.
  • Under no circumstances should you drive a car or operate dangerous machinery while listening to the Brain Evolution System. This technology can produce very hyper-relaxed states that may endanger you in situations that require your direct attention.
  • Those with an epileptic predisposition may be adversely affected when using brainwave entrainment technology. However rare, there is a risk of seizure associated with individuals who are predisposed to epileptic fits. Consult your doctor directly if you have any questions or concerns regarding audio brainwave entrainment technology's effect on epilepsy.
  • It is not uncommon for repressed emotions or memories to surface as you acquaint yourself with the cause and effects of your brain/mind system. These upwellings are a healthy part of processing and improving how and why we function in some of the ways we do. This emotional processing can lead towards vast improvements in personal development. In highly sensitive situations, it's advisable to seek professional assistance from an appropriate practitioner if you have difficulty processing particular emotions on your own.
  • Do not mix the Brain Evolution System with similar products. Elite Inner Circle, LLC can not determine what will happen when mixing multiple brain enhancement technologies, as this introduces too many variables that could counter the effectiveness of the system.

Sound, Music, Mind and Body

For centuries, music and sound have been used for healing and transformation. From the chanting and ritual of ancient shamans, to Tibetan monks, Peruvian throat singing and Gregorian chants, sound and music have played a central role in the role of shaping human consciousness. Only recently have we begun to pinpoint and understand the phycological effects of sound and music on the brain, mind, and body.

In several settings music proves it can play a crucial role in brain/mind processing. The work of Dr. Lozanov in Bulgaria confirms this. By averaging the effects over multiple listeners, he discovered that music, at 60 beats per minute, (such as in Baroque music) produced the following effects.

· 6% increased Alpha activity (associated with relaxation) · 6% decreased Beta activity (normal waking state) · 4% reductions in pulse and breathing rates (indicating relaxation) · Subjects reported a state of "relaxed awareness"


Later, Dr. Lozanov discovered that he could greatly accelerate learning by using music at this rhythm. This method has become known as “Super Learning”. Through the course of his work, Dr. Lozanov discovered that the timbre, or the tonal quality of the music also greatly affected brain processing.

Conclusion: The timing characteristics of music and the timing of soundwave rates affect the brainwave, stress responses and body rhythms of a listener.

In a study conducted by Dr. Sue Chapman at a New York City Hospital, the response of premature infants to music was studied. One group listened to Brahms lullaby six times a day, while a control group listened to nothing. The group of infants who listened to Brahms gained weight faster, had fewer complications and were released from the hospital an average of a week earlier than those babies who did not listen to Brahms.

Conclusion: The architecture of the music, the rhythm and the timbre all created changes in brain processing through stimulation of the auditory pathways. These changes in the infant's brain/mind processing greatly reduced their stress levels, thereby allowing their natural systems to engage more efficiently than those in the control group.

The profound impact on emotional problems and learning difficulties is shown in the work of Dr. Tomatis in France. Early in his studies, he was called to a Benedictine monastery outside of Paris. The monks were depressed and were having trouble eating and sleeping. Dr. Tomatis was asked to find the cause of their ailments. In the course of his explorations, he discovered that the abbey had recently acquired a new abbot. The new father prided himself on being a modem man, and considered the Gregorian chants too medieval, he had ordered the monks to stop chanting.

Without knowing it, the abbot had taken away a primary form of brain stimulation for the monks. Deprived of the auditory stimulation of the Gregorian chanting, the monks' slipped into a depressed mode.

Conclusion: When Dr. Tomatis had the abbot reinstate the chanting, the depression lifted, and the monks were released from their depressive state.

Understanding the difference between Brain and Mind



Throughout my presentations I often refer to what I call the Brain/Mind System. When I say “brain/mind” I mean the interactive event that occurs between 'the brain' (that fine organ inside your skull), and 'the mind' (the collective matrix which forms your emotional/cognitive/symbolic awareness).

It is important to recognize the distinction between the brain and mind. Like the relationship between car and driver, the brain is the material machinery, which allows 'the mind' to experience and navigate your awareness and actions. 'The mind' in essence does not exist in a physical form, as the brain does.

This ‘mind/brain” definition is based on Dr. Carl Pribram's view of 'the brain' and 'the mind' where "the mind" is a process which runs parallel to physiological processes within the brain. Thus it is possible to have a brain without a mind, as in a cadaver, but it is not possible to have a mind (as defined) without a functioning brain. (This is not to say that there may not be an aspect of consciousness, which operates independently of the brain. I leave you, dear reader, to determine where the seat of one's consciousness lies.)
