Brainwave States
There are several different brainwave states. Your brain cycles through each of these brainwave states many times throughout the day and night. It is a completely natural biological occurrence in every human being.
Your brain doesn’t operate in only one brainwave state at a time but instead pulses in all these states simultaneously, with one of the states being dominant at any given time. The dominant state indicates your “state of mind” or level of consciousness. Because different areas of the brain may have different activity at any given time, you may have activity in one brainwave state in one area of the brain while at the same time a different brainwave state may be more active in another area of the brain. Each of these brainwave states occurs in a specific frequency range. Gamma Gamma brainwave states are the most rapid in frequency. They have received the least attention and research, although more attention is currently being paid to them than in years past. Research has indicated at moments when bursts of insight or high-level information processing occur, there are corresponding increases in brain activity in the Gamma range. The Gamma brainwave state corresponds to frequencies over 40Hz. Beta The Beta brainwave state is associated with a heightened state of alertness and focused concentration. When your mind is actively engaged in mental activities, the dominant brainwave state will be Beta. A person in active conversation, playing sports or making a presentation would be in a Beta state. The Beta brainwave state corresponds to frequencies ranging from 12Hz to 40Hz. |
Alpha
Alpha brainwaves are slower in frequency than Beta brainwaves and represent a state of relaxed mental awareness or reflection. Alpha brainwave states are typically associated with contemplation, visualization, problem solving and accessing deeper levels of creativity. The Alpha brainwave state corresponds to frequencies ranging from 8 Hz to 12 Hz. Theta Theta brainwaves are even slower in frequency and represent a state of deep relaxation and meditation, enhanced creativity, stress relief, light sleep and dreaming. Theta brainwave states have been used in meditation for centuries. Research has proven thirty minutes a day of Theta meditation can dramatically improve a person’s overall health and well-being. Theta meditation has also been known to create the need for less sleep. The Theta brainwave state corresponds to frequencies ranging from 4Hz to 8 Hz. Delta Delta brainwaves are the slowest in frequency and represent a state of deep dreamless sleep. Delta brainwave states have long been associated with healing. While Delta brainwave states usually only occur in deep sleep, it is possible to train yourself to remain awake while reaching the Delta state to experience even deeper levels of meditation and awareness. The Delta brainwave state corresponds to frequencies from 0Hz to 4Hz. |
Binaural Beats
Binaural beats or binaural tones are apparent sounds, the perception of which arises in the brain for specific physical stimuli. This effect was discovered in 1839 by Heinrich Wilhelm Dove, and earned greater public awareness in the late 20th century based on claims that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.
The brain produces a phenomenon resulting in low-frequency pulsations in the amplitude and sound localization of a perceived sound when two tones at slightly different frequencies are presented separately, one to each of a subject's ears, using stereo headphones. A beating tone will be perceived, as if the two tones mixed naturally, out of the brain. The frequencies of the tones must be below 1,000 hertz for the beating to be noticeable. The difference between the two frequencies must be small (less than or equal to 30 Hz) for the effect to occur; otherwise, the two tones will be heard separately and no beat will be perceived. Binaural beats are of interest to neurophysiologists investigating the sense of hearing. Binaural beats may influence functions of the brain in ways besides those related to hearing. Binaural beats reportedly influence the brain in more subtle ways through the entrainment of brainwaves and have been claimed to reduce anxiety and provide other health benefits such as control over pain. This phenomenon is called frequency following response. The concept is that if one receives a stimulus with a frequency in the range of brain waves, the predominant brain wave frequency is said to be likely to move towards the frequency of the stimulus (a process called entrainment). In addition, binaural beats have been credibly documented to relate to both spatial perception and stereo auditory recognition, and, according to the frequency following response, activation of various sites in the brain. The stimulus does not have to be aural; it can also be visual or a combination of aural and visual. Perceived human hearing is limited to the range of frequencies from 20 Hz to 20,000 Hz, but the frequencies of human brain waves are limited over 40 Hz. To account for this lack of perception, binaural beat frequencies are used. Beat frequencies of 40 Hz have been produced in the brain with binaural sound and measured experimentally. When the perceived beat frequency corresponds to the delta, theta, alpha, beta or gamma range of brainwave frequencies, the brainwaves entrain to or move towards the beat frequency. For example, if a 315 Hz sine wave is played into the right ear and a 325 Hz one into the left ear, the brain is entrained towards the beat frequency 10 Hz, in the alpha range. Since alpha range is associated with relaxation, this has a relaxing effect or, if in the beta range, more alertness. An experiment with binaural sound stimulation, using beat frequencies in the Beta range on some participants and Delta/Theta range in other participants, found better vigilance, performance and mood in those in the awake and alert state of Beta range stimulation. |
Binaural beat stimulation has been used fairly extensively to induce a variety of states of consciousness, and there has been some work done in regards to the effects of these stimuli on relaxation, focus, attention, and states of consciousness.
Studies have shown that with repeated training to distinguish close frequency sounds a plastic reorganization of the brain occurs for the trained frequencies and is capable of asymmetric hemispheric balancing. Brain waves
The dominant frequency determines your current state. For example, if in someone's brain alpha waves are dominating, they are in the alpha state (this happens when one is relaxed but awake). However, other frequencies will also be present, albeit with smaller amplitudes.
The brain entraining is more effective if the entraining frequency is close to the user's starting dominant frequency. Therefore, it is suggested to start with a frequency near to one's current dominant frequency (likely to be about 20 Hz or less for a waking person), and then slowly decreasing/increasing it towards the desired frequency. The binaural beats phenomenon was thoroughly researched and tested in 1973 by biophysicist Gerald Oster at Mount Sinai Hospital in New York City. His research on binaural beats and the Frequency Following Response was published in Scientific American and paved the way for further development in the area of auditory stimulation to enhance brain functioning.
Since that time, binaural beat technology has been endorsed by scores of doctors and scientists around the world. By introducing a precise harmonically layered blend of frequencies to your brain via audio technology, you can effortlessly achieve powerful states of focused concentration, deep relaxation and more, while stimulating parts of your brain to work together in synchronization. |

Robert A. Monroe, founder of Hemi-Sync, is internationally known for his work with audio sound patterns that can have dramatic effects on states of consciousness. Monroe observed, during his early research, that certain sounds create a Frequency Following Response in the electrical activity of the brain.
Those observations led to some remarkable findings dealing with the very nature of human consciousness. Researchers learned specific sounds could be blended and sequenced to gently lead the brain to various states, ranging from deep relaxation or sleep to expanded states of awareness and other "extraordinary" states. This compelling research became the foundation of a non-invasive and easy-to-use audio-guidance technology known as Hemi-Sync®. The audio-guidance process works through the generation of complex, multi-layered audio signals, which act together to create a resonance that is reflected in unique brain wave forms characteristic of specific states of consciousness. The result is a focused, whole-brain state known as hemispheric synchronization, or Hemi-Sync®, where the left and right hemispheres are working together in a state of coherence. Different Hemi-Sync® signals are used to facilitate deep relaxation, focused attention or other desired states. As an analogy, lasers produce focused, coherent light. Hemi-Sync® produces a focused, coherent mind, which is an optimal condition for improving human performance. One of the leading researchers into brain wave synchrony, Dr. Lester Fehmi, of the Princeton Biofeedback Research Institute, points out that "Synchrony represents the maximum efficiency of information transport through the whole brain". This means that brain wave synchrony produces a sharp increase in the effects of various brain wave states. The production of synchronized, coherent electromagnetic energy by the human brain at a given frequency leads to a 'laser-like' condition increasing the amplitude and strength of the brain waves. It's evident that a "highly integrated brain," a brain in which both hemispheres are functioning in symmetry, synchrony, harmony and unity, is a key to peak states and peak human performance. |
pecific combinations of Hemi-Sync® signals, for example, can help individuals achieve laser-like focus and concentration. Depending on the intended goals, music, verbal guidance or subtle sound effects are combined with Hemi-Sync® to strengthen its effectiveness.
Naturally, Hemi-Sync® sleep products incorporate predominately Delta frequencies; learning products predominantly Beta, and so forth. Users remain in total control as these recordings do not contain subliminal messages. Hemispheric synchronization does occur naturally in daily life, but typically only for random, brief periods of time. Hemi-Sync® can assist individuals in achieving and sustaining this highly productive, coherent, brain wave state. Continuous Innovation Robert Monroe’s work inspired an entire industry of mind/brain products. After 50 years of research, and thousands of lab sessions, the internationally acclaimed patented Hemi-Sync® process remains unparalleled in its ability to assist us in harnessing our human potential. Thanks to the co-operation of notable medical institutions and universities, the scientifically and clinically proven Hemi-Sync® technology continues to be the focus of a variety of specialized research projects. In addition, many therapists, physicians, educators and other professionals use Hemi-Sync® extensively. Such research is indispensable in revealing the influence of specific Hemi-Sync® sound patterns on consciousness. Over the years, these efforts have resulted in the development of scores of individual products for specific applications such as focused attention, stress management, meditation, sleep enhancement and pain management, to name a few.

This is what Dr Eben Alexander said about Hemi-Sync:
Meditation comes in many different forms. The most useful for me since my coma has been that developed by Robert A Monroe, founder of the Monroe Institute in Faber, Virginia. In my journey of understanding after my coma, Hemi-Sync potentially offered a means of inactivating the filtering function of the physical brain by globally synchronizing my neocortical electrical activity, just as my meningitis might have done, to liberate my out-of-body consciousness.....which enabled me to return to a realm similar to that which I visited deep in coma... |
